Prevalence and Antimicrobial Susceptibility of Mycoplasma hominis and Ureaplasma Species in Nonpregnant Female Patients in South Korea Indicate an Increasing Trend of Pristinamycin-Resistant Isolates.

ABSTRACT: Mycoplasma hominis and Ureaplasma species, commonly found in the lower urogenital tract, have been associated with various urogenital infections. This study aimed to estimate the prevalence and antimicrobial susceptibility trend of M. hominis and Ureaplasma sp. in female patients and to evaluate the risk factors for the acquisition of pristinamycin-resistant mycoplasma. Endocervical swab specimens obtained between March 2016 and December 2018 were analyzed using a Mycoplasma IST2 kit. Because pristinamycin and josamycin are not available in South Korea, we conducted an age- and date-matched case-control study to evaluate the risk factors for the acquisition of pristinamycin-resistant isolates. Among 4,035 specimens, 1,589 (39.4%) cases were positive for genital mycoplasma, which included 49 (3.1%) cases of M. hominis, 1,243 (78.2%) cases of Ureaplasma sp., and 297 (18.7%) cases of both M. hominis and Ureaplasma species. Based on antimicrobial susceptibility tests, the antibiotic susceptible rate of both M. hominis and Ureaplasma species to pristinamycin decreased annually during the study period (100%, 97.1%, and 87.3% for 2016, 2017, and 2018, respectively, P?
