Abstract
PURPOSE Central nervous system involvement by Brucella species is the most morbid form of brucellosis disease. Studies on neurobrucellosis are scarce and limited to case reports and series. Brucella is unable to infect or harm neurons without the assistance of monocytes. This raises the question of whether ceftriaxone-based regimens are effective. METHODS The primary aim of this study was to identify, evaluate, and summarize the findings of all relevant individual studies in the past 30 years to help better understand the disease. To achieve this, a broad systematic search was undertaken to identify all relevant records. Epidemiological and clinical features of the disease were assessed by the pooled analysis of descriptive studies. Through a meta-analysis, the treatment period duration was compared between the ceftriaxone-based and oral regimens using Standardized mean differences to measure effect size. RESULTS 448 patients were included in the Meta-analyses from 5 studies. A moderate positive effect was found for ceftriaxone-based regimens over oral treatments, and there was a significant difference between these two groups (SMD 0.428, 95% CI -0.63 to -0.22, I 2 = 37.64). Neurobrucellosis has a different clinical picture in pediatric patients. The disease is less chronic in children. Fever, nausea and vomiting, fatigue, and abdominal pain were significantly more prevalent symptoms in children, and Convulsions, ascites, sensorineural hearing loss, and papilledema were significantly more prevalent signs in children than adults. CONCLUSION It is recommended to initiate the treatment of neurobrucellosis with IV ceftriaxone therapy in combination with oral therapy.

Abstract
Brucellosis, a zoonotic disease caused by Brucella species, poses a significant global health concern. Among its diverse clinical manifestations, neurobrucellosis remains an infrequent yet debilitating complication. Here, we present a rare case of neurobrucellosis with unusual presentations in a 45-year-old woman. The patient's clinical course included progressive lower extremity weakness, muscle wasting, and double vision, prompting a comprehensive diagnostic evaluation. Notable findings included polyneuropathy, elevated brucella agglutination titers in both cerebrospinal fluid and blood, abnormal EMG-NCV tests, and resolving symptoms with antibiotic therapy. The clinical presentation, diagnostic challenges, and differentiation from other neurological conditions are discussed. This case underscores the importance of considering neurobrucellosis in regions where brucellosis is prevalent and highlights this rare neurological complication's distinctive clinical and radiological features. Early recognition and appropriate treatment are crucial to mitigate the significant morbidity associated with neurobrucellosis.

Abstract
BACKGROUND It is challenging to diagnose brucellosis in nonendemic regions because it is a nonspecific febrile disease. The accurate identification of Brucella spp. in clinical microbiology laboratories (CMLs) continues to pose difficulties. Most reports of misidentification are for B. melitensis, and we report a rare case of misidentified B. abortus. CASE PRESENTATION A 67-year-old man visited an outpatient clinic complaining of fatigue, fever, and weight loss. The patient had a history of slaughtering cows with brucellosis one year prior, and his Brucella antibody tests were negative twice. After blood culture, the administration of doxycycline and rifampin was initiated. The patient was hospitalized due to a positive blood culture. Gram-negative coccobacilli were detected in aerobic blood culture bottles, but the CML's lack of experience with Brucella prevented appropriate further testing. Inaccurate identification results were obtained for a GN ID card of VITEK 2 (bioMérieux, USA) and matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) using a MALDI Biotyper (Bruker, Germany). The strain showed 100.0% identity with Brucella spp. according to 16S rRNA sequencing. MALDI-TOF MS peaks were reanalyzed using the CDC MicrobeNet database to determine Brucella spp. (score value: 2.023). The patient was discharged after nine days of hospitalization and improved after maintaining only doxycycline for six weeks. The isolate was also identified as Brucella abortus by genomic evidence. CONCLUSION Automated identification instruments and MALDI-TOF MS are widely used to identify bacteria in CMLs, but there are limitations in accurately identifying Brucella spp. It is important for CMLs to be aware of the possibility of brucellosis through communication with clinicians. Performing an analysis with an additional well-curated MALDI-TOF MS database such as Bruker security-relevant (SR) database or CDC MicrobeNet database is helpful for quickly identifying the genus Brucella.

Abstract
BACKGROUND Neurobrucellosis (NB) is a rare and serious complication of brucellosis. Its clinical manifestations vary, with no obvious specificity. At present, there is no clear clinical diagnosis or treatment for reference. In this study, we retrospectively analyzed the clinical data for 21 patients with NB to provide reference data for its further study. METHODS We analyzed the epidemiological and clinical manifestations, laboratory tests, imaging examinations, cerebrospinal fluid, and treatment plans of 21 patients diagnosed with NB in the Department of Neurology, Xuanwu Hospital, Capital Medical University Beijing, China. RESULTS The ages of the patients ranged from 15 to 60 years old (mean age 40.1 ± 13.33 years), the male: female ratio was 4.25:1. Thirteen patients had a history of animal (sheep, cattle) contact, three had no history of animal contact, and the contact status of four was unknown. Brucella can invade various systems of the body and show multi-system symptoms, the main general manifestations were fever (66.67%), fatigue (57.14%) and functional urination or defecation disturbance (42.86%). The main nervous system manifestations were limb weakness (52.38%) and hearing loss (47.62%).The main positive signs of the nervous system included positive pathological signs (71.43%), sensory abnormalities (52.38%), limb paralysis (42.86%). Nervous system lesions mainly included spinal cord damage (66.67%), cranial nerve involvement (61.90%), central demyelination (28.57%) and meningitis (28.57%). In patients with cranial nerve involvement, 69.23% of auditory nerve, 15.38% of optic nerve and 15.38% of oculomotor nerve were involved. The blood of eight patients was cultured for Brucella, and three (37.5%) cultures were positive and five (63.5%) negative. The cerebrospinal fluid (CSF) of eight patients was cultured for Brucella, and two (25.00%) cultures were positive and six (75.00%) negative. Nineteen of the patients underwent a serum agglutination test (SAT), 18 (94.74%) of whom were positive and one (5.26%) of whom were negative. A biochemical analysis of the CSF was performed in 21 patients, and the results were all abnormal. Nineteen patients underwent magnetic resonance imaging (MRI). Twenty-one patients were treated with doxycycline and/or rifampicin, combined with ceftriaxone, quinolone, aminoglycoside, or minocycline. After hospitalization, 15 patients improved (71.43%), two patients did not recover, and the status of four patients was unknown. CONCLUSIONS The clinical manifestations, CSF parameters, and neurological imaging data for patients with NB show no significant specificity or correlations. When patients with unexplained neurological symptoms accompanied by fever, fatigue, and other systemic manifestations in a brucellosis epidemic area or with a history of contact with cattle, sheep, animals, or raw food are encountered in clinical practice, the possibility of NB should be considered. Treatment is based on the principles of an early, combined, and long course of treatment, and the general prognosis is good.

