Abstract
BACKGROUND Mediastinitis and sternal osteitis are critical complications in cardiac surgery. Cases of these complications caused by Mycoplasma hominis are extremely rare. CASE PRESENTATION We present a case of mediastinitis and sternal osteitis caused by M. hominis infection following ascending aortic replacement surgery. Whole gene sequencing analysis suggested the genitourinary tract as the most likely source of this M. hominis infection. Successful infection control was achieved through a regimen of moxifloxacin treatment. Additionally, a notable correlation was observed between serum levels of interleukin-6 and M. hominis infection. CONCLUSIONS The significance of M. hominis as a potential cause of postoperative infection in cardiac surgery is still not fully recognized. Special attention should be paid to patients with bacteriologically negative infections, as M. hominis should not be disregarded, despite its rarity.

Abstract
BACKGROUND Urogenital Mollicutes, that is, Mycoplasma hominis and Ureaplasma spp., can colonize the urogenital tract. While urogenital colonization is frequent, infections are rare but should not be missed. Furthermore, extragenital infections are even rarer. Over the past years, they have been increasingly documented as a cause of hyperammonemia syndrome (HS) and post-surgical infections. We review the literature on studies focused on post-surgical infections and HS involving urogenital Mollicutes after thoracic surgery including lung (LTR) and heart (HTR) transplantation. METHODS A systematic review was performed by searching PubMed/Medline case reports, case series, cohort studies, and clinical trials. Cases of infections and HS by urogenital Mollicutes after HTR and LTR transplantations were reported. RESULTS Overall, urogenital Mollicutes were associated with 15 HS, 31 infections in HTR and LTR, and 18 post-thoracic surgical infections in another context. Post-surgical infections were reported in all contexts. They were mainly due to M hominis, the only species that could cultivate on standard enriched agar forming pinpoint colonies after 3-5 days of incubation. Microbiologists should be prompted to pinpoint colonies even if the examination of Gram-staining is negative. The patients' management required surgical treatment and antimicrobials, almost always tetracyclines and/or fluoroquinolones. Conversely, HS occurred almost exclusively in bilateral LTR and is more likely due to Ureaplasma spp. As Ureaplasma spp. do not cultivate on standard media, the microbiological diagnosis was performed using molecular methods. CONCLUSIONS Infections involving urogenital Mollicute should be considered in LTR with HS. The overall rate of mortality is high and might be due in part to delay in etiologic diagnosis. Post-surgical infections were reported in all contexts. The route of contamination with Mollicutes remains unknown in HTR and non-transplant surgery, but evidence of transmission from donors has been documented for LTR.

Abstract
Mycoplasma hominis, a commensal bacterium that commonly inhabits the genital tract, leading to infections in both the genitourinary and extragenital regions. However, the antimicrobial resistance and pathogenic mechanisms of M. hominis isolated from extra-urogenital cystic abscess is largely unknown. This study reports the genomic epidemiological characteristics of a M. hominis isolate recovered from a pelvic abscess sample in China. Genomic DNA was extracted and sequenced using Illumina HiSeq X Ten platform. De novo assembly was performed and in silico analysis was accomplished by multiple bioinformatics tools. For phylogenomic analysis, publicly available M. hominis genomes were retrieved from NCBI GenBank database. Whole genome sequencing data showed that the genome size of M. hominis MH4246 was calculated as 679,746 bp, with 558 protein-coding sequences and a G + C content of 26.9%. M. hominis MH4246 is resistant to fluoroquinolones and macrolides, harboring mutations in the quinolone resistance-determining regions (QRDRs) (GyrA S153L, ParC S91I and ParE V417I) and 23S rRNA gene (G280A, C1500T, T1548C and T2218C). Multiple virulence determinants, such as tuf, hlyA, vaa, oppA, MHO_0730 and alr genes, were identified. Phylogenetic analysis showed that the closest relative of M. hominis MH4246 was the strain MH-1 recovered from China, which differed by 3490 SNPs. Overall, this study contributes to the comprehension of genomic characteristics, antimicrobial resistance patterns, and the mechanisms underlying the pathogenicity of this pathogen.

Abstract
BACKGROUND Mycoplasma hominis is a facultative anaerobic bacterium commonly present in the urogenital tract. In recent years, M. hominis has increasingly been associated with extra-urogenital tract infections, particularly in immunosuppressed patients. Detecting M. hominis in a diagnostic laboratory can be challenging due to its slow growth rate, absence of a cell wall, and the requirements of specialized media and conditions for optimal growth. Consequently, it is necessary to establish guidelines for the detection of this microorganism and to request the appropriate microbiological work-up of immunosuppressed patients. CASE PRESENTATION We hereby present two cases of solid organ transplant patients who developed M. hominis infection. Microscopic examination of the bronchial lavage and pleural fluid showed no microorganisms. However, upon inoculating the specimens onto routine microbiology media, the organism was successfully identified and confirmation was performed using 16S rDNA sequencing. Both patients received appropriate treatment resulting in the resolution of M. hominis infection. CONCLUSIONS The prompt detection of M. hominis in a clinical specimen can have a significant impact on patient care by allowing for early intervention and ultimately resulting in more favorable clinical outcomes, especially in transplant patients.

