A study was carried out to evaluate the antibiotic sensitivity of Staphylococcus aureus isolated from different raw milk samples. Isolation and identification of S. aureus were done from 5 types of dairies raw milk samples. A total of 125 milk samples from dairies were cultured for incidence of S. aureus. S. aureus was isolated from a total of 4 (3.2%) of the 125 milk samples. The antibiotic susceptibility pattern of S. aureus isolated from different raw milk samples was performed. Staphylococcus aureus strains were found to be susceptible, intermediate and resistant against different antibiotics. Strain1 was found to be susceptible against gentamycin and cotrimoxazole, intermediate against chloramphenicol, tetracycline and cephalothin, and resistant against ampicillin and methicillin. strain2, starin3 and strain4 were found to be susceptible against Gentamycin, Chloramphenicol and tetracycline, and Resistant against Ampicillin, Methicillin, Cotrimoxazole and Cephalothin. The present study provides preliminary information on incidence of antibiotic sensitive S. aureus as milk contaminates. The antibiotic residue in raw milk samples were analyzed in terms of Ampicillin by using TLC. According to the total number of 125 samples analysed, the ratio of contamination with antibiotics was detected as 0.8%.
