Prevalence of methicillin-resistant on hand-contact and animal-contact surfaces in companion animal community hospitals.

Methicillin-resistant (MRSP) is an important companion animal pathogen, but few published studies have evaluated its epidemiology in primary care settings. This study determined MRSP prevalence on hand- and animal-contact surfaces in 11 small animal primary care hospitals in Washington and Idaho, USA. Overall, MRSP was isolated from at least 1 sample from 7 of 11 hospitals (64%) and from 36 of 374 total samples (10%) with no difference in prevalence between hand- and animal-contact surfaces ( = 0.51). Strain typing by pulsed-field gel electrophoresis indicated high within-hospital similarity of MRSP strains, but minimal similarity between strains from different hospitals. Indistinguishable MRSP strains were present on handand animal-contact surfaces within individual hospitals. A questionnaire was administered to a representative from each hospital. Respondents reported that animal-contact surfaces were cleaned and disinfected more frequently than hand-contact surfaces ( < 0.001). Improving hand hygiene and disinfection of hand-contact surfaces may decrease exposure of veterinary patients to MSRP.
