Pseudomonas aeruginosa was the most predominant species in 40% of cases followed by Staphylococcus aurues in 31% of cases. Escherichia coli was present in 12% of cases and Proteus and Klebsiella in 5% each. Antibiotic sensitivity for Staphylococcus aureus was found to be sensitive to amoxiclav, Cefazolidone, erythromycin, azithromycin, clindamycin, netilmycin and gentamycin.
