Methicillin Resistant Staphyloccocus Aureus (MRSA) is an infection that animals and humans can share; often referred to simply as "staph". MRSA is called a "superbug" because of its resistance to common antibiotics. Medical authorities cite three major causes of MRSA, the overuse of antibiotics in humans, antibiotics in our food and water sources and germ mutation. Sadly, MRSA has made a comeback recently and there have been several outbreaks in various parts of the country.

A less known, but documented source of MRSA, can be your family pet. The CDC has cited several cases of dog to human MRSA transfer since 2000 (more info: http://www.cdc.gov/ncidod/EID/vol10no12/04-0387.htm). Animals including dogs, cats, rabbits, horses, pigs, cattle and birds can carry MRSA, many without symptoms. The infection is spread through daily contact with an infected pet, and can be spread from an infected human to an animal as well.

The first symptom of MRSA is generally a small red bump or bumps; they may look like a boil or large pimple. The lesion can infect the tissue underneath it or it may grow to the point where it needs surgical draining. MRSA is carried naturally by a small percentage of the population, but in most humans it can develop into a very serious condition without treatment. If you develop a lesion that appears to be infected or is painful it's important to ask your doctor to perform a nasal or skin swab to test for MRSA before treatment. Common skin lesion treatment can exacerbate MRSA and can be life-threatening. It takes about 48 hours for a swab to be tested; however, in-office quick screen tests are becoming more available every day.

If you suspect your animal has MRSA their vet can perform a similar test. Animals generally deal with MRSA more efficiently than humans but your pet will need monitored, and all of your pets will likely need treatment.

The number one way to prevent a MRSA infection is to wash your hands properly and often. Always wash your hands after handling and feeding your animals or changing their bedding, use hot water and soap and scrub for at least thirty seconds using plenty of friction. Antibacterial soaps are not recommended as they are thought to contribute to the problem of superbugs. Disinfect your animal's habitat and bedding frequently, disposing of the waster properly.

MRSA is a serious infection but it doesn't have to be a reason to hold you back from owning an animal. Most animals don't carry MRSA and cross-infection can be prevented with proper hygiene and treatment.
