Abstract:
A total of 79 strains of staphylococci isolated from milk of mastitic cows in different Ninevah localities was divided into three groups based on biochemical activity. Group A was classified as Staphylococcus aureus . The resistance of these strains to antibiotics was: penicillin, 47.17%, streptomycin, 20.75%; erthromycin, 9.43%; and chloramphenicol, 5.66%. Most of the strains were resistant to the international phage set but were sensitive to phages 78 and 102 of the bovine phage set. Five strains produced enterotoxin C and two strains produced enterotoxin D.
