Mastitis in Slaughtered Dairy Cows




Abstract
The udders of 28 culled dairy cows were removed at slaughter and bacteria isolated. Isolations of major known mammary pathogens comparised Staphyloccus sp. (40.7%), non-identified Gram’s negative rods (33.2%) and E.coli (7.4%). In the mixed infection, Staphylococcus sp. was most frequently involved.
Drug sensitivity tests were performed on several bacterial species by disc method. These tests indicated that the microorganisms isolated from clinical mastitis of dairy cows were more resistant to antimicrobial agents than the organisms isolated from milk samples.
