Antimicrobial-resistant pathogens in animals and man: prescribing, practices and policies.
This meeting focused on infections in humans and animals due to methicillin-resistant Staphylococcus aureus (MRSA), extended-spectrum beta-lactamase (ESBL)-producing bacteria and Clostridium difficile, and their corresponding treatments. MRSA is predominantly a human pathogen, and molecular typing has revealed that certain clones have spread widely both between humans and from humans to animals. ESBL-producing bacteria, particularly those that express the CTX-M beta-lactamases, have been disseminated worldwide. ⋯ There is a concern that the numbers of MRSA or other antimicrobial-resistant bacteria might increase further when human isolates become established in animals, as this can amplify the numbers of such bacteria by dissemination within animal groups with subsequent spread back to humans. Certain antimicrobials have been implicated in the selection of MRSA, ESBL-producing bacteria and predisposition to infection by C. difficile. Guidelines for treatment and prevention of infections by MRSA, ESBL-producing bacteria and C. difficile were discussed and evidence-based policies were recommended for both humans and animals.
