INTERPRETIVE CRITERIA FOR ANTIMICROBIAL SUSCEPTIBILITY TESTING OF CEFTIOFUR AGAINST BACTERIA ASSOCIATED WITH BOVINE MASTITIS

摘要

The NCCLS Veterinary Antimicrobial Susceptibility Testing Subcommittee (V-AST) approved interpretive criteria for susceptibility testing of bovine mastitis pathogens with ceftiofur in June 2003 Table 1 (NCCLS). V-AST previously approved interpretive criteria for bovine and swine respiratory disease pathogens however, minimum inhibitory concentration (MIC) breakpoint and disk diffusion interpretive criteria had not been established for bovine mastitis pathogens. Ceftiofur has been approved for use asan intramuscular, injectable therapeutic for the treatment of bovine respiratory disease since 1988, and is currently being developed for the intramammary treatment of bovine mastitis.
