Abstract
Background Tuberculosis (TB) continues to be a global health problem. While childhood TB contributes 10% to the global TB burden, the paucibacillary nature of TB disease in children and the absence of reliable diagnostic methods have made MTB diagnosis in children to be a great challenge. This study aimed to determine the prevalence of MTB and rifampicin-resistant MTB (RR-MTB) among children using Gene Xpert MTB/RIF Assay in Tigray, Ethiopia. Methods A retrospective database study was conducted among children in ten governmental hospitals in the Tigray region. Gene Xpert MTB/RIF results of sputum/gastric lavage samples from children with presumptive TB from January 2016 to December 2019 were extracted using a data extraction sheet. Data were collected and analyzed using Statistical Package for the Social Sciences version 21. Results The prevalence of bacteriologically confirmed MTB by Gene-Xpert in children with presumptive TB was 7.3% (95% CI: 6.7%-7.9%) and the proportion of those that were Gene-Xpert MTB positive who also have rifampicin resistance was 10.9% (95% CI: 8.2-13.6%). Older children aged 11-15 years [AOR = 1.76; 95% CI = 1.33-2.33, p < 0.001] and adolescents 16-17 years [AOR = 2.18; 95% CI = 1.63-2.92, p < 0.001] were more likely to be MTB positive. Relapse cases [AOR = 1.66; 95% CI = 1.09-2.51, p = 0.017] and lost/failure cases [AOR = 8.82; 95% CI = 3.94-19.76, p < 0.001] were more likely to have MTB compared to the new cases. Conclusion The proportion of MTB-positive among the TB presumptive patients was 7.3%. The proportion of rifampicin-resistant TB to all positive patients was 10.9%. Female participants had more MTB than males (or younger children). The result highlights the need for due attention in children because it is very helpful in determining the future control of the disease.

Abstract
Background In Ethiopia, salmonellosis is one of the most common zoonotic and foodborne illnesses. Ethiopia continues to be at risk for its fast-expanding medication resistance. For the development of preventative and control methods, summarized knowledge regarding salmonellosis is necessary. Determining a thorough evaluation of the prevalence, serotypes, and antibiotic resistance of Salmonella in humans and animals from January 1, 2010, to December 30, 2022, in Ethiopia was our goal. Methods To find Salmonella related articles that published in English, we used the Google Scholar and PubMed search engines. Three researchers conducted the eligible studies using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, making sure to include the necessary keywords. If studies were duplicates, incomplete publications, or reported without an antimicrobial test were excluded. Excel 2013 was used to calculate frequencies and tabulate data. Results There were a total of 43 investigations from food handlers, diarrhoeic patients, and animals. The prevalence rates ranged from 1% to 10% and 1% to 13% among food handlers and diarrhoea patients, respectively. The highest prevalence was among pigs (41.6%). S. Anatum in animals and S. Typhimurium in people were the predominant serotypes. Amoxicillin and ampicillin were claimed to be 100% resistant in human studies. The highest recorded resistances for ceftriaxone and ciprofloxacin were 16.7% and 100%, respectively. Animal studies revealed that Salmonella resistances to ampicillin, streptomycin and tetracycline were 100%, 90%, 86.4%, respectively. S. Kentucky showed complete resistance to tetracycline, ampicillin, gentamicin, ciprofloxacin, and streptomycin. Conclusion The prevalence of Salmonella among asymptomatic food handlers, diarrheal patients and animals were high in Ethiopia. S. Typhimurium that have the zoonotic importance was presented predominantly in human study. High levels of resistances were showed to tetracycline, ampicillin and streptomycin in animal studies. Salmonellosis prevention and control techniques should be strengthened.

