Occurrence of Mycoplasma spp. and Ureaplasma spp. in genital specimens

Mycoplasma spp. and Ureaplasma spp. belong to humans’ genitourinary microbiota and sometimes are associated with infections of the genitourinary tract. The aim of this study was to evaluate the occurrence of Mycoplasma spp. and Ureaplasma spp. in genital specimens from patients of the 15 Regional de Saúde of Paraná State, Brazil, and to correlate the results with clinical and laboratory data. A retrospective cross-sectional study was conducted, based on the analysis of results of vaginal, endocervical, urine and urethral culture for mycoplasmas from patients attended in a reference laboratory, from January 2009 to December 2016. We evaluated 2,475 results of culture for mycoplasmas. A total of 50.8% patients were positive for mycoplasmas. Of these, 76.8% had positive culture exclusively for Ureaplasma spp. and 4.7% for Mycoplasma hominis. Both microorganisms were isolated in the microbiology culture of 18.5% of patients. Among the positive culture, 81.4% had significant concentrations. Bacterial vaginosis was the most common alteration observed in association with mycoplasmas. The high positivity of cultures for mycoplasmas, especially Ureaplasma spp. found in our study, highlight the presence of these microorganisms in many of the genital tract disorders that can be sexually transmitted and, consequently, should not be neglected.
