New Strain Of Horse-Specific MRSA Identified In French Study

A new horse-specific strain of methicillin-resistant Staphylococcus aureus (MRSA) has been prevalently found in France, according to researchers. MRSA is a bacterial infection that can affect various parts of the body and can be difficult to treat because of its natural resistance to many commonly used antibiotics.

Researchers took 130 samples of MRSA collected between 2010 and 2015 from cats, dogs and horses infected with the disease. The cats and dogs were mostly infected by a strain of the disease that was typically reported in humans, while the equines were largely infected with a strain called CC398-IV-t011, which was independent from the human form of MRSA.

This indicated that the form of MRSA being currently found in horses in France, is uncommon in the human population.

The main form of MRSA affecting horses in North America is CC8-IV-USA500. While it was found in French horses between 2011 and 2013, it has not been diagnosed in horses in France since 2014.

The prevalence of this new form of MRSA in horses in France may come with some benefits, as this form of the illness is less prevalent to some antibiotics than other forms of the disease.
