One hundred ninety suspicious milk samples from dairy cows in cattle husbandry farms in Ilam were examined by California Mastitis Test (CMT), then positive sample as a mastitis case selected to exam for bacterial agent of infection. Samples contaminated with staphylococcus aureus separated determine their sensitivities against different antibiotics.

Of 190 samples, 56 and 2 had subclinical and clinical symptom, respectively. Of 56 case 11 were positive for staphylococcus aureus. The sensitivity test indicated 91%, 82%, 73%, 73%, 45%, 18%, 0%, and 0% of staphylococcus aureus isolated were sensitive against Enrofloxacin, Trimethoprim, Tylosin, Lincomycin, Tetracycline, Ceftriaxone, Penicillin,and Ampicillin, respectively. Histopathological assess indicated degeneration of epithelial, hyperplasia of epithelium, meteplasia squamous to columnar cells in different part of breast tissue.
