[Outbreak of Staphylococcus aureus mastitis in a dairy herd: A case report]

The report describes an outbreak of Staphylococcus aureus mastitis in a dairy herd. The risk assessment included the analysis of data from milk recordings, bacteriological milk cultures, clinical mastitis records and influence of infected status on the culling risk of affected animals, as well as an evaluation of the milking routine. The milking routine and the treatment protocol of animals with Staphylococcus aureus infection were identified as possible risk factors. The implemented measures included changes to the milking routine, a different treatment protocol for infected animals, and culling and segregation of infected animals to reduce overall prevalence.
