Abstract

MRSA Zoonoses Horses Public Health
Recognized as a hospital-acquired, community-associated, and zoonotic pathogen, methicillin-resistant staphylococcus aureus (MRSA) is a problematic disease-producing agent that concerns both humans and animals. MRSA is a highly versatile organism with adaptable capabilities and horses, specifically, are particularly pre-disposed to MRSA colonization and infection. Colonized horses serve as MRSA reservoirs in the community and are capable of transmitting MRSA to humans. Currently, infection control measures for veterinarians are outlined in the Compendium of Veterinary Standard Precautions for Zoonotic Disease Prevention in Veterinary Personnel (Compendium). However, there is no known extensive document or protocol in place that offers preventative guidance for equine personnel outside of a clinic setting. The purpose of this project was to examine existing information regarding equine MRSA transmission, as well as to thoroughly investigate the Compendium and assess the practicality of using it as a template for the equine industry. Additional project aims included identifying the stakeholders and platform needed to begin the process of providing reasonable guidance for equine MRSA control. This project consisted of literature reviews specific to equine MRSA transmission, assessments of barrier precautions and infection control measures, and interviews with experts on equine MRSA and Compendium co-authors. Though not a perfect model, results indicate that the Compendium does have the capacity to be used as a template for the equine industry. Creation of infection control guidelines in the equine industry will be the result of a team effort by specialists, public health officials, and industry leaders actively working together. Guidelines will gain strength, support and recognition in the horse world, if overarching regulatory agencies already firmly in place in the industry such as the United States Equestrian Federation (USEF) and the United States Hunter Jumper Association (USHJA) participate in guideline development and dissemination. It is recommended that public health agencies approach the equine industry with a guidance perspective and partner with local horsemen and USEF/USHJA leaders in order to start the control process. Future activities include linking public health agencies with the USEF/USHJA and developing a model infection control plan that is specific to personal horse farms and horse show grounds.
