CONTROL OF METHICILLIN-RESISTANT STAPHYLOCOCCUS AUREUS (MRSA) IN CLINICS THE COMMUNITY

摘要

Staphylococcus aureus is a Gram positive opportunistic pathogen that is part of the commensal micro flora in many species, including horses. As an opportunist, S. aureus can reside in or on a host without any apparent problems, however infections canoccur in certain situations. One problematic aspect of S. aureus is its tendency to develop or acquire resistance to antimicrobials. Penicillin-resistant S. aureus was identified shortly after widespread use of penicillin in humans; first in hospitals, then in the general population. This resistance was mediated through beta-lactamase production, so antimicrobials that were resistant to the effects of beta-lactamase (i.e. methicillin) were developed. However, methicillin-resistant S. aureus (MRSA) emerged in humans shortly thereafter.
