Your Dog and MRSA

Once upon a time, people thought that dog saliva had healing properties. This old adage probably stemmed from seeing dogs lick their wounds after injury. We now know that this is not the case. In fact, a dog's mouth contains many strains of bacteria. This bacteria generally causes no harm to the skin, but can cause infection if it enters an open wound - usually from a bite. As a vet tech, I have seem many co-workers develop infections from animal bites. I've had one or two bites myself that turned into minor infections. One of the most common of these bacteria is Staphylococcus aureus. Typically, a round of antibiotics will do the trick, though some serious infections require hospitalization with intravenous antibiotics. In short, animal bites are no fun.

Unfortunately, research has shown the emergence of a potentially life-threatening methicillin-resistant Staphylococcus aureus (MRSA) infections shared between pets and human handlers. MRSA infections are especially difficult to treat because they do not respond to the usual antibiotics. Most common are skin, soft-tissue, and surgical infections. MRSA infections in pets are often acquired from their owners and can may even cycle back and forth between pets and humans. Because they are drug-resistant, minor infections can easily turn into serious conditions like sepsis.

So, what does this all mean to you? First of all there is no need to panic. Second of all, don't banish your dog from the house. MRSA is not easily transmitted through normal contact - it is usually contracted through bites or scratches. Take measures to prevent dog bites, wash your hands frequently and keep your dog healthy. If you do get bitten or scratched by an animal, seek medical attention right away.

Cats can be affected by MRSA infections, too. Read about cats and MRSA from Cats Guide Franny Syufy:
