  1. aThe genetic diversity was assessed by MLVA typing [32]. A cutoff value of 85% similarity was applied to define MLVA types. bThe capsular type was identified by multiplex-PCR [43]. cErythromycin resistance phenotype was determined by the double-disk diffusion method [46]. dThe presence of specified gene was determined by PCR. (+) Presence; (-) Absence. eThe minimum inhibitory concentrations (MIC) were determined by the agar-dilution method. Clindamycin (DA); Erythromycin (E).
