Antimicrobial resistance: a veterinary perspective

Abstract

Bacterial disease is a major constraint on the efficient production of animal derived food and causes ill health and suffering in both food producing and companion animals. In some production systems the spread of bacterial disease may be accelerated by the proximity of the animals. Bacterial disease may be controlled in some situations by eradication, maintenance of animals of specified health status, vaccination, and good hygiene. Nevertheless, antimicrobial chemotherapy remains vitally important for treating and in some cases preventing bacterial disease. Many bacterial diseases of animals are potentially fatal; others cause pain and distress. Appropriate use of antimicrobials will cure some sick animals and speed the recovery of others, and may improve the welfare of treated animals and reduce the spread of infection to other animals or, in the case of zoonotic disease, to humans. The challenge is to use antimicrobials wisely, minimising the risk of resistance
