Abstract:
The incidence of Staphylococcus aureus infections are being common in veterinary field. This study was an attempt to know the antibiotic sensitivity pattern of the S. aureus in the samples collected from Hyderabad. Samples comprising were 240 (30 each of raw milk, pasteurized milk, paneer, cheese, curd, khova, ice cream and pedha) samples, from which the colonies were isolated and grown in S. aureus selective mannitol salt agar plates. The antimicrobial sensitivity pattern of seven antibiotics was evaluated in this study. The antibiotics selected for the study were erythromycin (15 µg), Pencillin-G (25 µg), Ampicillin (10 µg), Oxacillin (1 µg), Ciprofloxacin (5 µg), Gentamycin (10 µg), Methicilin (10 µg), Streptomycin (10 µg), Vancomycin (30 µg) and Tetracyclin (30 µg). The maximum inhibitory zone was shown by Gentamycin (88%), followed by Ciprofloxacin (86%) and Erythromycin (64%) and the resistance was the maximum towards Pencillin G (98%) and Ampicillin (88%). This organism was intermediately resistant to Vancomycin (26%) and Streptomycin (14%). Hence it could be concluded that Gentamycin is the best cost effective drug with maximum inhibitory zone against S. aureus infections among the nine antibiotics studied.
