Khulood Khalaf Jabbar, Ammani K., Ganesh Dama and Balasubramanian Sathyamurthy*
In the current study, the antimicrobial activities of some of the commercially available Antibiotics were evaluated against selected clinical Isolates. The Isolates (Test organisms) used were Staphylococcus aureus, Enterobacter aerogenes, Salmonella, Streptococcus pyogenes. These bacterial cultures were grown in Trypticose soya broth & treated with drug (Test compounds) viz., Cotrimoxazole, Tetracycline, Amoxicillin, Cefixime, Erythromycin, Ciprofloxacin, Azithromycin & Gentamicin at different concentrations. After incubation, the antimicrobial activity was evaluated by measuring the inhibition zones.
Keywords: Antibiotics, Clinical Isolates, MBC, MLC, Test compounds, Trypticose broth, Agar plates.
