Antimicrobial susceptibility of florfenicol (FFC) against 243 bacterial agents isolated in Korea from cattle and pigs with respiratory disease were investigated by agar diffusion and microdilution broth methods following the recommendations provided by the National Committee for Clinical Laboratory standards. All Actinobacillus pleuropnemoniae, Pasteurella multiocida, Mannheimia haemolytica and 98.6% of the Bordetella bronchiseptica isolates were susceptible to FFC, which as significantly more effective than the other antibiotics used in this study. FFC also showed high in vitro antimicrobial activities (MIC90 <= 1 mu g/ml) against all strains tested with a minimal inhibitory concentration (MIC) determination ranging from 0.12 to 4 mu g/l. No resistant strains of A. pleuropneumoniae, P. multocida and M. haemolytica to FFC have apparently developed since the first introduction of this antibiotics for veterinary use in Korea. The results suggest that FFC is therapeutically valuable in the treatment of primary or complicating bacterial pathogens causing of the bovine and swine respiratory tract. (c) 2004 B.V.
