Isolation and Identification of Slime Forming Staphylococcus aureus from Raw Cow Milk and their Antibiotic Susceptibility Pattern

Staphylococcus aureus is an emerging pathogen from dairy animals that can form biofilms in the udder of cows affected by mastitis. The use antibiotics farms leads to a decrease bacteria, finally making healthy food. aim this study was determine occurrence, antibiotic susceptibility, and biofilm forming ability S. isolated cow milk. A total fifteen raw milk samples were collected Mohammadpur, Narayangonj, Savar, Bosila, Siddheshwari Norshingdi for isolation aureus. All highly loaded with staphylococcal count ranged 105 106 cfu ml-1. Biochemical tests (TSI, catalase, oxidase, motility, MR/VP etc.) performed confirmation Staphylococcal isolates. 100% resistance observed against oxacillin, erythromycin, cotrimoxazole, amoxicillin, cefixime vancomycin. In contrast these results, isolates showed sensitivity gentamicin ciprofloxacin. kanamycin tetracycline be variable. present reveals presence multidrug resistant Therefore, appropriate control measures like proper sanitation place where milking live, maintenance hygiene before after milking, using mechanical methods strict etc. are needed ensured.
