Methicillin Resistant Staphylococcus aureus (MRSA) is an infectious zoonotic and nosocomial pathogen that may be transmitted via direct contact with contaminated surfaces. The purpose of this research was to determine which human and equine contact surfaces in a veterinary teaching hospital were contaminated with MRSA. This research was performed in a large veterinary teaching hospital that receives over 1,200 equine patients annually. Swabs and Swiffer® were used to systematically sample pre-selected human and equine contact surfaces in three target surveillance sections of the hospital, collecting an average of 65 samples per month for a period of 12 months. The samples were then tested to detect the presence of MRSA. Of the contact surfaces sampled 8.5% (66/770) tested positive for MRSA, with an equal proportion observed between human contact surfaces (9.7%, 43/444) and equine contact surfaces (7.0%, 23/326) (p-value 0.19). The top three human contact surfaces contaminated with MRSA were the computers and keyboards (16.6%, 4/24), countertops and cabinets (11.4%, 16/140), and the doors (9.71%, 10/103). Among the equine contact surfaces the feed and water buckets (16.6%, 2/12), surgery tables and mats (15.5%, 7/45), and a pooled sample of halters, hay-bags and muzzles (11.1%, 4/36) had the greatest number of MRSA positive results. Of the MRSA isolates identified in this study 39.3% (26/66) were multi-drug resistant (MDR) with resistance to six classes of antibiotics including beta-lactams of the isolates analyzed genotypically the majority carried SCCmec type IV (34/39). These results are of importance due to the potential occupational risk to the staff and students for community-associated MRSA infections, as well as the possibility of nosocomial equine infections.