Abstract
Background Mycoplasma hominis, Ureaplasma parvum, and Ureaplasma urealyticum are commensal bacteria that are associated with colonization and infection of the urogenital tract. However, colonization of the respiratory tract by these microorganisms in adults has not been fully investigated. Methods Urine and respiratory tract samples (sputum, tracheal aspirates, and bronchoalveolar lavage) of patients aged 20-80 years were analyzed to detect the presence of M. hominis, U. parvum, and U. urealyticum using a conventional PCR method. The samples were submitted to the microbiological clinical laboratory of Hiroshima University Hospital from December 1, 2021 to May 31, 2022. Results In total, 334 urine and 238 respiratory tract samples were analyzed. The overall detection rates of M. hominis, U. parvum, and U. urealyticum were 2.9%, 1.7%, and 2.3% in male urine; 7.0%, 13.8%, and 1.9% in female urine; 2.2%, 0%, and 2.2% in male respiratory tract; and 0%, 2.0%, and 0% in female respiratory tract, respectively. In urine samples, the detection rates of M. hominis, U. parvum, and U. urealyticum were significantly higher (p < 0.001) for women (29/159; 18.2%) than for men (10/175; 5.7%); however, in respiratory tract samples, the detection rates were not significantly different (p = 0.70) between women (2/101; 2.0%) and men (5/137; 3.7%). Further, both the urine and respiratory samples of 83 patients were analyzed. Three male samples were positive for M. hominis or U. urealyticum, and M. hominis and U. urealyticum were matched in both the urine and respiratory tract samples: M. hominis (n = 1), U. urealyticum (n = 1), M. hominis + U. urealyticum (n = 1). Conclusion M. hominis, U. parvum, and U. urealyticum were detected in the respiratory tract of not only the young patients, but also of patients aged 50-60 years. Further studies are required to understand the relationship of these microorganisms in urogenital and respiratory tract samples with extra-genital infections.

Abstract
Mycoplasma hominis is associated with various infections, for which the treatment can be complex. Lipoic acid (LA) plays a role as a cofactor in eukaryotes, most Bacteria, and some Archea. Research of recent years has increasingly pointed to the therapeutic properties of exogenously supplemented LA. The present study was conducted on 40 strains of M. hominis cultured with the following LA concentrations: 1,200 μg/ml, 120 μg/ml, and 12 μg/ml. The bacterial colonies of each strain were counted and expressed as the number of colony-forming units/ml (CFU). The number of CFU in M. hominis strains obtained in the presence of LA was compared with the number of CFU in the strains grown in the media without LA. The obtained results indicated that the presence of LA in the medium did not affect the growth of M. hominis. The investigation of the influence of LA on the growth and survival of microbial cells not only allows for obtaining an answer to the question of whether LA has antimicrobial activity and, therefore, can be used as a drug supporting the treatment of patients infected with a given pathogenic microorganism. Such studies are also crucial for a better understanding of LA metabolism in the microbial cells, which is also important for the search for new antimicrobial drugs. This research is, therefore, an introduction to such further studies.

Abstract
BACKGROUND Mycoplasma hominis is a human commensal bacterium of the urogenital tract, and extragenital infection caused by M. hominis has rarely been reported. The identification of M. hominis is challenging, and surgeons are generally not aware that this bacteria can cause postoperative infection. Here, we report a rare case of postoperative mediastinitis caused by M. hominis after cardiac surgery in an immunocompetent patient. CASE PRESENTATION A 54-year-old man presented with pain and purulent discharge from the wound after aortic valve replacement and patent foramen ovale closure. However, Gram staining and culture of bacteria from the purulent discharge was negative, and empiric sulbactam/ampicillin therapy was not effective. This patient developed mediastinitis and rupture of a pseudoaneurysm of the ascending aorta caused by mediastinitis, and re-operation was performed. Then, postoperative mediastinitis caused by M. hominis or Ureaplasma species was suspected and bacterial cultures targeting these pathogens were performed. M. hominis was identified from abscess and tissue obtained from the surgical site and urine. A final diagnosis of postoperative mediastinitis caused by M. hominis was determined. The patient was initially treated with levofloxacin and then with minocycline for 3 weeks. The patient's clinical condition improved; the patient was transferred to another hospital. CONCLUSION The role of M. hominis as a cause of postoperative infection might be underestimated in cardiac surgery. M. hominis should be considered when culture-negative purulent discharge is observed or there is no response to standard empiric treatment of postoperative infections.

