Antibiotic sensitivity of bovine staphylococcal and coliform mastitis isolates over four years.
Eight hundred and forty-eight strains of Staphylococcus aureus and coliforms isolated from milk samples taken from cows with clinical or subclinical mastitis were tested for their sensitivity to a range of antibiotics, comparing strains isolated in 1984, 1985, 1986 and 1987. The only increase in the proportion of resistant strains occurred with coliforms resistant to ampicillin and neomycin.
