Pets & MRSA

Methicillin-resistant Staphylococcus aureus (MRSA) is a methicillin resistant bacterium that causes infection in animals including humans and pets. MRSA is one of the most common causes of soft tissue and skin infections in humans. It has also been identified in dogs, cats, pigs, cattle and horses.

Colonization

• MRSA bacteria are carried on the skin or in the nose of healthy pets or humans. Animals carrying the bacteria that do not show any symptoms of infection are referred to as "colonized" while animals with the bacteria that show symptoms are "infected."

Infection

• An animal infected with MRSA may have multiple symptoms ranging from minor skin infections to major wound infections. The bacterial can also result in blood infections, heart problems, pneumonia or meningitis.

Transmission

• Transmission of the bacteria happens by physical contact. Originally it was believed that transmission was conducted only from human to pet, but now it is believed to be transmitted either from human to pet or pet to human.

Animals at Risk

• Any animal with a weakened immune system has a higher risk for infection by MRSA. Pets with owners who have weakened immune systems are at higher risk, as are animals that frequent hospitals or nursing homes as therapy pets.

Treatment

• Pets suspected to have MRSA colonization or infection should be examined by a veterinarian to determine if they have the bacteria. Skin infections are typically treated with topical cream. Your veterinarian can suggest optional antibiotics for more advanced infections.
