The frequency of their resistance to penicillin and ampicillin was 76.8 % ( 159/207 ) , followed by erythromycin ( 56 % , 116/207 ) , trimethoprim-sulfamethoxazole ( 28.5 % , 59/207 ) , chloramphenicol ( 24.2 % , 50/207 ) , kanamycin ( 19.8 % , 41/207 ) , and doxycycline ( 1.4 % , 3/207 ) .
Antimicrobial susceptibilities of exfoliative toxigenic and non-toxigenic Staphylococcus hyicus strains in Japan. Staphylococcus hyicus isolates (n=207), including 150 exfolitative toxigenic and 57 non-toxigenic strains, were examined for their susceptibility to 13 antimicrobial agents by using the dehydrated 96-well MIC panel system. The frequency of their resistance to penicillin and ampicillin was 76.8 % ( 159/207 ) , followed by erythromycin ( 56 % , 116/207 ) , trimethoprim-sulfamethoxazole ( 28.5 % , 59/207 ) , chloramphenicol ( 24.2 % , 50/207 ) , kanamycin ( 19.8 % , 41/207 ) , and doxycycline ( 1.4 % , 3/207 ) . Resistance to chloramphenicol and trimethoprim-sulfamethoxazole was significantly higher in toxigenic strains than non-toxigenic strains (p<0.01), whereas kanamycin and erythromycin resistance was significantly higher in non-toxigenic strains (p<0.01 and <0.05, respectively). Resistance to two or more antimicrobials was observed in 85.5% (177/207) of total strains, with a significantly higher occurrence in toxigenic strains (89.3%, 134/150 vs. 75.4%, 43/57; p<0.05).