Abstract
Background Little is known about bacteria that produce extended-spectrum beta-lactamases (ESBLs) and carbapenemase in patients with urinary tract infections (UTIs) in Tigrai, Ethiopia. The aim of this study was to describe the magnitude of ESBL- and carbapenemase -producing gram-negative bacteria among patients suspected of community- and hospital-acquired UTIs at a referral hospital in Tigrai, Ethiopia. Methods A cross-sectional study was conducted at Ayder Comprehensive Specialized hospital from January 2020 to June 2020. A 10-20 mL sample of morning mid-stream and catheter urine was collected from consenting participants. Urine samples were cultured on cysteine lactose electrolyte deficient medium and MacConkey agar, and bacteria were identified using standard microbiological protocols. The Kirby-Bauer disk diffusion method was used for antimicrobial susceptibility testing. The combination disk and modified Hodge tests were used detect ESBL and carbapenemase production, respectively. The data was entered into EPI 3.1 software and analyzed using SPSS version 21. Results Overall, 67 gram-negative bacteria were recovered from 64 participants. Escherichia coli was the predominant isolate (68.6%), followed by Klebsiella pneumoniae (22.4%), while ESBL production was found in both Escherichia coli and Klebsiella pneumoniae (52.2% and 86.7%, respectively). Isolates recovered from patients with hospital-acquired UTIs were more likely to produce ESBLs (AOR= 16.2; 95% CI: 2.95-89.5). Carbapenemase was produced by 4.3% of E. coli and 20% of Klebsiella pneumoniae isolates. High resistance rates were found against tetracycline (84.8%), ampicillin (78.3%), amoxicillin/clavulanic acid (58.7%) for Escherichia coli isolates and against ampicillin (93.3%), sulphamethexazole trimethoprim (93.3%), cefotaxime (86.6%), and ceftazidime (86.6%), and tetracycline (73.3%) for Klebsiella pneumoniae. Conclusion Most UTIs were caused by ESBL-producing bacteria, especially those that were related to healthcare. Microbiological-based therapy for patients with UTIs is essential at our study site due to high rates of ESBL and significant carbapenemase production with concomitant high rates of drug resistance to several antibiotics.

Abstract
Background Globally, Neisseria gonorrhoeae is the second most common cause of bacterial sexually transmitted diseases. The prominent predicament of this bacterium is its complications, non-susceptibility for many drugs, and aggravated transmission of other sexually transmitted infections. There is limited information about the prevalence, antibiotic resistance, and risk factors of N. gonorrhoeae in Tigrai, Ethiopia. Therefore, we aimed to determine the prevalence, antibiotic resistance, and risk factors of N. gonorrhoeae among patients attending non-profitable private clinics in Mekelle, Tigrai, Ethiopia. Methods A cross-sectional study among 229 patients was conducted from February to June 2018. The socio-demographic data and associated factors were gathered using structured questionnaire, and swabs were taken from urethra and cervix of males and females, respectively. Specimens were inoculated on standard bacteriological culture media and antibiotic susceptibility testing was performed using Kirby-Bauer disc diffusion technique following the Clinical and Laboratory Standard Institute. Data were analyzed using Statistical Package for Social Sciences Version 21. The level of significance at p-value <0.05 was considered statistically significant. Results The overall prevalence of N. gonorrhoeae was 23 (10.04%). High prevalence rates of N. gonorrhoeae were observed in females, urban residents and married ones. N. gonorrhoeae had shown statistically significant association with HIV positive, previous history of STIs, shisha users, Khat (Catha edulis) users, condom non-users and having more than two sexual partners. All isolates showed resistance to penicillin followed by tetracycline 16 (69.6%) and ciprofloxacin 8 (34.8%). Four isolates (7.4%) exhibited resistance to azithromycin with no resistance to ceftriaxone. Twelve (52.2%) isolates showed multidrug resistance (MDR). Conclusions The prevalence of N. gonorrhoeae and drug resistance, including multidrug resistance, was high in the study. Multiple factors were associated with the acquisition of N. gonorrhoeae. Therefore, behavioral change and communication should be strengthened.

