RAPID DETECTION AND ISOLATION OF STAPHYLOCOCCUS AUREUS FROM MASTITIC MILK

摘要

Staphylococcus species are common etiologic agents of mastitis in cows. They are also capable of producing enterotoxin and are important in outbreaks of foodbome illness. Mastitis caused by Staphylococcus aureus infection in herds is generally indicated when somatic cell counts (SCC) in bulk tank milk reach 500,000 -1,000,000 cell/mL. However, chronic S. aureus infections are difficult to identify and treat using only bulk tank SCC, and isolation of the pathogen from mastitic milk is necessary for determining the infection status of suspect cows.
