of choice for the treatment of S. iniae infection in mammals, including humans. In the 1995–1996 cluster of human cases, all clinical isolates were susceptible to penicillin, several cephalosporins, clindamycin, erythromycin, and co-trimoxazole (MICs 0.25 μg/ml); all nine patients were treated with parenteral beta-lactam antibiotics and recovered uneventfully. A study of isolates submitted to the Centers for Disease Control and Prevention between 2000 and 2004 found all to be sensitive to beta-lactams, macrolides, quinolones, and vancomycin.
