MRSA (methicillin resistant staphylococcus aureus) is an antibiotic-resistant organism which can cause skin infections in humans. New reports now show that the infection can be passed from human to animal, including dogs, cats, and horses. The bite from an infected animal can then spread the infection to others. It has been reported that the bite of animals who do not carry the infection may also cause a wound infection in people who carry the bacteria on their skin.

Why is it a concern? MRSA is a form of staph infection which has become resistant to our common arsenal of antibiotics. This does not mean that the infection cannot be treated; these infections are simply harder to treat. Generally, MRSA causes skin infections which result in boils or pimples. However, it can also cause infection elsewhere, such as in the lungs, the urinary tract, or the bloodstream. In some cases, MRSA can be fatal--most often, it simply causes a stubborn skin infection that can be difficult to clear.

MRSA can be spread by contact; in fact, about 1% of the population is colonized with the infection but remain asymptomatic. The infection can be spread by touching an infected person, or by handling an object which is contaminated with the bug. Pets can carry the bug as well, spreading it to others through bites most commonly. MRSA is becoming more common in the community, whereas it used to be present mainly in people who are residents of nursing homes, hospitals, or other care centers. The rapid rise in MRSA infections has several authorities alarmed.

How can you keep both you and your pet safe? Have your pet seen regularly by a qualified veterinarian. If you are bitten by an animal, you should see your physician for advice.
