Ureaplasma urealyticum and Mycoplasma hominis have important role among the causative agents of sexually transmitted diseases. Aim: The aim of the study was to determine the frequency and antibiotic resistance of Ureaplasma urealyticum and Mycoplasma hominis in genital samples obtained from patients examined in the Sexually Transmitted Diseases Centre of the Department of Dermatology, Venerology and Dermatooncology, Semmelweis University, Budapest between May 1, 2008 and July 31, 2010. Patients and methods: Samples were taken from the urethra in men and from the cervix and urethra in women by universal swab (Biolab®) into Urea-Myco DUO kit (Bio-Rad®) and were incubated for 48 hours at 37 C°. Antibiotic sensitivity of positive samples was determined in U9 bouillon using SIR Mycoplasma kit (Bio-Rad®). Results: Samples for 4154 patients aged 16-60 years were examined. In 247/4154 samples (6%) U. urealyticum and in 26/4154 samples (0.63%) M. hominis was isolated from the genital tract. Most U. urealyticum and M. hominis strains (75% and 77%, respectively) were cultured from cervix, while the remaining 25%, and 23% from the male and female urethra, respectively. U. urealyticum and M. hominis were most commonly detected in patients aged between 21 and 40 years. The majority of U. urealyticum strains were sensitive to tetracycline (94%), doxycycline (95%), azithromycin (88%) and josamycin (90%), but were resistant to ofloxacin (21%), erythromycin (85%) and clindamycin (79%). Seventy-seven percent of the U. urealyticum strains were simultaneously resistant to erythromycin and clindamycin, suggesting that ex iuvantibus therapies may select cross-resistant strains to both antibiotics. The resistance of M. hominis to clindamycin, doxycycline, ofloxacin and tetracycline varied between 4% and 12 %. Conclusions: Because none of the strains was sensitive to all examined antibiotics, the antibiotic sensitivity of U. urealyticum and M. hominis strains should be determined. The high rate of ofloxacin, erythromycin and clindamycin resistance should be considered in the therapy of U. urealyticum infections in Hungary. This is the firstsuch a clinical microbiological study in this topic in Hungary. Orv. Hetil., 2011, 152, 1698–1702.

The aim of this study was to estimate the Ureaplasma urealyticum and Mycoplasma hominis infection prevalence and antibiotic resistance levels in gynecological outpatients. Clinical characteristics and laboratory data of gynecological outpatients of the Fourth People’s Hospital of Chongqing from 2015 to 2018 were retrospectively analyzed. Antibiotic resistance levels in U. urealyticum and M. hominis were defined by a commercial Mycoplasma kit for antibiotic susceptibility testing. Univariate analysis and multivariate logistic regression analysis were performed to evaluate risk factors associated with Mycoplasma isolation. Comparisons of yearly distributions and resistance rates were assessed by chi-square tests. Fifty-six percent of gynecological outpatients were positive for U. urealyticum, and 11.02% were positive for M. hominis. In the univariate analysis, women aged 30–39 years or with a history of pregnancy or gynecological diseases had an increased risk for Mycoplasma isolation, while women who were postmenopausal or had an education level of undergraduate degree or above had a decreased risk of Mycoplasma isolation. In the multivariate logistic regression model, an independent risk factor for Mycoplasma isolation was a history of gynecological diseases, while a bachelor’s degree, master’s degree, or above were protective factors against Mycoplasma isolation. There were distinctly gradual increases in the positivity rates of U. urealyticum and M. hominis from 2015 to 2018 and an overall increasing trend of resistance to ten antibiotics among U. urealyticum and M. hominis. The top three antibiotics associated with resistance were ofloxacin, sparfloxacin, and levofloxacin. Doxycycline, josamycin, and minocycline were preferred because they had the lowest levels of resistance. Increases in the prevalence of infection and antibiotic resistance in U. urealyticum and M. hominis were observed from 2015 to 2018, clearly confirming the necessity to monitor the standardized administration of antibiotics.