Abstract
Brucellosis is a zoonotic disease endemic in many developing countries, including Türkiye. Among the species that are pathogenic for humans; Brucella melitensis is isolated from livestock animals like sheep and goats, Brucella abortus from cattle and Brucella suis from pigs. Laboratory diagnosis of infection caused by Brucella species with gram-negative coccobacillus morphology; can be made through characteristic culture features, serological tests and molecular methods. Brucellosis, which has a wide distribution of clinical signs and symptoms; can cause various complications by affecting many organs and systems. Among all complications, the probability of thyroid abscess is less than 1%. In this case report; an example of thyroid abscess, one of the rare complications of brucellosis that is not frequently encountered in the literature, was presented. During the physical examination of a 45-year-old female patient who admitted with the complaint of pain in the neck area, fever, neck swelling, redness and pain that increased with palpation were detected. Leukocytosis, lymphopenia, high sedimentation and CRP, low TSH and high T4 values were detected in laboratory tests and subacute thyroiditis was considered as the preliminary diagnosis. Surgical abscess drainage was planned as the patient's clinical findings progressed during follow-up and spontaneous pus discharged from the midline of the neck. The abscess aspirate sample taken during surgical intervention and the blood culture samples taken before were evaluated microbiologically. Microorganisms that did not grow on EMB agar but grew on 5% sheep blood and chocolate agar at the 72-96th hour of incubation of culture plates; were detected to have gram-negative coccobacillus morphology and positive for catalase, oxidase and urease. Although the Wright test was negative with a titer of 1/20, the Rose Bengal test was positive, Coombs test was positive with a titer of 1/160 and the Brucellacapt test was positive with a titer of >1/5120. Microorganisms growing on culture plates were identified as B.melitensis at the species level with specific antisera. As a result of antibiotic susceptibility tests evaluated according to the European Committee on Antimicrobial Susceptibility Testing version 14.0 (EUCAST v14.0), the isolate was susceptible to rifampicin, doxycycline, gentamicin and trimethoprim-sulfamethoxazole at standart dosing regimen and susceptible to ciprofloxacin and levofloxacin at increased exposure. The patient, who was started on doxycycline and rifampicin combination treatment, was discharged without any complaints. In the diagnosis of infection due to Brucella species, which is one of the pathogens that early diagnosis and initiation of treatment greatly affects the prognosis; in addition to culture, which is the gold standard method, serological tests are also very important. If diagnosis is delayed, complications may develop due to involvement in almost every part of the body, depending on the affected organs and systems. In areas where brucellosis is endemic, patients with symptoms such as neck swelling, shortness of breath and difficulty in swallowing, thyroid tissue involvement due to brucellosis should definitely be considered etiologically.

Abstract
RATIONALE Rifampicin, as a main chemotherapy drug treating brucellosis, is widely used in clinical practice. Rifampicin-associated ARF is not rare, especially in those rifampicin re-exposure patients. However, this was rare complication of severe renal involvement due to multiple factors including rifampicin, nephrotoxic gentamicin, and contrast medium, and few studies have reported it. PATIENT CONCERNS A 59-year-old male presented to our hospital with acute renal failure (ARF) caused by anti-brucellosis treatment with rifampicin (675 mg/day), gentamicin (320 mg/day), and doxycycline (200 mg/day). He had a contrast-enhanced CT of the upper abdomen before the onset of. After stopping rifampicin and undergoing integrated therapy, the patient's renal function gradually recovered. DIAGNOSES Considering that the patient had a history of using rifampicin for pulmonary tuberculosis in the past, based on the examination results, the patient was diagnosed with rifampicin-associated ARF. INTERVENTIONS Symptomatic treatment such as hemodialysis, and anti-brucella treatment with doxycycline and moxifloxacin were given. OUTCOMES The patient had significant anuric and polyuric periods and acute tubular necrosis is considered. After treatment, his renal function and urine volume returned to normal, and Brucella melitensis was not isolated from blood cultures. LESSONS The case reveals that severe renal involvement due to multiple factors including rifampicin, nephrotoxic gentamicin, and contrast medium. Misdiagnosis and mistreatment can deteriorate the patient's condition. Renal function should be closely monitored in the susceptible patients. Early recognition can provide appropriate therapy to patients. If unexplained renal failure during the use of rifampicin, especially in those rifampicin re-exposure patients, rifampicin-associated ARF should be considered.

Abstract
BACKGROUND Human brucellosis is a neglected, re-emerging, and endemic zoonosis in many countries. The debilitating and disabling potential of the disease is a warning about its morbidity, generating socioeconomic impact. This review aims to update the current evidence on the efficacy and safety of therapeutic options for human brucellosis using the network meta-analysis (NMA). METHODOLOGY A systematic search was conducted in four different databases by independent reviewers to assess overall therapy failure, adverse events, and time to defervescence associated with different therapies. Randomized clinical trials (RCTs) evaluating any therapeutic drug intervention were selected, excluding non-original studies or studies related to localized forms of the disease or with less than 10 participants. Data were analyzed by frequentist statistics through NMA by random effects model. The risk of bias and certainty of evidence was assessed, this review was registered at PROSPERO. RESULTS Thirty-one (31) RCTs involving 4167 patients were included. Three networks of evidence were identified to evaluate the outcomes of interest. Triple therapy with doxycycline + streptomycin + hydroxychloroquine for 42 days (RR: 0.08; CI 95% 0.01-0.76) had a lower failure risk than the doxycycline + streptomycin regimen. Doxycycline + rifampicin had a higher risk of failure than doxycycline + streptomycin (RR: 1.96; CI 95% 1.27-3.01). No significant difference was observed between the regimens when analyzing the incidence of adverse events and time to defervescence. In general, most studies had a high risk of bias, and the results had a very low certainty of evidence. CONCLUSIONS This review confirmed the superiority of drugs already indicated for treating human brucellosis, such as the combination of doxycycline and aminoglycosides. The association of hydroxychloroquine to the dual regimen was identified as a potential strategy to prevent overall therapy failure, which is subject to confirmation in future studies.

Abstract
Periprosthetic hip infection caused by Brucella abortus is rare and only a few cases have been reported. This current case report presents a case of a man in his early 50s who developed periprosthetic hip infection 2 years after right hip arthroplasty. There was no fever or pain, the usual cardinal signs of infection, except for a sinus tract at the previous surgical incision. Laboratory and arthrocentesis culture examinations (done twice) confirmed infection with B. abortus. Accordingly, a two-stage revision surgery was performed accompanied by antibiotic treatment with doxycycline and rifampicin after each stage. There was no recurrence at the 2-year follow-up, with good functional recovery of the hip joint. Clinically, this case serves to highlight the fact that periprosthetic hip infections caused by B. abortus might not present with the typical symptoms such as fever or hip pain. Furthermore, this current case involved a chronic sinus tract, so the diagnostic and therapeutic course of this case offers useful insights for managing similar cases in the future. In addition, a review of the literature on the diagnosis and treatment of Brucella-caused periprosthetic hip infection is presented.

Abstract
AIM Brucellosis is a zoonotic infection that can affect almost every organ. A mild elevation of aminotransferase levels is usually observed in liver involvement. However, the development of clinical hepatitis is rare. In this study, we aimed to present the hospitalized cases with brucellosis hepatitis in our clinic in a 13-year period. METHODS A hundred and three patients with significant hepatobiliary involvement, diagnosed by microbiological analysis, were included in the study. For the presence of hepatitis, it was required that the aminotransferases must be ≥ 5 times more than the upper limit and/or the total bilirubin level must be ≥ 2 mg/dl and/or the local hepatic lesion must be demonstrated. RESULTS Of the cases, 35.9%, 17.5%, and 46.6% had clinical hepatitis, cholestatic hepatitis, and both clinical and cholestatic hepatitis, respectively. The most frequent symptom was fever (85.4%) while the most preferred treatment options were combinations containing aminoglycosides. It was observed that the mean time-interval to decrease to normal values of ALT, AST, and bilirubin values was 15.2 ± 7.8 days while the patients having their treatment regimens. In our study, which focused on liver involvement, it was found that a chronic liver disease did not develop in any of the cases. CONCLUSION Our study showed that, even in the presence of hepatitis, clinical response and laboratory improvement were high with appropriate treatment. It was observed that the improvement in aminotransferases and total bilirubin values delayed in the cases with blood culture positivity, secondary organ involvement, and alanine aminotransferase/aspartate aminotransferase > 1.

