Abstract :

 Aim & Objective– To study the rate of isolation of aerobic bacteria in patients with burn wounds, their changing pattern of colonization with hospital stay as well as the sensitivity pattern.

Material & methods– Over a period of one year in a prospective study for 100 patients, two swabs were collected from the infected area of the burn wound every week from the date of admission. These swabs were subjected to direct microscopic examination as well as plated on the suitable culture media. The organisms isolated were identified according to standard protocol for identification and antibiotic sensitivity was performed.

Results– From 161 wound swabs by aerobic bacterial culture, 140 strains were isolated. In the first week of the total swabs, 32.1% of cultures were sterile and percentage of sterile swabs reduced drastically in the subsequent weeks. Acinetobacter spp. (42.2%) was the most commonly cultured organism followed by Pseudomonas spp. (18.6%) and Klebsiella spp. (17.9%). Staphylococcus aureus accounted for only 7.9% of isolates and most of these were methicillin resistant. The isolates of Acinetobacter spp. and Klebsiella spp. showed high degree of resistance to aminoglycosides, third generation cephalosporins and also to carbapenems. Imipenem, colistin and tigecycline were the most effective antibiotics for Gram negative bacteria.

Conclusion– Burn wounds destroy the most important defense mechanism of the body and has high propensity for infection particularly harboring multi drug resistant organisms.
