Objective: To investigate the spread of methicillin-resistant Staphylococcus aureus (MRSA) isolated from a cluster of clinical cases at a veterinary hospital by molecular epidemiological techniques.
Methods: Antimicrobial susceptibility testing, spa typing, multilocus sequence typing and pulsed-field gel electrophoresis were used to compare 16 isolates of MRSA. Four isolates were cultured from clinical cases thought to be involved in the cluster. A single isolate that was unrelated to the cluster and the remaining 10 isolates were obtained from nasal swabs submitted by staff and students during a subsequent survey of MRSA carriage.
Results: Isolates from four clinical cases and an isolate obtained from a staff member were the same strain of MRSA. Some key risk factors associated with transmission of MRSA within veterinary hospitals were identified.
Conclusion: The information provided by these techniques was invaluable in developing procedures and identifying risk factors to help reduce the effect of future outbreaks within veterinary hospitals.
