Controversies exist regarding the use, misuse and potential overuse of antimicrobial treatments in foals and adults. When antimicrobials are required for treatment of infectious diseases, veterinarians should follow a logical approach and not simply reach for the newest drug. Targeted, single drug therapy is probably best, and culture and sensitivity testing should be undertaken. The most likely infectious agent, potential drug toxicities, and age-appropriate dose and route should be considered. The development of an increasing number of different multiple drug resistant pathogens requires that veterinarians use antimicrobial drugs responsibly to protect veterinary patients and the public at large.
