Recent clinical relevance of mono-genital colonization/infection by Ureaplasma parvum.

ABSTRACT

Ureaplasma parvum is the most prevalent genital mycoplasma in women of childbearing age. There is debate around the relevance of its presence in male or female genitals for disease development and as a cofactor. The objective of this study was to determine the prevalence of colonization/infection by U. parvum and its possible relationship with reproductive tract infections. We retrospectively analyzed the presence of U. parvum in patients referred by specialist clinicians for suspicion of genitourinary tract infection. U. parvum was detected in 23.8% of samples, significantly more frequently in females (39.9%) than in males (6%). Among the males, U. parvum was found alone in 68.4% of episodes, with Ct < 30. Among the females, U. parvum was detected in 88.6% of cases, with Ct < 30, including 22 cases with premature rupture of membranes and 6 cases with threat of preterm labor. Co-infection was significantly more frequent in females (62.6%) than in males (31.6%). Given the high prevalence of U. parvum as sole isolate in males and females with genitourinary symptoms, it should be considered in the diagnosis and treatment of genital infections, although its pathogenic role in some diseases has not been fully elucidated.
