Occurrence of MRSA in dairy goat herds

Published 2020-01-10
Methicillin-resistantStaphylococcus aureus (MRSA) is a widespread zoonotic bacterium ofincreasing clinical importance. In humans, it may cause infections that aredifficult to treat due to multiresistance. Although animals may also developMRSA infections, they are most often healthy carriers, and this bacterium canoccur in many animal species. MRSA has previously been detected in goat herds inSweden, and with a high occurrence of mecC-MRSA in the goats, but onlyfew herds were investigated and most of these herds were non-milk-producing. Interestinglya recent Austrian study indicated an association between mecC-MRSA andgoats with 8% of the goats being positive in that study. The prevalence of MRSAamong dairy goat herds in Sweden is not known. The aim of the present cross-sectionalstudy was therefore to study the prevalenceof MRSA in 22 dairy goat herds.

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

Toconclude, there are no indications of an emerging spread of MRSA in Swedish dairygoat herds.
