Isolation, Identification and Susceptibility Patterns of Bacteria in Infected Wounds of Diabetic Patients

Abstract

This study was conducted in order to identify the bacterial pathogens associated with diabetic wounds and determining their antibiotic susceptibility patterns. A total of 50 diabetic patients were introduced in the present study that was conducted during June - August 2012. It has been found that wounds are highly infected by aerobic and anaerobic bacterial types; Different species were isolated from infected wound swab. 7 different species were isolated from the specimens they were staphylococcus aureus 9 (18%), E. coli 8 (16%). Pseudomonas aeroginosa 14 (28%). Proteus vulgaris 7 (14%). Streptococcus pyogenes 4 (8%). Klebsiella pneumonia 4 (8%) and Clostridium spp 2 (4%). Pseudomonas aeroginosa bacteria- was a predominant pathogen in diabetic wound infections. Most isolates were found to be sensitive to most antibiotics used and their susceptibility to amino glycoside was found to be more than 60% except Pseudomonas aeroginosa which is resistant. Gentamycin and streptomycin were found to be the most effective antibiotics against most Gram negative and Gram positive organisms.
