Epidemiological investigation and antimicrobial susceptibility analysis of mycoplasma in patients with genital manifestations.

Background: The aim of this study was to investigate the infection and antimicrobial resistance of Ureaplasma urealyticum and Mycoplasma hominis in patients with genitourinary symptoms among Hakka population in Meizhou, China.

Methods: A total of 12 633 females and 3315 males who presented urogenital symptoms and were subjected to mycoplasma tests from 2014 to 2018 were enrolled in this study. The mycoplasma detection and antimicrobial susceptibility were tested using the Mycoplasma ID/AST kit.

Results: The total incidence of mycoplasma infection, as well as the incidence of U urealyticum in Hakka population was annually increasing from 2014 to 2018. The total incidences and U urealyticum infection were more prevalent in females than males. Higher positive rate of mycoplasmas infection was observed in women aged 16-20 (50.9%) and men aged 26-30 (25.4%). The occurrence of antimicrobial resistance of mycoplasma to antibacterial agents remained relatively similar in the past five years. Ureaplasma urealyticum infection, M hominis infection, and co-infection of resistance to levofloxacin, erythromycin, ciprofloxacin, ofloxacin, roxithromycin, azithromycin, clarithromycin, and sparfloxacin were dramatically higher in females than in males.

Conclusion: Our findings indicate a high burden of mycoplasmas infection and antimicrobial resistance of mycoplasmas infection among females, and josamycin and minocycline may be recommended as the primary choice in clinical treatment of anti-mycoplasmas.
