Loeffler A, Pfeiffer DU, Lindsay JA et al: Prevalence of and risk factors for MRSA carriage in companion animals: a survey of dogs, cats and horses, Epidemiology and infection 139:1019, 2011.
Methicillin resistant Staphylococcus aureus (MRSA) is a significant health concern in people. Little is known about carriage of these bacteria in companion animals. The investigators tested healthy as well as ill animals at various animal facilities in the greater London area for MRSA. Out of nearly 1700 animals tested, including 540 cats, only 26 animals were found to be colonized with MRSA; of these, 8 were cats. In evaluating risk factors among animals for carriage of MRSA, the investigators found that it is rare among companion animals. They also concluded that animals from which MRSA can be cultured are likely contaminated from their human companions, and do not serve as reservoirs for the bacteria. [MK]
