Methicillin-resistant Staphylococcus aureus in horses and horse personnel.
Fortunately, MRSA infection and colonization are currently uncommon in veterinary medicine. Nevertheless, the increasing reports of the occurrence of MRSA infection in horses, veterinarians, and equine personnel dictate that serious consideration be given to the control of this pathogen in veterinary hospitals as well as in the equine community. It is unclear whether extrapolation from human hospitals and people in the community is appropriate; however, given the rapid increase in nosocomial MRSA in human hospitals and the recent shift of certain clones of MRSA into the community, it would be unwise to ignore this potential pathogen. If equine MRSA did, indeed, originate in the human population, complete eradication in the equine population is unlikely, regardless of the prevalence of infection in horses and the intensity of infection control measures, without concurrent eradication of MRSA in the human population, which is surely an impossible feat. Early institution of appropriate surveillance and other infection control measures should be used to attempt to limit the impact of MRSA in veterinary medicine, however. It has been stated, "The time to act is now, before the prevalence of MRSA in the community begins to rise and we end up with 50% of the community strains becoming methicillin-resistant". This statement was directed at control of MRSA in people; however, it is equally relevant in the veterinary context and should receive strong consideration.