Abstract
Background: Brucellosis is a pervasive zoonotic disease caused by various Brucella species. It mainly affects livestock and wildlife and poses significant public health threats, especially in regions with suboptimal hygiene, food safety, and veterinary care standards. Human contractions occur by consuming contaminated animal products or interacting with infected animals. Objective: This study aims to provide an updated understanding of brucellosis, from its epidemiology and pathogenesis to diagnosis and treatment strategies. It emphasizes the importance of ongoing research, knowledge exchange, and interdisciplinary collaboration for effective disease control and prevention, highlighting its global health implications. Methods: Pathogenesis involves intricate interactions between bacteria and the host immune system, resulting in chronic infections characterized by diverse clinical manifestations. The diagnostic process is arduous owing to non-specific symptomatology and sampling challenges, necessitating a fusion of clinical and laboratory evaluations, including blood cultures, serological assays, and molecular methods. Management typically entails multiple antibiotics, although the rise in antibiotic-resistant Brucella strains poses a problem. Animal vaccination is a potential strategy to curb the spread of infection, particularly within livestock populations. Results: The study provides insights into the complex pathogenesis of brucellosis, the challenges in its diagnosis, and the management strategies involving antibiotic therapy and animal vaccination. It also highlights the emerging issue of antibiotic-resistant Brucella strains. Conclusions: In conclusion, brucellosis is a significant zoonotic disease with implications for public health. Efforts should be directed towards improved diagnostic methods, antibiotic stewardship to combat antibiotic resistance, and developing and implementing effective animal vaccination programs. Interdisciplinary collaboration and ongoing research are crucial for addressing the global health implications of brucellosis.

Abstract
Brucellosis is an infectious disease caused by different species of Brucella bacteria. It is also known as Malta fever, one of the neglected diseases that can cause infection in both animals and humans. Although human-to-human infection is rare, it can spread through the inhalation of airborne agents, and if left untreated, it can lead to serious health complications. In this review, we aim to highlight the pathophysiology, prevention, epidemiology, mitigation, cure, targets for drug development, and vaccine development against human brucellosis. Human brucellosis is mainly caused by consuming unpasteurized milk or dairy products, uncooked meat, and contact with infected animals. Human brucellosis outbreaks are mainly associated with developing and low- to middle-income countries. Brucella is present all over the world, and only some of the regions are at high risk, including Asia, Africa, Eastern Europe, Mexico, South and Central America, the Caribbean, the Mediterranean Basin, and the Middle East. Because of intracellular survival, inhibition of apoptosis, and immune evasion, Brucella can survive and multiply inside the host cell, which can cause chronic disease. By using proteomics approaches, several new drug targets were reported for human brucellosis that can be used for the development of novel drugs. We can also develop an efficient vaccine against human brucellosis by exploring previously reported vaccine candidates against animal brucellosis. The information provided through this review will facilitate research to control and cure human brucellosis and its complicated symptoms.

Abstract
This is a unique case of retinoschisis as an ocular manifestation of brucellosis. A 38-year-old male presented with recurrent episodes of bilateral eye redness, predominately in his left eye. His visual acuity was not affected, and he did not report any other symptoms. On slit lamp examination, binocular Koeppe nodules of the iris and cells in the left anterior chamber were observed. Fundoscopy followed by meticulous multimodal imaging confirmed left inferior retinoschisis. The patient was diagnosed with panuveitis, and a series of laboratory examinations revealed positive anti-IgM Brucella antibodies. Ocular brucellosis can cause variable, atypical, and serious presentations, hence, early diagnosis is paramount to avoid complications.

Abstract
Background: Brucellosis impact both animals and humans worldwide. However, using antibiotics for brucellosis remains controversial despite decades of research. Relapse can complicate treatment in this area. Since the mid-1980s, microbiologists, and physicians have studied fluoroquinolones' use for treating human brucellosis. The principal advantages of fluoroquinolones are their intracellular antimicrobial activity, low nephrotoxicity, good pharmacokinetics, and the lack of drug-level monitoring. Fluoroquinolones inhibit disease recurrence. In vitro and clinical data were used to study the prevalence of Brucella melitensis and Brucella abortus fluoroquinolone-resistant isolates. Methods: The PubMed, Scopus, Embase, and Web of Science databases were carefully searched until August 6, 2022, for relevant papers. The number of resistant isolates and sample size were used to estimate the proportion of resistant isolates, fitting a model with random effects, and DerSimonian-Laird estimated heterogeneity. Furthermore, meta-regression and subgroup analyses were used to assess the moderators to identify the sources of heterogeneity. Meta-analysis was performed using R software. Results: Forty-seven studies evaluated fluoroquinolone resistance in Brucella spp. Isolates. Fluoroquinolones have shown high in vitro efficacy against Brucella spp. The resistance rates to ofloxacin, sparfloxacin, fleroxacin, pefloxacin, and lomefloxacin were 2%, 1.6%, and 4.6%, respectively. Conclusion: Clinical in vitro tests demonstrated that fluoroquinolones can eradicate Brucella spp. Owing to first-line medication resistance, recurrence, and toxicity, it is essential to standardize the Brucella antimicrobial susceptibility test method for a more precise screening of resistance status. Fluoroquinolones are less resistant to fluoroquinolone-based treatments in modern clinical practice as alternatives to standard therapy for patients with brucellosis relapse after treatment with another regimen and in patients who have developed toxicity from older agents.

Abstract
Nano-based drug delivery systems are increasingly used for diagnosis, prevention and treatment of several diseases, thanks to several beneficial properties, including the ability to target specific cells or organs, allowing to reduce treatment costs and side effects frequently associated with chemotherapeutic medications, thereby improving treatment compliance of patients. In the field of communicable diseases, especially those caused by intracellular bacteria, the delivery of antibiotics targeting specific cells is of critical importance to maximize their treatment efficacy. Brucella melitensis, an intracellular obligate bacterium surviving and replicating inside macrophages is hard to be eradicated, mainly because of the low ability of antibiotics to enter these phagocityc cells . Although different antibiotics regimens including gentamicin, doxycycline and rifampicin are in fact used against the Brucellosis, no efficient treatment has been attained yet, due to the intracellular life of the respective pathogen. Nano-medicines responding to environmental stimuli allow to maximize drug delivery targeting macropages, thereby boosting treatment efficacy. Several drug delivery nano-technologies, including solid lipid nanoparticles, liposomes, chitosan, niosomes, and their combinations with chitosan sodium alginate can be employed in combination of antibiotics to successfully eradicate Brucellosis infection from patients.

Abstract
Brucella epididymo-orchitis (BEO) is a rare complication of brucellosis. Despite the high incidence of brucellosis in developing countries, few case series on BEO are available. This study focuses on the clinical presentations, diagnosis, and treatment of BEO with a review of the literature. This study included consecutive BEO patients diagnosed and treated at Smart Health Tower between 2021 and 2023. The required data were retrospectively collected from patients' profiles. The BEO diagnosis was established through scrotal Doppler ultrasound in cases with a positive Rose Bengal test and positive IgG and IgM results for brucellosis, in addition to scrotal pain and swelling. This study included 11 cases whose ages ranged from 22 to 55 years. Most of the cases presented with testicular pain (72.7%), followed by fever (63.6%) and arthralgia (63.6%). The right side (54.5%) was slightly more affected than the left side (45.5%). The major abnormal laboratory finding was an elevated C-reactive protein (82%). The treatment was conservative, in which a combination of gentamicin, doxycycline, and rifampicin was administered to the patients for about 6-8 weeks. One case underwent an orchiectomy due to the abscess formation. All the patients responded well to the treatment, with no recurrence. In the Middle East, brucellosis remains a concerning infectious disease. Early diagnosis, aimed at preventing abscess formation and other complications, takes first priority to avoid invasive interventions.

