  • Description: Background Ureaplasma spp. are known to reside in the urogenital tract in adults and newborn children. In most cases, Ureaplasma spp. colonization is not harmful to the host. However, Ureaplasma spp. are also known to be involved in non-gonococcal urethritis (NGU) in adults and may also be connected to infertility. In pregnant women, there is speculation that Ureaplasma spp. may cause complications in pregnancy and lead to preterm labor. In preterm newborns Ureaplasma spp. colonization is associated with bronchopulmonary dysplasia. As azithromycin is first choice treatment either in adult as well as in newborn infections resistance to macrolides affects successful therapy. However, little is known about the susceptibility of Ureaplasma spp. In this study we assessed the prevalence of genital Ureaplasma spp. colonization and the prevalence of resistance associated mutations to macrolides.MethodsGenital samples of 512 women visiting our Dutch STI clinic who were routinely screened for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) were retrospectively tested with Ureaplasma spp. PCR (Amplisens). Of these patients 13% (66/512) were positive for CT and 1% (5/512) for NG. Forty five Ureaplasma positive samples were selected to determine mutations that could confer macrolide resistance by sequencing domain V of the 23S RNA gene.ResultsIn total 78%(401/512) samples were positive for Ureaplasma spp. Prevalence of Ureaplasma spp. was significantly higher (p<0.05) among the CT positive samples 88%(58/66) and the NG positive samples 80%(4/5). None of the 45 samples contained mutations associated with macrolide resistance.ConclusionWe found a higher prevalence of Ureaplasma spp. in a female patient cohort visiting an STI clinic compared to other studies. However, no resistance associated mutations to macrolides were detected. Higher prevalence of Ureaplasma spp. in STI positive samples underscores its sexually transmitting potential.DisclosureNo significant relationships.
