MRSA in Cats in Animal-Assisted Therapy Programs

Coughlan K, Olsen KE, Boxrud D, et al. Methicillin-resistant Staphylococcus aureus in resident animals of a long-term care facility. Zoonoses and Public Health 2010;57:220-226.

Many hospitals and long-term care facilities allow visitation by pets or animal-assisted therapy programs for benefit to the elderly or chronically ill patients. Concern exists regarding transmission of infectious agents between pets and patients. Antibiotic-resistant bacteria, such as methicillin-resistant Staphylococcus aureus (MRSA), can lead to life-threatening illness, but little is known about potential carriage of these bacteria in animals at long-term care facilities. The investigators collected nasal swab samples from 12 animals (one dog, 11 cats) weekly for eight weeks at a facility, and characterized the S. aureus isolates for antibiotic resistance. They found two of the 11 cats were colonized with MRSA (one cat in 5/8 samples, the other in 2/8 samples). All isolates were health care-associated strains. They concluded that animals at these facilities may acquire MRSA from patients, as human cases on the floors visited by these cats had occurred. It is believed that carriage of MRSA by animals is transient, thus these cats will likely clear the bacteria. While this study presents only a brief snapshot at one facility, these findings demonstrate the need for good hand hygiene, as well as for monitoring resident animals at these facilities. The benefits of human-animal interactions at these facilities far outweighs the potential risks, but guidelines should be in place at these facilities to minimize the risk for patients and staff.

Methicillin-resistant Staph infections in Cats

Faires MC, Tater KC, Weese JS: An investigation of methicillin-resistant Staphylococcus aureus colonization in people and pets in the same household with an infected person or infected pet, J Am Vet Med Assoc 235:540, 2009.

Methicillin resistant Staphylococcus aureus (MRSA) is an important pathogen that has been identified in humans, as well as dogs and cats. MRSA from humans may cause infections in pets, and pets may be sources of MRSA for human infection. In order to lessen the risk of transmission of MRSA between humans and pets, a better understanding of the role, if any, of pet-to-human transmission is needed. This report describes an investigation of the prevalence of MRSA in people and their pets within the same household in which MRSA infection was known to exist, and to compare the isolates identified within a household. Households in which MRSA infection had been identified in a pet within the past month (part 1), as well as households in which one or more persons had experienced >1 MRSA infection within the past year (part 2) were included. Nasal specimens from humans and nasal and rectal swabs from pets were collected and cultured for MRSA. In households with MRSA, both humans and pets, including cats, were found to be infected, and the isolates were indistinguishable whether from humans or pets. This indicated that cross-species infection could occur, though the direction (human to pets or vice versa) was not known. The authors speculate that humans were the most likely source for the pets, rather than the reverse as the isolates were related to community-associated human strains. In addition, the affected pets were not in contact with other animals, and thus likely contracted the MRSA from their human owners. [MK]
