Isolation of antibiotic resistant Staphylococcus aureus isolates from house flies, Musica domestica (L.)

Present research was conducted to isolate, culture and identify Staphylococcus aureus from the external surface of the house fly, also to test the sensitivity of the isolated bacteria to different antibiotics. Laboratory culture and diagnosis showed that 11 (32%) samples were negative (no growth), whereas, 25 (68%) samples indicated positive results (growth). Laboratory diagnosis illustrated that S. aureus consisted the largest per cent 15 (60%) isolates in addition to other bacterial isolates such as Bacillus Spp., Escherichia coli and Pseudomonas aeruginosa. The results of the sensitivity test using nine types of antibiotics, found that S. aureus was resistant in varying proportions to the tested antibiotics (Oxacillin 100%, Gentamycin 40%, Tetracycline 66.7%, Erythromycin 73.3%, Cefixime 100%, Vancomycin 0.0%, Azithromycin 93.3%, Ceftriaxone 100%, Norfloxaclin 0.0%).