Abstract
Catalase, an antioxidant enzyme widely produced in mammalian cells and bacteria, is crucial to mitigating oxidative stress in hostile environments. This function enhances the intracellular survivability of various intracellular growth pathogens, including Brucella (B.) abortus. In this study, to determine whether the suppression of catalase can inhibit the intracellular growth of B. abortus, we employed 3-amino-1,2,4-triazole (3-AT), a catalase inhibitor, in both RAW 264.7 macrophage cells and an ICR mouse model during Brucella infection. The intracellular growth assay indicated that 3-AT exerts growth-inhibitory effects on B. abortus within macrophages. Moreover, it contributes to the accumulation of reactive oxygen species and the formation of nitric oxide. Notably, 3-AT diminishes the activation of the nucleus transcription factor (NF-κB) and modulates the cytokine secretion within infected cells. In our mouse model, the administration of 3-AT reduced the B. abortus proliferation within the spleens and livers of infected mice. This reduction was accompanied by a diminished immune response to infection, as indicated by the lowered levels of TNF-α, IL-6, and IL-10 and altered CD4+/CD8+ T-cell ratio. These results suggest the protective and immunomodulatory effects of 3-AT treatment against Brucella infection.

Abstract
Brucellosis, a zoonotic intracellular bacterial infection primarily transmitted through the consumption of unpasteurized milk from infected animals, remains a challenging condition to clinically control. This is mainly because of the limited effectiveness of conventional antibiotics in targeting intracellular Brucella. Micro- and nanoformulations of antibiotics, whether used as a mono- or combination therapy, have the potential to reduce the antibiotic doses required and treatment duration. Extensive research has been conducted on various organic, semiorganic, and inorganic nanomaterials with different morphologies, such as nanoparticles (NPs), nanotubes, nanowires, and nanobelts. Metal/metal oxide, lipidic, polymeric, and carbonic NPs have been widely explored to overcome the limitations of traditional formulations. In this review, we discuss the advances and challenges of these novel formulations based on recent investigations.

Abstract
Objective The clinical efficacy of perioperative chemotherapy regimen (rifampicin, doxycycline, levofloxacin, ceftriaxone) was evaluated for lumbar brucellosis spondylitis patients with neurological injury. Methods In Beijing Ditan Hospital affiliated with Capital Medical University, 32 patients with lumbar brucellosis spondylitis underwent surgery and triple perioperative chemotherapy (rifampicin, doxycycline, levofloxacin) between 2011 and 2021 due to neurological injury, and 34 patients matched up with the triple group underwent rifampicin, doxycycline, levofloxacin, and ceftriaxone. Both groups were compared in terms of changes in inflammation index, low back/leg pain, lumbar function, neurological function, and adverse drug reactions. Results There was no significant difference in erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), low back pain visual analogue scale (VAS), leg pain VAS, lumbar Oswestry disability index (ODI) and nerve function injury rate between the two groups before chemotherapy (P>0.05). The ESR, CRP at 1 week and 2 weeks after chemotherapy and 1 week, 2 weeks, 1 month postoperatively in the quadruple group were significantly lower than those in the triple group, which is the same to ESR 3 months postoperatively (P<0.05). The low back pain VAS, leg pain VAS and lumbar ODI in the quadruple group were significantly lower than those in the triple group at 1 month and 3 months postoperatively (P<0.05). The recovery rate of neurological function in the quadruple group was significantly higher than that in the triple group at 3 and 6 months postoperatively (P<0.05). Both groups did not experience significantly different perioperative and postoperative adverse reactions (P>0.05). Conclusion For lumbar brucellosis spondylitis with neurological injury, quadruple perioperative chemotherapy of rifampicin, doxycycline, levofloxacin and ceftriaxone can significantly reduce perioperative inflammation, and improve low back/leg pain, as well as promoting neurological function recovery in the short term.

Abstract
BACKGROUND Brucellosis, a common zoonotic disease worldwide, can lead to serious complications in humans. In Oman, the disease occurs most often in the south, but is increasing in the north. OBJECTIVES Describe brucellosis in children in the Northern Governorate in Oman. DESIGN Retrospective, observational. SETTINGS Hospitals in the Northern Governorate in Oman. PATIENTS AND METHODS We collected data on the demographics, distribution, common clinical presentations, risk factors, laboratory findings, therapy, and complications of confirmed cases of brucellosis. We included all brucellosis cases up to the age of 13 years at the Child Health Department in Royal, Suhar, Al Rustaq and Nizwa Hospitals over a 15-year period. MAIN OUTCOME MEASURES Descriptive findings of brucellosis. SAMPLE SIZE 57 confirmed cases. RESULTS The 57 confirmed cases of Brucella had a mean age of 6 years. Most of the cases were from Dhakhiliya 21 (36.8%) and Batinah 18 (31.6%). Consumption of raw milk was documented in 75% and 41% had animal contact. From 2010, there was a marked rise of the cases with a maximum rise was noticed in 2019 with a total of 10 cases. The main clinical manifestations were fever (92%, n=52), arthritis (44%, n=25), which involved mainly knees and hips. Forty-two had bacteremia, 41% anemia, 10% osteomyelitis/septic arthritis, one case with congenital brucellosis and one case neurobrucellosis (1.8%). Forty cases had positive serology results of which 19 had positive cultures. Most cases had received cotrimoxazole and rifampin as the primary treatment regimen 22 (40%). Four patients relapsed (7%) after treatment completion. CONCLUSION This study showed the distribution and clinical characteristics of brucellosis in different regions in the Northern Governorate in Oman. Although the numbers of cases remained low, the gradual increase is concerning for public health and preventive strategies. Further studies are needed to compare this data with the Southern region. LIMITATION Retrospective study with small sample size.

Abstract
Brucella infection often involves multiple organ systems with non-specific clinical manifestations, and cutaneous involvement is uncommon. Splenic infarction and leukocytoclastic vasculitis also rarely occur together in the course of brucellosis infection. We report the case of a 47-year-old man with Brucella combined with splenic infarction. The patient presented with fever; large liver, spleen, and lymph nodes; muscle and joint pain; positive laboratory tests for blood cultures (Brucella abortus); and imaging suggestive of splenic infarction. After treatment with streptomycin, doxycycline, and rifampicin, the patient's clinical symptoms and splenic damage improved. Detailed history taking, correct interpretation of laboratory results, and knowledge of rare complications of human brucellosis facilitate early diagnosis and treatment of the disease.

Abstract
Human brucellosis is a common zoonotic disease in certain regions of the world, especially in rural populations, yet it is often neglected. The index patient presented with prolonged fever and headache. Examination revealed hepatosplenomegaly, and investigations revealed transaminitis with bicytopenia with serological evidence positive for Brucella. The radiological picture suggested granulomatous disease with miliary nodules, and a bone marrow examination revealed a noncaseating granuloma. The case was unique and challenging, as the clinical picture was consistent with epidemiologically prevailing tuberculosis, which is also seen in brucellosis-endemic countries. Brucellosis mimicked disseminated tuberculosis, making the case intriguing to diagnose and treat. The case demonstrated that physicians need to have a high index of suspicion for brucellosis, which should be actively investigated in cases with prolonged fever. It also illustrated the fundamental importance of teamwork and the centrality of the multidisciplinary team in the planning and prioritization of treatment.

