Females abortion is one of the most important sequela of genital infection with Chlamydia trachomatis, Mycoplasma hominis and Ureaplasma urealyticum. In this study frequency of Chlamydia trachomatis, Mycoplasma hominis and Ureaplasma urealyticum was studied in 125 females with habitual abortion by direct and indirect immunofluorescence tests and culture method and compared with 250 normal population. The results obtained were as follow: Mycoplasma hominis was isolated from 18 (14.4%) females with habitual abortion and 18 (7.2%) normal population (P=0.0139). Ureaplasma urealyticum was isolated from 39 (31.2%) females with habitual abortion and 48 (19.2%) normal population (P= 0.0045). Chlamydia trachomatis was detected by direct immunofluorescence test in 9 (7.2%) of cases and 2 (0.8%) of control groups (P=0.0002). The antibody titer against D-K serotypes of Chlamydia trachomatis was also measured. The valuable titer of antibody (>1/16) was detected in 15 (12%) of cases and 8 (3.2%) of control groups (P=0.0004). The results show that Chlamydia trachomatis and Ureaplasma urealyticum may be responsible for some cases of abortion.

Background and objectives: Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) are two commensal microorganisms that form the urogenital microbiota. Under a state of dysbiosis, both bacteria cause intrauterine infection. Material and methods: Therefore, the purpose of the present study was to analyze the prevalence of UU and MH among four hundred and eleven infertile women. Results: Women between thirty and thirty-five years old were the most affected group, followed by those that were 25 and 30 years old, respectively. Cumulatively, the prevalence of single UU and MH, and coinfection, was 28.46% (n = 117), (n = 2) 0.48%, and 2.91% (n = 12), respectively, with an overall detection rate of 31.87% (n = 131). To assess the associated drug susceptibility, endocervical samples were unequally sent to Regina Maria (n = 281) and Synevo (n = 130) laboratories for further analyses. Pristinamycin (100% vs. 100%) and Josamycin (100% vs. 98.00%) were the most efficient antibiotics in eradica...

Background: Genetic evidence of asymptomatic Mycoplasma hominis (M. hominis) and Ureaplasma urealyticum (U. urealyticum) infection associated with infertility among females is lacking because suitable high throughput molecular methods have not been applied. Objective: This study aimed to explore the occurrence of M. hominis and U. urealyticum in the genital tract of females with asymptomatic infection and infertility as well as determine their genetic relatedness. Materials and Methods: The study group included 100 asymptomatic females and 31 females diagnosed with infertility. Sequencing of the 16S rRNA gene following DNA extraction was performed directly from endo-cervical swabs. Phylogenetic analysis established the genetic linkage between the isolates from both groups. Results: In asymptomatic females, M. hominis and U. urealyticum were detected with a prevalence of 8% and 2% respectively. Among females with infertility, the prevalence was 6.45% and 3.23% for M. hominis and U. u...

Among the organisms that cause genital infection are Mycoplasma hominis and Ureaplasma urealyticum which are commensally in women urogenital but may become pathogens and were associated as a cause of complications of genital tract infection in pregnant women, such as ascending chorioamnionitis, premature rupture of membranes, preterm birth, miscarriage, weight and neonatal birth low and newborn deaths..The objective of this study was to describe the characteristic of multiparous women with Mycoplasma hominis and Ureaplasma urealyticum infection. Design of the study was a descriptive study with cross-sectional approach by collecting cervical swab of 50 multiparous women from outpatient clinic in Medan. Duplex PCR assay was perfomed using two primers: RNAH1 and RNAH2 that amplify the 16sRNA M. Hominis gene at 334bp; UMS125 and UMA226 amplifying serovar3 genes multiple banded antigen which can amplify biovar1 that appeared at 403bp and biovar2 appeared at 448bp. The result of this stud...

The purpose of this study was to determine the isolation rates of Mycoplasma hominis and Ureaplasma urealyticum from three populations of women and also to relate the presence of these microorganisms with some indicators of nonspecific vaginitis. Three hundred vaginal swabs were taken from delivery, pregnant and control (not pregnant) women. Cultures were done in E broth supplemented with arginine or urea. M. hominis was isolated in 5% at delivery, 12% from pregnant and 5% from control women and U. urealyticum was isolated in 21%, 31% and 28% respectively. There was statistical difference in the isolation rate of M. hominis in pregnant women respect to the other groups. Both microorganisms were more frequently isolated in women with acid vaginal pH, amine-like odor in KOH test, clue cells and leucorrhea. M. hominis was isolated in 17% and U. urealyticum in 52% from women with nonspecific vaginitis. M. hominis was isolated in 2% and U. urealyticum in 13% from women without nonspecifi...
Prevalence of Mycoplasma hominis and Ureaplasma urealyticum in Genital Tract Infections
2009
Background: Mycoplasmas (Mycoplasma spp. and Ureaplasma spp.) are sexually transmitted organisms found primarily in the human urogenital microbiota. These microorganisms are frequently associated with some diseases including non-gonococcal urethritis, vaginosis, pregnancy complications, prenatal infections, systemic infections and infertility. Objectives: The current study aimed to evaluate the prevalence of Mycoplasma hominis and Ureaplasma spp. in routine gynecological care. Patients and Methods: A cross sectional study with simple random sampling was designed. A total of 6,810 patients with the age range of 11 to 80 years were evaluated, during a six-month period from January 2015 to June 2015 in Sao Paulo, Brazil. DNAs were extracted from cytological samples (ThinPrep™) to detect microorganisms by real-time polymerase chain reaction (qPCR). Results: The high prevalence of M. hominis (n = 79), Ureaplasma spp. (n = 2,026) and the co-colonization of both (n = 199) with P < 0.0001 in the samples were verified, mainly in sexually active aged females. The results also indicated a negative and significant correlation between co-colonization of Ureaplasma spp. and M. hominis, Ureaplasma spp., and age. Conclusions: In conclusion, the data showed that high rate of females harbor these microorganisms in the genital microbiota. This finding suggests the importance of routine gynecological tests, mainly in pregnant females, during the second and third trimesters, and in asymptomatic females under infertility clinical investigation. Furthermore, the application of molecular methods is suggested; since they provide a fast and accurate diagnosis of these microorganisms, but sensitivity of the tests should be considered in the clinical relevant concentration of microorganisms in the genital microbiota.

