Methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-resistant S. pseudintermedius (MRSP) are important causes of infection in pets, and are resistant to many different antibiotics. It’s therefore very important that these bacteria are cultured and tested in a lab to determine what antibiotics may be effective.  Even then, choosing an effective medication can be difficult due to

All these species can come in ‘methicillin-resistant’ forms that are resistant to many antibiotics, but some of these species are of greater concern than others. The main species of

Many people in the horse world have heard the hype about methicillin-resistant Staphylococcus aureus (MRSA) in horses. MRSA can cause infection in horses, just like it can in people, dogs, cats and many other animals.

This is a question that I get on a regular basis.
