Prevalence and antimicrobial susceptibility of genital Mycoplasmas detected by Mycoplasma IST 2 from urogenital samples in Padua, Italy, between January 2014 and December 2015

Abstract

Background and aims. The aim of this study is to define the epidemiology and the antimicrobial resistance profile of Ureaplasma spp. and Mycoplasma hominis isolated from urogenital specimens of patients attending the Microbiology and Virology Unit of Padua between January 2014 and December 2015. Materials and methods. The analysis was carried out on a total of 10861 samples. Species identification and antimicrobial susceptibility tests were performed using bioMérieux Mycoplasma IST 2. Results. 2668 samples (24.6%) from 2043 patients were positive: 2466 samples positive for Ureaplasma spp. (1897 patients) and 8 samples positive for M. hominis (8 patients), while in 194 samples (138 patients) was detected a coinfection. As for antimicrobial susceptibility of Ureaplasma spp. we found a resistance (R+I) rate of 90.6% for ciprofloxacin, of 74,1% for ofloxacin, of 52.8% for azithromycin and of 47.0% for erythromycin.Conclusions. Our report shows a high prevalence of Ureaplasma spp. in the study population. Surveillance of antibiotic resistance is critical for an appropriate therapeutic approach, which must always be contextualized with patient’s symptomatology.
