Occurrence of MRSA in dairy goat herds

Methicillin-resistant Staphylococcus aureus (MRSA) is a widespread zoonotic bacterium of increasing clinical importance. In humans, it may cause infections that are difficult to treat due to multiresistance. Although animals may also develop MRSA infections, they are most often healthy carriers, and this bacterium can occur in many animal species. MRSA has previously been detected in goat herds in Sweden, and with a high occurrence of mecC-MRSA in the goats, but only few herds were investigated and most of these herds were non-milk-producing. Interestingly a recent Austrian study indicated an association between mecC-MRSA and goats with 8% of the goats being positive in that study. The prevalence of MRSA among dairy goat herds in Sweden is not known. The aim of the present cross-sectional study was therefore to study the prevalence of MRSA in 22 dairy goat herds.

A total of 22 bulk milk samples and pooled swabs from nose, mouth and perineum from 115 goats, were collected for bacteriological investigation. No samples were found positive for MRSA.

To conclude, there are no indications of an emerging spread of MRSA in Swedish dairy goat herds.
