Background and Objectives: Sexually transmitted infections (STIs) can remain undetected and untreated; therefore, rapid diagnosis and treatment of STIs are important. Mycoplasma genitalium (MG), Mycoplasma hominis (MH), and Ureaplasma urealyticum are sexually transmitted pathogens that cause asymptomatic, organ-specific, and chronic infections, thereby pos- ing a threat to community health. Therefore, we investigated the epidemiological trends of MG and MH infections in South Korea for rapid diagnosis and treatment. Materials and Methods: From September 2018 to December 2020, samples (catheter, pus, tissue, swab, and urine) were collected from outpatients of hospitals in South Korea for molecular biological venereal disease testing. DNA was extracted and analyzed using real-time polymerase chain reaction. Results: Of the 59,381 samples analyzed, 8.78% (n=5,215) were positive for MG and MH. The MH positivity rate (5.51%, n=3,273) was higher than the MG positivity rate (3.27%, n=1,942). MG and MH positivity rates were the highest in patients aged <19 years. Men had higher MG positivity rate, whereas women had higher MH positivity rates. Furthermore, the MG- positivity rate was the highest in the swab samples of both men and women, whereas that of MH was the highest in the urine samples of men and swab samples of women. Conclusion: We identified the differences between MG and MH positivity rates based on sex, specimen, and age. Our findings can provide information for strategies that protect public health and reduce STI incidence and transmission.

Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Ureaplasma parvum, Ureaplasma urealyticum, Mycoplasma hominis and Mycoplasma genitalium are established or presumed as (??) STI pathogens. The present study aims  at ng describing the one-year molecular epidemiology of these seven pathogens in the Province of Bolzano, Northern Italy. From April 2016 to March 2017, a total of  2,949 patients, mainly females, were enrolled and 3,427 urine, vaginal, endocervical and/or urethral samples were subjected to simultaneous analysis of the seven pathogens by means of Real Time Polymerase Chain Reaction (AnyplexTM II STI-7 Detection Kit Seegene, Seoul, Korea). At least one of the seven microorganisms was detected in 40.7% of patients, with an uneven distribution: 43.1% in females (F) and 29.8% (p<0.001) in males (M). The prevalence of microorganisms was as follows: 30.3% U. parvum (F: 35.6%, M: 8.3%), 6.9% U. urealyticum (F: 6.8%, M: 7.0%), 4.9% M. hominis (F: 5.4%, M: 2.3%), 4.9% C. trachomatis (F: 3.4%, M: 11.4%), 1.1% M. genitalium (F: 1.0%, M: 1.2%), 1.2% N. gonorrhoeae (F: 0.17%, M: 5.6%) and 0.40% T. vaginalis (F: 0.38%, M: 0.53%). Mixed infections were detected in 7.4% of patients. The highest prevalence was observed for U. parvum, followed by U. urealyticum and M. hominis and a significant  presence of multi-pathogen infections was registered.

Introduction.The structure of incidence of sexually transmitted infections is changing constantly. Information on such changes supports correct planning of clinical and diagnostic activities of institutions providing specialized medical care by qualified specialists.Objective:to investigate the prevalence of sexually transmitted infections with pathogens clinically significant to the genitourinary system in Ukraine and at the local level.Materials and methods. Polymerase chain reaction was used to test the biological material obtained from the genitourinary clinical specimens from subjects with sexually transmitted infections, who underwent clinical and laboratory examinations in Oleksandrivsk Clinical Hospital (Kyiv, Ukraine) for Chlamydia trachomatis, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, Trichomonas vaginalis, Human papillomavirus, and Neisseria gonorrhoea. During 2017, 607 subjects of both genders, including 295 (48.6%) females and 312 (51.4%) males, were examined. Their mean age was 32±3.5.Findings. Chlamydia trachomatis was found in 159 (26.2%) of 607 examined subjects – 85 males and 74 females. Mycoplasma hominis was found in 122 of 585 (21.1%) examined subjects – 64 males and 58 females. Mycoplasma genitalium, respectively, in 17 (6.62%) of 258 subjects – 6 males and 11 females. Ureaplasma urealyticum was found in the largest number of subjects (305, i.e. in 48.77% of 601 examined subjects) – 157 males and 148 females. Trichomonas vaginalis was found in 28 (5.23%) of 535 subjects – 15 males and 13 females. Human papillomavirus was found in 158 of 297 (53.2%) examined subjects – 88 males and 70 females. Neisseria gonorrhea was found in 33 of 297 (8.45%) subjects – 8 males and 25 females.Conclusions. As suggested by the local study of the sexually transmitted infections incidence in Ukraine, the most clinically significant for the genitourinary system are Human papillomavirus (53.2%), Ureaplasma urealyticum (48.77%), Chlamydia trachomatis (26.2%) and Mycoplasma hominis (21.1%). Therefore, tests for these pathogens in the specified region is currently the most appropriate during diagnostic examinations and counselling of subjects with genitourinary infections.