Abstract
Background Hepatitis B and C viruses are important health and socioeconomic problem across the globe, with a remarkable number of diseases and deaths in sub-Saharan African countries. The burden of hepatitis is unknown in the prison settings of Tigrai. Therefore, we aimed to describe the seroprevalence and associated factors of hepatitis B and C viruses among prisoners in Tigrai, Ethiopia. Methods A cross-sectional study was carried out from February 2020 to May 2020 at the prison facilities of Tigrai. Demographics and associated factors were collected from 315 prisoners prospectively. Five milliliters of blood was collected and tested using rapid tests kits of HBsAg (Zhejiang orient Gene Biotech Co., Ltd., China) and HCV antibodies (Volkan Kozmetik Sanayi Ve Ticaret Ltd. STI, Turkey). Positive samples were confirmed using enzyme-linked immunosorbent assay (ELISA) (Beijing Wantai Biological Pharmacy Enterprise Co. Ltd). Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 20 and p<0.05 was considered statistically significant. Results The overall seroprevalence of HBV and HCV were 25 (7.9%) and 1 (0.3%), respectively. The majority of hepatitis B viral infections were identified from the age groups of 18-25 years (10.7%) and unmarried prisoners (11.8%). Prisoners greater than 100 per cell (AOR=3.95, 95% CI=1.15-13.6, p=0.029) and with a history of alcohol consumption (AOR=3.01, 95% CI=1.17-7.74, p=0.022) were significantly associated with HBV infections. Conclusion The seroprevalence of HBV among prisoners was nearly high or borderline (7.9%) with a very low HCV prevalence (0.3%). HBV was most prevalent among young adults, those housed with a large number of prisoners per cell, and those who had a history of alcohol consumption. This study recommends that there should be prison-focused intervention, including regular health education, with the emphasis on the mode of transmission and introducing HBV screening policy for prisoners, especially when they enter the prison.

Abstract
Background Sputum culture conversion status is a cardinal index of treatment response and patient outcome for MDR TB patients on longer anti-TB drugs. But, there is limited information on time to sputum culture conversion of MDR TB patients on a longer anti-TB treatment regimen. Therefore, this study aimed to evaluate time to sputum culture conversion and its predictors among MDR TB patients in Tigray, Northern Ethiopia. Methods A retrospective cohort study was conducted from January 2017 through September 2020 among MDR TB patients in Tigray, Northern Ethiopia. Demographic and clinical characteristics including bacteriological data were extracted from the TB registration book and electronic database in Tigray Health Research Institute. Statistical analysis was performed using SPSS version 25. The time to initial sputum culture conversion was analyzed using the Kaplan-Meier method. Bivariate and multivariate Cox proportional hazards regression analyses were used to identify predictors for culture conversions. P <0.05 was considered statistically significant. Results A total of 294 eligible study participants with a median age of 30 years (IQR: 22.75-40) were included. The participants were followed for a total of 1066.7 person months. Sputum culture conversion was achieved in 269 (91%) of the study participants. The median time of sputum culture conversion was 64 days (IQR: 49-86). In our multivariate model, HIV-positive (aHR=1.529, 95% CI: 1.096-2.132, P=0.012), patients new to anti-TB treatment (aHR=2.093, 95% CI: 1.100-3.982, P=0.024) and baseline AFB smear grading of +1 (aHR=1.982, 95% CI: 1.428-2.750, P=0.001) significantly affected time to initial sputum culture conversion. Conclusion The median time of culture conversion was 64 days. Moreover, the majority of the study participants achieved culture conversion within the first six months of treatment commencement, which supports predefined standard treatment durations.

Abstract
BACKGROUND Infants infected during pregnancy or while breastfeeding requires early HIV diagnosis at 6 weeks after birth to identify HIV infection and timely treatment. The objective of this work was to determine the prevalence and associated risk factors of HIV among HIV exposed infants in the Tigray regional state, Northern Ethiopia. METHODS A cross-sectional study was conducted on 350 exposed infants born to HIV seropositive mothers from September 01 to December 30, 2016. Convenient consecutive sampling technique was employed to enroll HIV exposed infants from age 6 weeks to 18 months attending prevention of mother to child transmission (PMCT) clinic at Anti Retroviral Therapy (ART) site facility in Tigray, Ethiopia. Sociodemographic data and associated risk factors were collected using a structured questionnaire. Dried Blood Spot (DBS) samples were collected from each infant and transported by post to Tigray Health Research Institute to detect HIV infection using real-time Polymerase Chain Reaction (PCR). Data were entered into EPI Info version 7, exported and analyzed using Statistical Package for Social Sciences (SPSS) version 22. p-value less than 0.05 was deemed to be statistically significant by Fisher's exact test. RESULTS Three hundred forty infants (175 males, 165 females) met the criteria for selection during the completion of the study and the overall HIV prevalence was found to be 2.1% (n = 7). The majority of infants were from urban areas (n = 246, 72.4%). 45.5% (5/11, p = 0.001) infants were without ARV prophylaxis, 60% (3/5, p = 0.001) infants born to mothers who did not take maternal PMTCT intervention, 43% (3/7, p = 0.001) infants born to mothers who were not enrolled to ART care, and 6.1% (4/66, p = 0.029) infants of unmarried mothers showed statistically significant difference. CONCLUSIONS The overall prevalence of HIV among exposed infants was high but lower than the Millennium Development Goal targets. In order to eliminate the mother to child HIV transmission (MTCT) ARV prophylaxis in infants must be strengthened, and enrollment of HIV positive pregnant women to PMTCT and ART care and treatment is needed.

