OBJECTIVE To evaluate the effect of erythromycin and levofloxacin alone or in combination against ureaplasma urealyticurru METHODS Multiple-proportional broth microdilution method for erythromycin and levofoxacin alone and checkerboard titration methods for them in combination were applied to detect the MICs against ureaplasma urealyticum. The resuhs were evaluated with both fractional inhibitory concentration index and Ridit analysis. The resistant concentratxon tor both erythromycin and levofloxacin was set MIC≥8 mg· L^- 1.