Abstract
BACKGROUND The treatment of brucellosis suffers from a high recurrence rate and drug resistance. Our study researched the differences in efficacy and side effects between triple antibiotics therapy and dual antibiotics therapy in the treatment of brucellosis through a systematic review and meta-analysis. METHODS We searched 4 English electronic databases and 2 Chinese electronic databases for randomized controlled trials and cohort studies published through September 2022 on the use of triple antibiotics versus dual antibiotics in the treatment of brucellosis. Overall outcome indicators were therapeutic failure rate, relapse rate, overall therapeutic failure rate, and side effect rate. Relative risk (RR) and 95% confidence intervals (95% CIs) were used as summary statistics. A fixed-effects model was used to combine the overall effect sizes. RESULTS The meta-analysis included 15 studies consisting of 11 randomized controlled trials and 4 cohort studies. Triple antibiotics showed better efficacy than dual antibiotics in a comparison of 3 overall outcome indicators (therapeutic failure rate (RR 0.42; 95% CI 0.30 to 0.59 heterogeneity P = 0.29, I2 = 15%), relapse rate (RR 0.29; 95% CI 0.18 to 0.45 heterogeneity P = 0.88, I2 = 0%), and overall therapeutic failure rate (RR 0.37; 95% CI 0.28 to 0.48 heterogeneity P = 0.35, I2 = 9%)). The incidence of side effects in patients with brucellosis treated with triple antibiotics was not significantly different from that in brucellosis patients treated with dual antibiotics (RR 0.85; 95% CI 0.67 to 1.06 heterogeneity P = 0.1, I2 = 35%). Sensitivity analyses showed robust results and Peter's test showed no publication bias. The results of subgroup analyses for the research type, drugs, and type of brucellosis were largely consistent with the overall outcome indicators, indicating the reliability and robustness of the overall results. CONCLUSIONS In the treatment of brucellosis, triple antibiotics have better efficacy than dual antibiotics and do not increase the incidence of side effects.

Abstract
In this study, we investigated the effects of sodium propionate (SP) treatment on intracellular mechanism of murine macrophages and its contribution to host immunity during Brucella abortus 544 infection. The intracellular growth assay revealed that SP inhibited Brucella replication inside the macrophages. To determine intracellular signaling involved during SP treatment after Brucella infection, we analyzed the change of five different cytokines production relevant to SP such as TNF-α, IL-10, IFN-γ, IL-1β, and IL-6, and the results indicated that the boost with IL-10 was apparent throughout the culture period for 48 h as well as IL-1β which was apparent at 24 h post-infection and IFN-γ which was apparent at 24 h and 48 h in comparison to SP untreated groups. On the other way, SP-treated cells displayed suppressed production of TNF-α and IL-6 at all time points tested and 48 h post-infection, respectively. Furthermore, we conducted western blot to establish a cellular mechanism, and the result suggested that SP treatment attenuated p50 phosphorylation, part of the NF-κB pathway. These findings indicated that the inhibitory effect of SP against Brucella infection could be attributed through induction of cytokine production and interference on intracellular pathway, suggesting SP as a potential candidate for treating brucellosis.

Abstract
Can brucellosis-related biochemical and immunological parameters be used as diagnostic and treatment indicators? The goal of this project was to look at biochemical parameters, trace elements, and inflammatory factors in the acute and chronic stages of brucellosis after treatment with streptomycin and hydroxychloroquine-loaded solid lipid nanoparticles (STR-HCQ-SLN). The double emulsion method was used for the synthesis of nanoparticles. Serum levels of trace elements, vitamin D, CRP, and biochemical parameters were measured in rats involved in brucellosis. The therapeutic effect of STR-HCQ-SLN was compared with that of free drugs. In both healthy and infected rats, serum concentrations of copper, zinc, iron, magnesium, potassium, and biochemical parameters of the liver were significantly different. By altering the serum levels of the aforementioned factors, treatment with STR-HCQ-SLN had a positive therapeutic effect on chronic brucellosis. Vitamin D levels declined (46.4%) and CRP levels rose (from 7.5 mg to less than 1 mg) throughout the acute and chronic stages of brucellosis. This study showed that by comparing the biochemical parameters and the levels of trace elements in the serum of healthy and diseased mice in the acute and chronic stages of brucellosis, it is possible to get help from other routine methods for diagnosis.

Abstract
Bacteria of the genus Brucella are facultative intracellular parasites that cause brucellosis, a severe animal and human disease. Recently, a group of taxonomists merged the brucellae with the primarily free-living, phylogenetically related Ochrobactrum spp. in the genus Brucella. This change, founded only on global genomic analysis and the fortuitous isolation of some opportunistic Ochrobactrum spp. from medically compromised patients, has been automatically included in culture collections and databases. We argue that clinical and environmental microbiologists should not accept this nomenclature, and we advise against its use because (i) it was presented without in-depth phylogenetic analyses and did not consider alternative taxonomic solutions; (ii) it was launched without the input of experts in brucellosis or Ochrobactrum; (iii) it applies a non-consensus genus concept that disregards taxonomically relevant differences in structure, physiology, population structure, core-pangenome assemblies, genome structure, genomic traits, clinical features, treatment, prevention, diagnosis, genus description rules, and, above all, pathogenicity; and (iv) placing these two bacterial groups in the same genus creates risks for veterinarians, medical doctors, clinical laboratories, health authorities, and legislators who deal with brucellosis, a disease that is particularly relevant in low- and middle-income countries. Based on all this information, we urge microbiologists, bacterial collections, genomic databases, journals, and public health boards to keep the Brucella and Ochrobactrum genera separate to avoid further bewilderment and harm.

Abstract
Brucellosis endocarditis is a rare but life-threatening complication of brucellosis, involving congenital, prosthetic and even native valves. Its diagnosis and treatment is a great challenge for doctors. The patient's prognosis requires prompt diagnosis and continuous evaluation of treatment plans to assess the need for either surgical intervention of the infected valves or continuation of antibiotic therapy alone. We present a patient with brucellosis endocarditis, predominantly involving the mitral valve, presenting with vegetations and prolapse of the anterior leaflet of the mitral valve with moderate to severe regurgitation. The patient was treated with triple antibiotic therapy before surgery. After the patient's blood culture results were negative, we removed the infected mitral valve vegetations and performed a mitral valve replacement. The patient was successfully extubated 4 hours after surgery and discharged 11 days after surgery. After discharge, the patient continued to receive triple antibiotic therapy for 2 months and was followed up at the cardiac surgery and infectious disease outpatient clinics.

Abstract
BACKGROUND Brucellosis is an endemic infection affecting the Mediterranean Basin, Arabian Peninsula, India, Mexico, and South America. Data on brucellosis infections in children are limited. OBJECTIVES To review and characterize the clinical presentation of pediatric patients diagnosed with brucellosis in a tertiary medical center. METHODS Retrospective data analysis was conducted on all pediatric patients from January 2010 to December 2020 admitted to the pediatric department with a diagnosis of brucellosis based on a positive serology test or growth of Brucella bacteria in blood culture. RESULTS The study comprised 53 children aged 0-18 years. The mean age at presentation was 11.01 ± 4.91 years; 39 male (73.6%). Pre-infection exposure to unpasteurized milk or unvaccinated livestock was reported in 37 (69.8%). Fever was present in 64.6%, followed by arthralgia (49%), loss of appetite (42.3%), and weight loss (24.6%). Gastrointestinal symptoms were reported in 52.8% and included abdominal pain (34.6%), nausea (28.3%), vomiting (24.5%), and diarrhea (2.6%). Eight patients experienced pancytopenia (15.1%). The median length of intravenous antibiotic treatment was 7 days (range 3-14 days) and for oral antibiotic treatment 6 weeks (range 2-24 weeks). Most patients were initially treated with intravenous gentamycin (90.5%) and long-term oral antibiotics, most commonly doxycycline. Two (3.7%) required admission to the pediatric intensive care unit. No mortality was documented, and all cases of relapses were successfully treated. CONCLUSIONS Pediatric brucellosis is an acute febrile disease often associated with rheumatologic complaints. Patients 8-18 years of age also presented with headache, weight loss, and night sweats.

