Abstract

The minimun inhibitory concentration (MIC) was determined toward amoxicilin, ampicilin, penicillin, ceftiofur, florfenicol, lincomycin, trimethoprim-sulfadiazine and tetracycline for 75 strains of Streptococcus suis. The MIC was performed on sheep blood agar plates containing concentrations varying from 0,25 to 256 µg/ml of the antibiotic described above. The amoxicilin in the concentrations of 1 and 2 µg/ml, florfenicol in the concentration of 1 µg/ml and trimethoprim-sulfadiazine in the concentrations of 2 e 8 µg/ml, were the antibiotics that presented minor resistance. In contrast, the ampicilin, tetracycline, ceftiofur and lincomycin, presented MIC of 64 and 128 µg/ml, 64 and 128 µg/ml, 128 and 256 µg/ml and >;256 µg/ml, respectively. The results of this study show that the amoxicilin and florfenicol are the antibiotics of choice for the treatment of diseases by S. suis in swine.
