Antimicrobial Susceptibility Testing in Veterinary Medicine
Antimicrobial susceptibility testing (AST) is a systematic in vitro laboratory method that determines which antimicrobial agents are effective against an isolated bacterial or fungal pathogen. Standardized by the Clinical and Laboratory Standards Institute (CLSI) and other regulatory bodies since the 1960s, AST guides targeted therapeutic decisions, supports infection control, and generates epidemiological data on resistance patterns essential for combating antimicrobial resistance in animal populations.