Objective: Sexually transmitted infections are frequently seen and significant infections for public health. Prevention, early diagnosis and treatment of sexually transmitted infections have an important role in controlling the transmission of Human Immunodeficiency Virus (HIV). The investigation of the frequency of other sexually transmitted pathogens in asymptomatic HIV- positive individuals was aimed in the present study. Method: Vaginal and urethral swab samples were collected by 90 HIV- positive asymptomatic individuals themselves aged between 20-69 (median=36, SD=10.48) years, between September 2015 and April 2016. The samples were assessed for the presence of Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma urealyticum, Ureaplasma parvum, Herpes simplex virus type 1 and 2, and Human papillomavirus using real-time polymerase chain reaction (PCR) method. Results: At least one or more than one sexually transmitted pathogen was identified in 49 (54.4%) of 90 HIV-positive individuals. Human Papillomavirus was found in 31 (34.4%), Ureaplasma urealyticum in 20 (22.2%), Ureaplasma parvum in 15 (16.6%), Mycoplasma genitalium in 8 (8.8%), Mycoplasma hominis in 8 (8.8%), Neisseria gonorrhoeae in 5 (5.5%) and Chlamydia trachomatis in 2 (2.2%) individuals. Trichomonas vaginalis, Herpes simplex virus type 1 and 2 were not detected in any of the clinical specimens. Conclusion: Approximately 55% of 90 HIV- positive individuals were found to be positive for sexually transmitted pathogens, and . Human Papillomavirus was the most frequently detected pathogen. This condition reveals the necessity of screening even asymptomatic individuals for the presence of this pathogen. Studies are needed to increase awareness in our country on this issue.

 INTRODUCTION: Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV) and Mycoplasma genitalium (MG) infections are well recognized and prevalent sexually transmitted infections (STIs). The role of Mycoplasma spp and Ureaplasma spp are still controversial as some are commensals of genitourinary tract. OBJECTIVES: To estimate the prevalence rate of 7 organisms: Chlamydia trachomatis, Neisseria gonorrhoea, Mycoplasma genitalium, Trichomonas vaginalis, Mycoplasma hominis, Ureaplasma urealyticum (UU) and Ureaplasma parvum (UP) in infertile married couples during infertility evaluation. MATERIALS & METHODS: A total of 274 samples from all of the 137 couples who attended the reproductive center from June to December 2014 were collected. Detection of the organisms was performed using multiplex polymerase chain reaction. RESULTS: STI-associated organisms were detected in 35.4% (97/274) of subjects. The prevalence rates of CT, MG, TV, UU, MH were 7.3%,1.1%, 0.4%,5.4% and 5.1% respectively. Twenty-one (7.7%) subjects were positive for more than one organism. 24/274 (8.8%) of subjects had history of urogenital tract-related symptoms and 50% (12/24) were tested positive to one or more organisms. The presence of symptoms in both male and female subjects were found to be 10% (2/20) in CT infection, 10% (7/67) in UP, 14% (2/14) in MH and 13% (2/15) in UU infections. CONCLUSION: Sexually transmitted organisms were detected in one third of subjects planning for fertility evaluation. The absence of symptom in most subjects particularly in CT infection emphasizes the need for microbiological screening during infertility evaluation. The presence of genital ureaplasmas and mycoplasmas in infertile couples should not be neglected. There is a growing need to clarify whether their roles are simply colonizers or pathogens implicated in infertility.