Abstract
Brucellosis is a multisystemic infection produced by a gram-negative bacillus that can develop a variety of clinical symptoms and complications. Involvement of the central nervous system is a challenging and dangerous consequence of systemic brucellosis. The neurobrucellosis clinical spectrum can be classified as central and peripheral. Meningitis, encephalitis, polyradiculoneuritis, cranial nerve involvement, depression, abscess and cerebrovascular events are some of the potential complications that may develop. The link between neurobrucellosis and cerebrovascular accident has been reported infrequently in the literature. In this report, a case of neurobrucellosis confirmed by cerebrospinal fluid agglutination test and who developed subarachnoid hemorrhage associated with cerebral aneurysm, which is a rare condition in its course was presented. Serum Rose Bengal test and serum Brucella standard tube agglutination (STA) tests were positive at a titer of 1/640 in a 38-year-old male patient who had complaints of fever, sweating, myalgia, arthralgia, weakness, head-neck-back pain and difficulty in walking for 14 days. On magnetic resonance imaging, Brucella sacroiliitis was identified. The patient's fever, head and neck pain continued and nuchal rigidity was found to be positive. Neurobrucellosis was diagnosed based on the cerebrospinal fluid (CSF) examination, which revealed a high white blood cell count, high protein, low glucose level, and STA in CSF at 1/640 titers. Imaging of the brain was conducted concurrently with cerebrospinal fluid analysis indicated subarachnoid hemorrhage caused by cerebral aneurysm rupture. In addition to the medical treatment, the aneurysm rupture was closed with surgical intervention. Three months of simultaneous triple antibiotic treatment were administered to the patient. In the third month of the treatment, the patient was completely cured and no longer had any problems. Although uncommon, subarachnoid hemorrhage due to aneurysm rupture is one of the cerebrovascular consequences of neurobrucellosis. In the process of differential diagnosis of cerebrovascular occurrences, particularly in areas where brucellosis is an endemic disease, it is important to keep in mind that neurobrucellosis can imitate a variety of diseases and cause cerebrovascular events.

Abstract
INTRODUCTION The myriad presentation of osteoarticular brucellosis make the patient seek the help of general practitioners, orthopaedic and rheumatology specialists. Moreover, the lack of disease-specific symptomatology is the leading cause of the delay in diagnosing osteoarticular brucellosis. Given the increasing number of spinal brucellosis cases across the country, no literature is presented on the systematic management of spinal brucellosis. However, with our experience, we formulated a classification for managing spinal brucellosis. METHODS A single-centred prospective observational study was conducted with 25 confirmed cases of spinal brucellosis. Patients were analysed and graded clinically, serologically, and radiologically and were managed with antibiotics for 10-12 weeks, and if necessary, stabilisation and fusion were done based on the treatment classification devised. All patients were followed up to ensure disease clearance at serial follow-up with relevant investigations. RESULTS The mean age of the study participants was 52.16 ± 12.53 years. According to spondylodiscitis severity code (SSC) grading, four patients belong to grades 1, 12 to grade 2 and 9 to grade 3 at presentation. Erythrocyte sedimentation rate (p = 0.02), c-reactive protein (p < 0.001), Brucella agglutination titers (p < 0.001), and radiological outcomes improved statistically by six months. The treatment duration was individualised according to the patient's response to the treatment, with a mean time of 11.42 ± 2.66 weeks. The mean follow-up period was 14.42 ± 8 months. CONCLUSION High index of suspicion of patients from endemic regions, proper clinical assessment, serological evaluation, radiological assessment, appropriate decision-making (medical/surgical) in treatment, and regular follow-up were the key to successful comprehensive management of spinal brucellosis.

Abstract
PURPOSE OF REVIEW Brucellosis is one of the most common zoonosis worldwide, affecting 500 000 people, annually. Neurobrucellosis incidence is approximately 4%, and it is almost always heterogeneous. As there are no typical clinical features, its diagnosis is frequently misdiagnosing by other infections. RECENT FINDINGS Neurobrucellosis picture includes meningitis, meningoencephalitis, encephalitis, cranial neuropathies, intracranial hypertension, sinus thrombosis, hemorrhages radiculitis, peripheral neuropathy, myelitis, and psychiatric manifestations. The diagnosis should be based on symptoms and signs suggestive of neurobrucellosis, not explained by other neurological disease, cerebrospinal fluid analysis, a positive Brucella serology or culture, and a response to specific antibiotics, with a significant improvement of cerebrospinal fluid parameters. SUMMARY Neurobrucellosis can be insidious, and despite its global distribution, it is still unrecognized and frequently goes unreported. The understanding of the current epidemiology is necessary for eradication of the disease in humans, as well as the disease control in animals and prevention based on occupational hygiene and food hygiene.

Abstract
Brucellosis is highly contagious zoonotic bacterial disease caused by gram-negative genus. It has a wide spectrum of clinical manifestations and due to variety and nonspecificity of clinical signs the diagnostics can be very complicated. We present a clinical case of severe chronic brucellosis in a 5-years old boy with long-term course of disease and multiorgan involvement. A different complication of brucellosis including severe syndrome of inappropriate ADH secretion (SIADH) are discussed. Despite severe course of disease patient achieved significant clinical improvement due to multidisciplinary approach and optimal etiotropic and pathogenetic treatment.

Abstract
Gentamicin is used to treat brucellosis, an infectious disease caused by the Brucella species but the drug faces several issues such as low efficacy, instability, low solubility, and toxicity. It also has a very short half-life, therefore, requiring frequent dosing. Consequently, several other antibiotics are also being used for the treatment of brucellosis as a single dose as well as in combination with other antibiotics but none of these therapies are satisfactory. Nanoparticles in particular polymer-based ones utilizing polymers that are biodegradable and biocompatible for instance PLGA are a method of choice to overcome such drug delivery issues and enable potential targeted delivery. The current study focuses on the evaluation of the structural and dynamical properties of a drug-polymer system consisting of gentamicin drug and PLGA polymer nanoparticles in the water representing a targeted drug delivery system for the treatment of brucellosis. For this purpose, all-atom molecular dynamics simulations were carried out on the drug-polymer systems in the absence and presence of the surfactant bis(2-Ethylhexyl) sulfosuccinate (AOT) to determine the structural and dynamical properties as well as the effect of the surfactant on these properties. We also investigated systems in which the polymer constituents were in the form of monomeric units toward decoupling the primary interactions of the monomer units and polymer effects. The simulation results explain the nature of the interactions between the drug and the polymer as well as transport properties in terms of drug diffusion coefficients, which characterize the molecular behavior of gentamicin-polymer nanoparticles for use in brucellosis.

