An epidemiological survey of Mycoplasma hominis and Ureaplasma urealyticum in gynaecological outpatients, Rome, Italy

Abstract

The objective of this study was to assess the prevalence of Ureaplasma urealyticum and Mycoplasma hominis infections and to investigate associations between their presence in the lower female genital tract and lifestyle characteristics. The study was performed on a population of 3115 women, comparing the demographic and behavioural characteristics of 872 women with U. urealyticum infection and 142 women with M. hominis with uninfected women, using univariate and multiple logistic regression analysis. The prevalence of infection with U. urealyticum was 28% and M. hominis was 4.6%. In multivariate logistic regression analysis, intrauterine device, number of sexual partners and age (<35 years) were significantly associated with U. urealyticum while previous induced abortion, condom use and young age at first intercourse (<16 years) were associated with M. hominis infection. U. urealyticum infection presents the same demographic and behavioural characteristics of a sexually transmitted disease. The unprotective role of condom use suggests a non-sexual mode of transmission of M. hominis infection.

Epidemiological investigation and antimicrobial susceptibility analysis of ureaplasma species andMycoplasmahominis in outpatients with genital manifestations

“…M hominis monoinfection was rare. These findings were consistent with the results reported in China recently,11 12 but the positive rates were higher than those reported in Italy13 and Hunngary 14. This discrepancy might be due to the variations in socioeconomic conditions and living standards.…”

Prevalence of Mycoplasma hominis and Ureaplasma spp. in Routine Gynecological Care in Sao Paulo City, Brazil

“…and age; suggesting that the presence of these microorganisms may not be associated with increased age. This finding matches with those of the previous studies conducted in a cohort of females with bacterial vaginosis (BV) or asymptomatics (6,22,25), in which Ureaplasma spp. was detected significantly more often than M. hominis.…”

Epidemiologic Factors and Urogenital Infections Associated With Preterm Birth in a Midwestern U.S. Population

“…These mollicute rates have been associated with sexual behaviors (20,21). Additionally, the carriage rate of M hominis or either Ureaplasma species was widespread in women who gave birth at < 35 weeks (Figure 1).…”

“…Conflicting associations between mollicutes and preterm birth have had a long history, not only related to population tested, but also to testing itself (culture vs PCR) (5,7,8,9,10,11,12,16,20,21,22,23,24,25,26). We used PCR probes that can separate M hominis , M genitalium , and U parvum from U urealyticum (18).…”