Abstract Sexually transmitted diseases (STDs) are a very important cause of illness worldwide and prolonged, untreated infections with STD pathogens may have serious consequences. Our study aims to evaluate the distribution of six different STDs (Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, Ureaplasma urealyticum, Mycoplasma hominis and Mycoplasma genitalium) in male urine samples. First void urine samples from 52 symptomatic patients were collected between April 2014 and April 2015. DNA was extracted, purified and amplified via multiplex polymerase chain reaction (PCR) for the detection of the six STD pathogens, further identified using a 2% agarose gel electrophoresis with ethidium bromide as staining agent. STD frequency in the study group was 53.84 % (28 patients), mostly in the 20-29 years age group. Among positive patients, six presented multiple infections. 35 positive DNA samples were identified in the study: 17 of C. trachomatis, 9 of U. urealyticum, 7 of N. gonorrhoeae and 2 of M. genitalium. Wide scale application of the system based on the simultaneous detection of these six pathogens inducing STD may facilitate diagnosis, especially in multiple infections.

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.

SUMMARYUreaplasma urealyticum organisms (ureaplasmas) and Mycoplasma hominis organisms (mycoplasmas) were sought in mid-stream urines collected from 200 men and 200 women attending hospital with conditions of a non-venereal nature. In addition, the urines from 100 male and 100 female healthy volunteers were examined. Overall, ureaplasmas were isolated four times more often than mycoplasmas. In individuals less than 50 years of age, the organisms were found in about 20 % of men and about 40 % of women. In individuals 50 years or older, they were found about one-third to one-half as frequently. Centrifugation of urine and examination of the resuspended deposit did not increase the isolation rates. In men, the numbers of organisms in the urine were usually small (< 103 c.c.u./ml) with less than tenfold more in the urine of women. The occurrence of 51– > 1000 leucocytes per mm3 in some of the urines was not associated with either the presence or an increased number of ureaplasmas/mycoplasmas, whereas they were associated with the presence of 105 or more bacteria/ml. The significance of these findings in the context of defining the role of ureaplasmas/mycoplasmas in genital-tract disease is discussed.

Tanzania faces one of the highest cervical cancer burdens in the world. Recent work has suggested that the bacterial family Mycoplasmataceae is associated with higher levels of human papillomavirus (HPV), human immunodeficiency virus (HIV), and pre-cancerous cervical lesions. Mycoplasmataceae infection in Tanzania is not well understood, especially when considering the differences between sexually transmitted species of Mycoplasmataceae. To establish the prevalence of common Mycoplasmataceae cervical infections and evaluate their relationship with risk factors for cervical cancer, 1160 Tanzanian women responded to an epidemiological questionnaire and were tested for HIV, HPV, cervical lesions, Mycoplasma genitalium, Mycoplasma hominis, Ureaplasma spp., and Lactobacillus iners. A subset of 134 women were used for 16s metagenomic sequencing of cervical DNA to establish the relative abundance of Mycoplasmataceae and Lactobacillus present. PCR detection of bacteria at the cervix found Ureaplasma spp. in 51.4% of women, M. hominis in 34%, M. genitalium in 2.3%, and L. iners in 75.6%. M. hominis and M. genitalium infection were significantly more prevalent among women with HPV and HIV. M. hominis prevalence was similar despite severity of cervical lesions; however, abundance of M. hominis increased significantly in women with cervical lesions. These results emphasize the importance of understanding the relationship between M. hominis and HPV-related cervical pathogenesis.

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.