Abstract
BACKGROUND Resistance to tetracyclines, the first-line treatment for urogenital infections caused by Mycoplasma hominis and Ureaplasma species, is increasing worldwide. The aim of the present study was to determine the global status of resistance to this class of antibiotics. METHODS Electronic databases were searched using keywords including 'Mycoplasma', 'Mycoplasma hominis', 'M. hominis', 'Ureaplasma', 'Ureaplasma urealyticum', 'Ureaplasma parvum', 'U. urealyticum', 'U. parvum', 'Ureaplasma species', 'resistance', 'antibiotic resistance', 'antibiotic susceptibility', 'antimicrobial resistance', 'antimicrobial susceptibility', 'tetracycline', 'doxycycline' and 'minocycline'. Finally, after some exclusions, 37 studies from different countries were included in the study and meta-analysis was performed on the data collected. RESULTS The midrange resistance rates for M. hominis and U. urealyticum/parvum to tetracycline, doxycycline and minocycline were 50.0%, 9.0% and 16.7% and 43.3%, 28.6% and 9.0%, respectively. A high level of heterogeneity was observed in all studies (I2 > 50%, P value < 0.05), except those representing doxycycline resistance in M. hominis isolates (I2 = 39.1%, P = 0.02). No evidence of publication bias was observed in the studies and neither Egger's test nor Begg's test showed significant publication bias. CONCLUSIONS The results of the present study show that the overall resistance to tetracyclines is relatively high and prevalent among M. hominis and Ureaplasma species throughout the world. This highlights the importance of and necessity for regional and local antibiotic susceptibility testing before treatment choice as well as development of newer generations of tetracyclines to prevent antibiotic misuse, emergence and spread of resistant strains and, finally, the failure of treatment.

Abstract
BACKGROUND Hip replacement is generally conducted in those with prolonged arthritis pain or hip fractures, and postoperative infection is a serious complication. Mycoplasma hominis, belonging to mycoplasma species, exists mainly in the genitourinary tract. M. hominis infection after total hip replacement was rarely documented in literature. CASE PRESENTATION A 59-year-old male was febrile after left total hip replacement. Empiric therapy with cefepime for suspected infection was ineffective. Specimens at the infection site were collected for culture, and pinpoint colonies grew after incubation at 35 °C for 48 h on blood agar plate. They grew to approximately 0.5 mm colonies in diameter after 7-day incubation, and were identified as M. hominis. Sequentially, combination therapy with clindamycin hydrochloride and moxifloxacin was initiated, and the patient defervesced within 3 days and was discharged home. CONCLUSIONS The study highlighted the potential pathogenicity of M. hominis in postoperative infection. The possibility of this microorganism involvement should be valued if the patients who experienced the hip or joint replacement had inexplicable fever.

Abstract
PURPOSE Mycoplasma hominis is considered among the causes of urogenital infections and shows increasing resistance to fluoroquinolones. However, data regarding the fluoroquinolone resistance mechanism of M. hominis in Southwest China are limited. This study aimed to investigate gene mutations of quinolone resistance-determining regions (QRDRs) of M. hominis isolated from clinical urogenital samples in a Chinese hospital. METHODOLOGY Strains of M. hominis were identified by 16S rRNA gene sequencing. The minimal inhibitory concentrations (MICs) of fluoroquinolones were determined by the broth microdilution method, following CLSI guidelines. PCR was used to amplify the QRDRs of the genes gyrA, gyrB, parC and parE. Positive products were sequenced, and gene mutations and amino acid substitutions were analysed by DNAMAN software and BLAST. RESULTS The resistance rates of M. hominis to ciprofloxacin (CIP), levofloxacin (LVX), moxifloxacin (MXF) and gatifloxacin (GAT) were 90.5, 85.7, 73.8 and 71.4 %, respectively. A total of 57 isolates of M. hominis were screened, among which 52 strains demonstrated different resistant phenotypes to fluoroquinolones, 41 harboured amino acid substitutions of GyrA S153L, 51 harboured ParC S91I and 22 harboured ParC K144R. ParE A463S and ParC A154T were recorded for the first time and no amino acid change was detected in GyrB. CONCLUSION The resistance of M. hominis to fluoroquinolones in Southwest China is mainly related to mutations in QRDRs of either gyrA or parC. High-level resistance is associated with mutations in both DNA gyrase and topoisomerase IV.
