Abstract: Objective To study the susceptibility of Mycoplasma hominis(Mh) to several antimicrobials and Chinese medicinal herbs. Methods The minimal inhibitory concentrations(MIC) of Mh to 11 antimicrobials and 19 herbs were detected by the method of liquid microdilution. Results The sensitivity of Mh to those antimicrobials from high to low, was as follows:lincomycin, tetracycline, minocycline, levofloxacin, ciprofloxacin, ofloxacin, rifampin, spiramycin, azithromycin, erythromycin ethyl succinate and erythromycin. Among 19 herbs,Mh was sensitive to Radix Isatidis, Radix Angelicae Dahuricae, Cortex Phellodendri, Rheam Officinale, Fructus Kochiae and Herba Houttuyniae. Conclusions The susceptibility of local isolates of Mh to common antimicrobials is found out. Six Mh sensitive Chinese medicinal herbs are screened. The study provides evidences of treating Mh infection by combination of antimicrobials with Chinese medicinal herbs.