Abstract
Objective To assess the enteric bacteria, methicillin resistant S. aureus and antimicrobial susceptibility patterns from buses surfaces in Mekelle, Tigray, Ethiopia. Results A total of 300 swab samples were collected from the handle surfaces of the six city buses. The bacterial isolates revealed from the swab samples were E. coli, Enterobacter spp. and S. aureus. The overall positivity rates of E. coli, Enterobacter spp. and S. aureus were 8 (4%), 4 (1.3%) and 54 (18%) respectively. Methicillin resistant S. aureus was seen in 17 (5.7%) of the total 300 swab samples collected and 17 (31.5%) of the S. aureus isolates. All (100%) of the isolates of E. coli and Enterobacter spp. showed resistance for ampicillin and three-fourth of the isolates of E. coli and Enterobacter spp. displayed resistance for chloramphenicol (75%). Five antimicrobials (ampicillin, chloramphenicol, tetracycline, ciprofloxacin, and cotrimoxazole) have showed resistant for one isolate of E. coli. Likewise four antimicrobials (ampicillin, chloramphenicol, ciprofloxacin, and cotrimoxazole) have revealed resistant for one isolate of Enterobacter spp. Moreover, three isolates of S. aureus were also found resistance to four antibiotics.

Abstract
Objective The objective of this study was to determine the prevalence of methicillin-resistant Staphylococcus aureus and antimicrobial susceptibility patterns among janitors working at Mekelle University, Tigray, Northern Ethiopia. Result The overall prevalence of S. aureus and MRSA in the present study were 17.97% (69/384) and 6.25% (24/384) respectively. Although not statistically significant, the prevalence of MRSA among janitors working in the medical area (9.7%, 10/103) was two times higher than the non-medical area (4.9%, 14/281). Janitors who had more service year and who were unable to read and write were found with high isolates of MRSA. Nasal carriage of MRSA among janitors who work in the hospital and who were hospitalized in the last 3 months and those who had exposure to wastes and body fluids were 13 (37.1%) and 10 (38.5%) respectively. Majority of the isolates of S. aureus were sensitive to ciprofloxacin (67; 97%), doxycycline (56; 81%), erythromycin (54; 78%), chloramphenicol (50; 72.5%) and cefoxitin (45; 65.2%). Sixty-seven of the 69 (97%) were resistant to penicillin. Of the 69 isolates of S. aureus, 22 (31.9%) showed multidrug resistant. Fourteen were resistant to three antimicrobials, 2 were resistant to four antimicrobials, and 7 were resistant to five antimicrobials.

Abstract
Objective The aim of this study was to determine nasal carriage, risk factors and antimicrobial susceptibility pattern of methicillin resistant Staphylococcus aureus among health care-workers of Adigrat and Wukro hospitals Northern Ethiopia. Results The overall prevalence of S. aureus and methicillin resistance S. aureus (MRSA) in the present study were 12% (29/242) and 5.8% (14/242) respectively. The rate of MRSA among S. aureus was 48.3%(14/29). In this study, MRSA carriage was particularly higher among nurse professionals (7.8%) and surgical ward (17.1%). None of the MRSA isolates were sensitive to penicillin and ampicillin. However, low resistance was found for chloramphenicol and clindamycin. Being diabetic and use of hands rub was statistically significant with MRSA colonization.

