Abstract


Antmicrobial susceptibility test was performed in thirty-one samples of Rhodococcus equi isolated from iung infections in foals. Among the antimicrobial tosted, erythromycin (100,0 %), rifampin (96.3%). neomycin (93,6 %)Josamycin (90,4%) and gentamicin (90,4 %)presented the highest sensitivity against R- equi- The most-common occurrence of resistance was observed from cephalexim (100,0 %}, lincomycin (100,0 %), cephalothin (96,3 %). oxacillin (96,8 %), penicillin G (96,8 %), amoxicillin (90,3 %) and trimethoprim/sulfamethoxazole (83,8 %). The highest susceptibility of the R. equi to josamycin, suggest the drug as alternative for therapy of R. equi infections in foals.