Abstract
BACKGROUND AND OBJECTIVES Qingbutongluo pill (QBTLP), a Chinese herbal preparation, has been developed to treat brucellosis for many years with a good therapeutic effect. This study preliminarily explored its potential molecular mechanisms against brucellosis through network pharmacology. METHODS The active ingredients of QBTLP were screened out mainly from the Traditional Chinese medicine systems pharmacology database and analysis platform (TCMSP), and their potential targets were predicted through the PubChem database and Swiss Target Prediction platform. GeneCards, DisGeNET Digsee and the Comparative Toxicogenomics Database (CTD) searched the targets corresponding to brucellosis. Then, the Venn diagram obtained intersection targets of QBTLP and diseases. Protein-protein interaction (PPI) network analysis was performed using the Search Tool for the Retrieval of Interacting Genes database (STRING) and visualized in Cytoscape software. Module analysis of the PPI network and core target identification was performed using the Molecular Complex Detection (MCODE) and the Cytohubba plugins. The Metascape data platform was used to perform Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis on the intersection targets, and then the "active ingredientstargets- pathways" network was constructed using Cytoscape to screen key active ingredients. RESULTS 19 key active ingredients were identified by network pharmacological, including Baicalein, Cryptopin, etc. The core targets of QBTLP for treating brucellosis contained TNF, TLR4, MAPK3, MAPK1, MAPK8, MAPK14, MMP9, etc. And the main pathways included the Toll-like receptor signaling pathway, NOD-like receptor signaling pathway, TNF signaling pathway, MAPK signaling pathway, Th17 cell differentiation, and IL-17 signaling pathway. CONCLUSIONS This study explored the mechanisms of QBTLP for treating brucellosis, which may provide a scientific basis for the clinical application of QBTLP.

Abstract
BACKGROUND One of the major problems with Brucella infections is its tendency to become chronic and recurrent, providing a hindrance to the management of this infection. It has been proposed that chronicity is greatly affected by a phenomenon called persistence in bacteria. Several mechanisms are involved in bacterial persistence, including the type II toxin-antitoxin system, the SOS and oxidative and stringent responses. METHODS In this in silico study, these persistence mechanisms in Brucella spp. were investigated. RESULTS The structure and the interactions between modules involved in these systems were designed, and novel peptides that can interfere with some of these important mechanisms were developed. CONCLUSION Since peptide-based therapeutics are a new and evolving field due to their ease of production, we hope that peptides developed in this study, as well as the information about the structure and interactions of modules of persistence mechanisms, can further be used to design drugs against Brucella persister cells in the hope of restraining the chronic nature of Brucellosis.

Abstract
BACKGROUND Brucellosis is a multisystem disease with a broad spectrum of non-specific symptoms that generally occur within three weeks but sometimes up to 3 months after inoculation. Human brucellosis is quite uncommon in Elderly in Qatar. CASE REPORT This report describes a case of Brucellosis in acute geriatric unit under Rumailah Hospital in Qatar. The patient was an 81-year-old Qatari Gentle man, functionally able to walk with minimal assistance and had mild cognitive impairment who presented with high-grade fever with chills, anorexia, low back pain and arthralgia for 10 days. The above complaints occurred often for 1 month and had fever intermittently. Lab investigations revealed as high CRP 117 mg/l, low Hb 9.1 g/dl and mild elevation in ALP (151 µ/l) with normal leukocyte and platelet count. His blood culture positive for Brucella melitensis with high brucella Antibody titter 1:1280. The diagnosis made as Brucellosis. DISCUSSION The clinical manifestations of Brucellosis are fever, night sweating, chills, arthralgia and loss of appetite. It seems pyrexia of unknown origin without other symptoms is most common presentation of Brucellosis in old age. The confirmation of Brucellosis made with serological tests, with significantly high titer, in the presence or absence of blood culture. Brucella antibody titers (≥1:160) are suggestive of active infection. Anemia and raised CRP and liver enzymes were the most prominent laboratory abnormalities in our patients. Previous study from Qatar reported that 41.7% had a history of raw milk consumption and 12.5% had a history of animal contact. The objectives of Brucellosis treatment include the prevention of complications and relapse. CONCLUSION Our case presented with classical symptoms and received appropriate treatment on time. However, atypical clinical presentation and lack of specific history taking can delay diagnosis and treatment; it leads to serious clinical disease progression with increased complications. From this case study, we would contribute to optimal assessment and to keep differential diagnosis for unknown cause of fever can be Brucellosis in geriatric population.

Abstract
Brucellosis is one of the most common zoonotic infections with worldwide distribution. The clinical presentation of brucellosis ranges from asymptomatic to severe disease involving haematological, gastrointestinal, neurological and osteoarticular systems. Cardiovascular manifestations are rare in brucellosis cases with endocarditis being the most common presentation. Isolated pericarditis with massive pericardial effusion without endocarditis is extremely rare. Here, we describe a case of brucellosis with sole manifestation of pericarditis with massive pericardial effusion in a patient with end stage renal disease diagnosed based on the isolation of Brucella melitensis from pericardial fluid.

Abstract
Brucellosis, a zoonosis, can cause an inflammatory response in most organs and continues to be a public health problem in some endemic areas, whereas neurobrucellosis is a morbid form of brucellosis that affects the central nervous system (CNS) with poor prognosis. Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy is an autoimmune disease, and there have been no reports of a Brucella infection, leading to GFAP astrocytopathy. We report the case of a patient with a positive and high level of GFAP antibodies in the cerebrospinal fluid (CSF), following a Brucella infection. Although this patient did not show any responsible lesions in the diffusion sequence of the magnetic resonant imaging (MRI) scan, we found an evidence of thoracolumbar (T12) involvement on fluorodeoxyglucose (FDG) positron emission tomography (PET). The symptoms of spinal cord involvement were only partly relieved after initial treatment [doxycycline (0.1 g Bid) and rifampicin (0.6 g Qd) for 6 weeks]; however, they markedly improved after the subsequent immunosuppressive therapy [intravenous methylprednisolone (1,000 mg for 3 days)], followed by a 50% reduction from the preceding dose after 3 days, and subsequently, oral prednisone tablets (60 mg/day) was started, which was then gradually tapered [reduced to 10 mg/day every 1–2 weeks)]. The positive response to immunosuppressive therapy and treatment outcome strongly indicated the presence of an autoimmune neurological disease probably triggered by some infectious factors. Therefore, our findings reveal that a Brucella infection is one of the causes of autoimmune GFAP astrocytopathy, and when this infection is difficult to be identified by regular MRI, FDG PET can be used as a supplementary method for diagnosis and treatment.

Abstract
Brucella infection is often an occupational disease of veterinarians, agricultural workers, and slaughterhouse workers. The infection is generally spread by contact of broken skin (open cuts or wounds) with infected animal tissues or by ingesting unpasteurized milk and dairy products from the infected animals. Brucellosis, which can have many different clinical presentations, may rarely cause joint prosthesis infection. There is not enough literature about the treatment of such infection which should be kept in the differential diagnosis, especially in endemic regions. We aim to present diagnostic and treatment approach of Brucella prosthetic infection in a 70-year woman with total knee arthroplasty. Key Words: Brucella, Prosthesis, Infection, Total knee arthroplasty.