Abstract
Hepatitis B virus infection is one of the leading causes of liver disease in the world. This study was conducted to determine the prevalence of HBV infection and associated risk factors among pregnant women in Northern Ethiopia using a cross-sectional study design. A total of 328 pregnant women were included in this study. Clinical and socio-demographic data of the pregnant women were collected using a structured questionnaire by nurses or midwives during their ANC visit. For the detection of HBsAg, 5 mL of venous blood was collected from the pregnant women; serum was separated in the health facilities from the whole blood and was transported to Tigray Public Health Research Institute for analysis using. The data were analyzed using SPSS software version 20.0. (IBM). Association of variables with HBV infection was determined with multivariate analysis and P < 0.05 was considered statistically significant. The mean age of the study participants was 25.45 ± 5.067. The overall prevalence rate of HBV infection among the pregnant women was 5.5%. A statistical association of HBV infection with risk factors was seen on participants, who were making unprotected sexual practices with multiple partners (AoR = 6.4, 95%CI, 2-21, P = 0.03), on those who had HBV-infected person in their family (AoR = 8, 95%CI, 1-58, P = 0.02), and on those who had undergone surgical procedures (AoR = 6.8, 95%CI, 1-32, P = 0.022).

Abstract
Background Shigella, gram negative bacterium, is responsible for Shigellosis/bacillary dysentery. It is a global concern although it predominates in developing countries. These are Shigella dysenteriae, Shigella flexneri, Shigella boydii and Shigella sonnei. Drug resistance by Shigella species is another headache of the world. Therefore; this study aimed to review distribution of Shigella Serogroups and their antimicrobial patterns carried out in Africa, Asia and South America. Methods A literature search was performed to identify published studies between January 2001 and December 2014. Published studies were identified using an initial search of the MEDLINE/Index Medicus Database, PubMed, Project Management Consultant, Google Scholar, Science Direct, BioMed Central and Index Copernicus. Results Shigella flexneri was isolated predominately from seven studies in four African countries and eight studies in five Asian countries. The countries in which eligible studies carried out were Ethiopia, Kenya, Eritrea and Ghana in Africa and Pakistan, Iran, China, Nepal and India in Asia. S. sonnei was isolated predominately from one study in Africa, four in Asia and two South America. The countries in which eligible studies carried out were Ethiopia from Africa, Thailand, Vietnam and Iran from Asia and Chile and Trinidad from South America. S. dysentery was also reported majorly from one eligible study in Egypt and one in Nepal. S. boydii did not score highest prevalence in any one of the eligible studies. Three studies from Africa, five from Asia and one from South America were reviewed for antimicrobial resistance patterns of Shigella Serogroups. In all the regions, Ampicillin developed highly resistance to almost all the Serogroups of Shigella whereas all the strains were sensitive to Ciprofloxacin. Conclusion The incidence of Shigella Serogroups in the selected three regions is different. The domination of S. flexneri is observed in Africa and Asia although S. sonnei in South America is dominant. Shigella Serogroups are becoming resistance to the commonly prescribed antimicrobial drugs in developing countries.

Abstract
BACKGROUND Shigellosis is recognized as a major global public health problem especially in developing countries particularly in children under-5 years of age. Therefore; the objective of this study was to determine the prevalence of Shigella among diarrheic children under-5 years of age attending at Mekelle health center, north Ethiopia. METHODS A cross-sectional study was conducted among diarrheic children under-5 years of age from March to May, 2012. Structured questionnaire was used to collect the data. Study participants were recruited by convenience sampling technique. Shigella was isolated and identified using standard bacteriological techniques. RESULTS A total of 241 study participants were included in the study. The overall prevalence of Shigella in this study was 13.3% (32/241). High prevalence of Shigella (22.6%) was revealed from the age group of 12-23 months. No Shigella was isolated from the age group of 0-5 months. Majority of the isolates of Shigella were from bloody and mucoid diarrhea. CONCLUSION There was high prevalence of Shigella infection in this study. Children among the age group of 12-23 months were highly affected. Therefore; responsible bodies should work hard on preventive measures to reduce or eradicate the problem occurred due to shigellosis.