Purpose: The prevalence of Ureaplasma urealyticum and Mycoplasma hominis m the endocervix at the time of oocyte collection in women undergoing in vitro fertilization (IVF; was examined using the polymerase chain reaction (PCR). Methods: All women were treated with tetracycline following sample collection. Results: U. urealyticum was identified in 56 (17.2%) of 326 women while M. hominis was present in only 5 (2.1%) of 235 women. U. urealyticum was detected at a higher frequency (P = 0.01) in those women whose 1VF cycle failed prior to embryo transfer. This organism was present in 8 off9 (42.1%) women with either no fertilization or no embryo transfer, 19 of 148 (12.8%) who had no evidence of pregnancy following embryo transfer, 6 of 30 (20.0%) who had only a transient (biochemical) pregnancy, 5 oft4 (35.7%) with a spontaneous abortion, and 18 of 115 (15.6%) with a term bh'th. Of the eight women with U. urealyticum who had no embryos transferred, malefactor was the cause of infertility in five cases, two women had tubal occlusions while in one woman the diagnosis was idiopathic. Therefore, poor sperm quality, and not a U. urealyticum infection, might explain the failure of most of these cases to proceed to the stage of embryo transfer. Analysis of all patients revealed no as-4 To whom correspondence should be directed. sociation between male factor infertility and U. urealyticurn in the cervix. Conclusions: U. urealyticum, but not M. hominis, is present in the cervices of many culture-negative women. Its presence, however, does not influence IVF outcome subsequent to embryo transfer in women treated with tetracycline after oocyte retrieval.

Female and male infertility have been associated to Chlamydia trachomatis, Ureaplasma spp. and Mycoplasma hominis urogenital infections. However, evidence from large studies assessing their prevalence and putative associations in patients with infertility is still scarce. The study design was a cross-sectional study including 5464 patients with a recent diagnosis of couple’s primary infertility and 404 healthy control individuals from Cordoba, Argentina. Overall, the prevalence of C. trachomatis, Ureaplasma spp. and M. hominis urogenital infection was significantly higher in patients than in control individuals (5.3%, 22.8% and 7.4% vs. 2.0%, 17.8% and 1.7%, respectively). C. trachomatis and M. hominis infections were significantly more prevalent in male patients whereas Ureaplasma spp. and M. hominis infections were more prevalent in female patients. Of clinical importance, C. trachomatis and Ureaplasma spp. infections were significantly higher in patients younger than 25 years. Mo...

Background: Genital ureaplasmas (Ureaplasma urealyticum and Ureaplasma parvum) and mycoplasmas (Mycoplasma genitalium and Mycoplasma hominis) are potentially pathogenic species playing an etiologic role in both genital infections and male infertility. Reports are, however, controversial regarding the effects of these microorganisms infections in the sperm seminological variables. This study aimed at determining the frequency of genital ureplasmas and mycoplasmas in semen specimens collected from infertile men, and at comparing the seminological variables of semen from infected and non-infected men with these microorganisms.

Objective To determine the prevalence of U. urealyticum and M. hominis in semen samples collected from men admitted in clinic for infertility, and to compare the quality of these semen samples. Methods A total of 1 058 semen samples collected were investigated. Sperm semiological assays were performed according to the guidelines of the World Health Organisation (WHO). Semen were examined by Mycoplasma IST for the detection of mycoplasma. Semen culture on agar media was used to detect other microorganisms. Chlamydia was detected using direct fluorescent assay (DFA) of Clamydia Trachomatis. Results Among 1 058 semen samples, microorganisms were detected in 638 (60.3%). The infected sperms consisted of mycoplasma alone in 507 cases (47.9%), mycoplasma and other microorganisms in 98 (9.3%), giving in all 605 (57.2%) samples infected with mycoplasma. The last 33 (3.1%) consisted of other microorganisms alone. The frequency of U.urealyticum, M. hominis and mixed genital infections detected in semen samples of infertile men were 39%, 23.8% and 5.6%, respectively. The rates of abnormal semen parameters recorded among patients infected with mycoplasma were for volume (22.2%-25%), viscosity (29.6%-43.5%), pH (64.7%-72.9%), motility (80.8%-93.8%), morphology (36.3%-47.9%), sperm concentration (53.3%-58.3%) and leukocyte count (51.4%-58.3%). Conclusion Frequency of U. urealyticum infection was higher than that of M. hominis. Mycoplasma infections were associated with disorders of pH, motility and sperm concentration. In addition M. hominis infection affected spermatozoa morphology. Therefore, screening of U. urealyticum and M. hominis for routine semen analysis is clinically relevant in Abidjan.