Abstract
Background Human brucellosis caused by the facultative intracellular pathogen Brucella spp. is an endemic bacterial zoonosis manifesting as acute or chronic infections with high morbidity. Treatment typically involves a combination therapy of two antibiotics for several weeks to months, but despite this harsh treatment relapses occur at a rate of 5–15%. Although poor compliance and reinfection may account for a fraction of the observed relapse cases, it is apparent that the properties of the infectious agent itself may play a decisive role in this phenomenon. Methodology/Principal findings We used B. abortus carrying a dual reporter in a macrophage infection model to gain a better understanding of the efficacy of recommended therapies in cellulo. For this we used automated fluorescent microscopy as a prime read-out and developed specific CellProfiler pipelines to score infected macrophages at the population and the single cell level. Combining microscopy of constitutive and induced reporters with classical CFU determination, we quantified the protective nature of the Brucella intracellular lifestyle to various antibiotics and the ability of B. abortus to persist in cellulo despite harsh antibiotic treatments. Conclusion/Significance We demonstrate that treatment of infected macrophages with antibiotics at recommended concentrations fails to fully prevent growth and persistence of B. abortus in cellulo, which may be explained by a protective nature of the intracellular niche(s). Moreover, we show the presence of bona fide intracellular persisters upon antibiotic treatment, which are metabolically active and retain the full infectious potential, therefore constituting a plausible reservoir for reinfection and relapse. In conclusion, our results highlight the need to extend the spectrum of models to test new antimicrobial therapies for brucellosis to better reflect the in vivo infection environment, and to develop therapeutic approaches targeting the persister subpopulation. Brucellosis is a zoonosis endemic to many low- and middle-income countries around the world. Therapies recommended by the WHO are comprised of at least two antibiotics for several weeks, sometimes months. Relapses are frequent despite these harsh treatments. The underlying reasons for these relapses, besides reinfection and non-compliance to treatment, are unknown. Our study shows that Brucella abortus can form so called “persisters” in rich broth but also inside macrophages. This small bacterial subpopulation survives antibiotic treatment and resumes growth after removal of the antibiotics and could therefore serve as a reservoir for relapses in human brucellosis. Furthermore, we show that the intracellular lifestyle of Brucella has protective properties against recommended antibiotics as observed for other intracellular pathogens, highlighting the necessity to develop new infection models to assess antibiotic efficacy.

Abstract
Human brucellosis is one of the most prevalent zoonoses. There are many similarities between the pathogenesis of Mycobacterium tuberculosis (MTB) infection and that of brucellosis. Immune reconstitution inflammatory syndrome (IRIS) may occur during the treatment of MTB infection, but it has not been reported in brucellosis cases thus far. We report the case of a 40-year-old male whose condition initially improved after adequate anti-Brucella therapy. However, 3 weeks later, the patient presented with exacerbation of symptoms and development of a paravertebral abscess. After exclusion of other possible causes of clinical deterioration, immune reconstitution inflammatory syndrome (IRIS) with brucellosis was presumed. After supplementation with anti-Brucella treatment with corticosteroids, the abscess disappeared, and the symptoms completely resolved. Our case suggests that it is necessary to be aware of the possible occurrence of IRIS in patients with brucellosis in clinical practice.

Abstract
In China, 13.3% of human brucellosis cases progressed to chronic disease; serum agglutination test might cause treatment elongation. Serum agglutination test plus exposure history were used to diagnose most cases of human brucellosis in 2 China provinces. After appropriate treatment, 13.3% of acute brucellosis cases progressed to chronic disease; arthritis was an early predictor. Seropositivity can persist after symptoms disappear, which might cause physicians to subjectively extend therapeutic regimens.

Abstract
OBJECTIVE Human brucellosis is a zoonosis with an extremely wide spectrum of clinical manifestations. Focal splenic involvement is very uncommon, particularly in the pediatric age group, during the illness' acute phase. CASE REPORT A 4-year-old boy, already receiving third-generation cephalosporin treatment, was transferred from a local hospital to the University Pediatric Department for fever, anemia, increased inflammation index, and multiple, hyper-echogenic splenic lesions on abdominal ultrasound. Initial diagnostic laboratory investigations for Brucella infection, including the Widal-Wright test, were found to be negative. However, further diagnostic laboratory analysis using the chemiluminescent immunoassay was positive for Brucella IgM antibodies. Treatment with rifampicin at a dose of 150 mg/Kg/twice daily and co-trimethoprim at a dose of 80 mg/Kg/twice daily was started and continued for 7 weeks. IgM antibodies were undetectable after 2 weeks of treatment, and after 6 weeks of treatment, abdominal ultrasound documented a reduction of the diameter of the major splenic infiltrate from 1 to 0.5 cm. At 3 and 5 months of follow-up, re-evaluation of the abdominal lesions displayed complete resolution of the splenic lesions and a complete clinical recovery. CONCLUSIONS The present case and a literature review are presented in this study since a standard diagnostic laboratory evaluation for brucellosis may miss the diagnosis, and in suspected cases, the laboratory analysis should be extended. Splenic abscesses are known to be rare in brucellosis, but the diagnosis should be considered in children with severe focal lesions, as specific antibiotic treatment may result in complete clinical recovery.

Abstract
Neurobrucellosis is a zoonotic infection transmitted by infected animals or by contact with animal products and is an important health problem in resource-limited settings. In this case report, we present the case of a middle-aged man presenting with encephalomyelitis with hearing loss and diagnosed with neurobrucellosis based on imaging and serological tests. Because brucellosis infection is indolent, a high index of suspicion should be maintained in individuals presenting with fever, neurological signs and symptoms so that early management can prevent long-term neurological sequelae such as focal neurological deficits, hydrocephalus and psychiatric sequelae.

Abstract
COVID vaccinations have been an important step in controlling the COVID-19 pandemic. Despite the fact they were generally safe and effective, a few case reports of renal disorders have been published following COVID vaccines. We report a 29-year-old man with history of Chronic Kidney Disease who presented to our center with flank pain after receiving AstraZeneca COVID vaccine. He also had history of raw milk ingestion. His initial investigations showed high creatinine with high level of proteinuria. A renal biopsy was consistent with immune complex-mediated glomerulonephritis on top of renal fibrosis. His brucella serology also showed high titer. He was started on treatment for Brucellosis and planned for follow-up afterwards for further therapy. To the best of our knowledge, this is the first reported case of concomitant Brucellosis and post COVID vaccine glomerulonephritis.

Abstract
Brucellae are intracellular sneaky bacteria and they can elude the host's defensive mechanisms, resulting in therapeutic failure. Therefore, the goal of this investigation was to rapid identification of Brucella species collected from animals and humans in Saudi Arabia, as well as to evaluate their resistance to antibiotics. On selective media, 364 animal samples as well as 70 human blood samples were cultured. Serological and biochemical approaches were initially used to identify a total of 25 probable cultured isolates. The proteomics of Brucella species were identified using the MALDI Biotyper (MBT) system, which was subsequently verified using real-time polymerase chain reaction (real-time PCR) and microfluidic electrophoresis assays. Both Brucella melitensis (B. melitensis) and Brucella abortus (B. abortus) were tested for antimicrobial susceptibility using Kirby Bauer method and the E-test. In total, 25 samples were positive for Brucella and included 11 B. melitensis and 14 B. abortus isolates. Twenty-two out of 25 (88%) and 24/25 (96%) of Brucella strains were recognized through the Vitek 2 Compact system. While MBT was magnificently identified 100% of the strains at the species level with a score value more than or equal to 2.00. Trimethoprim-sulfamethoxazole, rifampin, ampicillin-sulbactam, and ampicillin resistance in B. melitensis was 36.36%, 31.82%, 27.27%, and 22.70%, respectively. Rifampin, trimethoprim-sulfamethoxazole, ampicillin, and ampicillin-sulbactam resistance was found in 35.71%, 32.14%, 32.14%, and 28.57% of B. abortus isolates, correspondingly. MBT confirmed by microfluidic electrophoresis is a successful approach for identifying Brucella species at the species level. The resistance of B. melitensis and B. abortus to various antibiotics should be investigated in future studies.