Aim: To investigate the prevalence of common aerobic gram positive and gram negative bacteria, Mycoplasma hominis, Ureaplasma urealyticum and Chlamydia trachomatis in symptomatic and asymptomatic Greek patients and to determine antibiotic resistance profiles. Methods: This retrospective study included a total of 316 adult men examined at the Assisted Reproduction Department of IASO- Obstetrics and Gynecology clinic in Athens, Greece. Sperm have been collected and proceed to culture and antibiotic sensitivity at the Central Laboratories following a standard protocol. Results: Twelve inappropriate out of 316 samples were excluded from the study. Out of the remaining 304 sperm samples 111 (37.5 %) were positive. Antibiotic sensitivity testing detected resistances to some commonly used antibiotics such as b-lactams and the quinolones. Ureaplasma urealyticum and Mycoplasma hominis were the most frequently isolated bacteria (45%), followed by Enterobacteriaceae (40%) and Enterococci 12.6%. The majority of 45 Enterobacteriaceae isolates, were Escherichia coli (31 strains/68%) corresponding to 27.9% of the total number of positive cultures. One infection to Chlamydia trachomatis was detected by an immunochromatic rapid test, one Candida sp, one Pseudomonas aeruginosa, two M. hominis and three Streptococcus group B. Escherichia coli were resistant to b lactams in about 38.7% due to b-lactamase, and 22.5%, 9.6%, 6.4%, were resistant to nitrofurantoin, sulfamethoxazole and ciprofloxacin respectively. Enterococci have shown resistance due to b-lactamase and PBP 5 alteration/hyperproduction. Ureaplasmas were resistant to the fluoroquinolones tested ciprofloxacin and ofloxacin, at 72.2% and 62.3% respectively. Conclusion: Carriage of bacteria in sperm is controversial for its contribution in sperm quality and fertility. In our IVF unit, we follow a protocol of isolation and antibiotic profiling of bacteria from sperm culture regardless of their concentration in sperm and giving the numbers/ml. This helps doctors to distinguish carriage or infection and to decide about potential therapy. Given the antibiotic resistances shown by this study, the importance of culture against empiric therapy in assisted reproduction patients is also clearly demonstrated.

Introduction. Nongonococcal urethritis is the most common sexually transmitted infection in men, with vast majority of the etiological agents such as Chlamydia trachomatis, followed by urogenital mycoplasmas. The aim of this study was to determine the prevalence of Chlamydia trachomatis, Ureaplasma urealyticum and Mycoplasma hominis in nongonococcal urethritis in men, and to examine infections associated with these agents. Material and methods. 299 sexually active, heterosexual men with nongonococcal urethritis were included into the study. Urethral samples were taken with a dacron swab placed into the urethra up to 2-3 cm. The Direct immunojluorescence tehnique was performed for identification of Chlamydia trachomatis. Ureaplasma urealyticum and Mycoplasma hominis were detected with Mycoplasma 1ST assay. Results. Chlamydia trachomatis was detected in 22.75%, Uraeplasma urealyticum in 21.08% and Mycoplasma hominis in 8.02% cases. We found no significant differences in prevalence between Chlamydia trachomatis and Ureaplasma urealyticym (p>0.05). Monoinjections were found in 51.85% with significantly higher rate (p<0.01) than associated infections (11.70%). Among associated infections, coinfection of Chlamydia trahomatis and Ureaplasma urealyticum was predominant. Association of Chlamydia trachomatis with urogenital mycoplasmas was significantly higher (p<0.05) than the one between Ureaplasma urealyticum and Mycoplasma hominis. In 36.45% patients no patogenic microorganisms were detected. Conclusion. These results confirmed the etiological role of Chlamydia trachomatis and urogenital mycoplasmas in nongonococcal urethritis with prevalence of 51.85% in monoinfections and 11.70% in associated infections. In 36.45% of cases the etiology of urethritis was not elucidated. These results suggest that more sensitive diagnostic tool should be applied when searching for the detailed etiology of nongonococcal urethritis.

A 10-year-old girl with a 1-year history of lower genitourinary tract symptoms suggestive of bacterial infection but with numerous negative urine cultures was referred to the University of Alabama urology clinic after empirical treatment with multiple antibiotics failed to resolve her symptoms. An extensive urologic evaluation revealed no structural or physiologic abnormalities, but an exudative vaginitis was noted and large numbers of Ureaplasma urealyticum and Mycoplasma hominis were isolated from the lower genital tract. Cultures for Chlamydia, viruses, and routine bacterial pathogens were negative. After initiation of tetracycline therapy, symptoms resolved and subsequent cultures for mycoplasmas were negative. In addition, a seroconversion was noted for M hominis but not for U urealyticum. Chlamydia serology was negative. It was later learned that the patient had been sexually molested just prior to the onset of symptoms. This case illustrates the necessity of early consideration of a mycoplasmal etiology in the patient with persistent genitourinary symptoms and no obvious bacterial pathogen, or in the patient whose condition is refractory to routine antibiotic therapy.
