Abstract
A total of 110 surface swabs were taken from skin of burned and post burn wounded patients. Infected swabs from burned patients were found to be 62.8% and 63.6%,while post burn wounded patients were 66.7% and 69.2% in male and female patients, respectively. The burned and post burn wounded patients were infected with bacteria in the order of gram negative bacilli > gram positive cocci>gram positive bacilli. Pseudomonas aeruginosa, proteus mirabilis, bacillus megaterium and bacillus cereus showed the highest proteolytic activity. The effect of cultivation condition,different media, incubation time, incubation temperature, pH, metal ions, inhibitors and different doses of gamma radiation on the proteolytic activity of the tested bacterial isolates showing the highest proteolytic activity were studied. The tested bacterial isolates showed susceptibility to some antibiotics and showed resistance to the others. The effects of gamma radiation on the tested bacteria and on the susceptibility of the tested bacteria isolates to antibiotics under test were studied
