Prevalence and Antimicrobial Susceptibility of Ureaplasma urealyticum and Mycoplasma hominis in Female Outpatients, 2017 - 2021.

BACKGROUND

The latest region-specific panel of mycoplasma species is often crucial for providing insights into local mycoplasma epidemiology and updating clinical practice guidance.

METHODS

We retrospectively reviewed reports of 4,166 female outpatients detected by the mycoplasma identification verification and antibiotic susceptibility kit from the last five years.

RESULTS

Among them, > 73.3% of cases with Ureaplasma urealyticum or Mycoplasma hominis single infection or co-infection with both species were susceptible to three tetracyclines and one macrolide (josamycin). Additionally, > 84.8%, ≤ 4.4%, and ≤ 39.6% of the U. urealyticum, M. hominis, and co-infection cases, respectively, were susceptible to clarithromycin and roxithromycin. Four quinolones (ciprofloxacin, ofloxacin, sparfloxacin, and levofloxacin) and three macrolides (azithromycin, erythromycin, and acetylspiramycin) were active against < 48.9% of the isolates. Furthermore, 77.8%, 18.4%, and 7.5% of the M. hominis, U. urealyticum, and co-infection cases, respectively, were susceptible to spectinomycin.

CONCLUSIONS

Tetracyclines and josamycin were the best antibiotics for most mycoplasma-infected patients.
