Study on bacterial flora of burn wound infection: A need for microbiological surveillance in burn units

75% of the mortality associated with burn injuries is related to infection The aim of the present study was to identify the bacterial profile of burn wound infection (BWI) in our setting and determine their susceptibility pattern to commonly used antibiotics.This prospective study was conducted over a period of one year in a teaching tertiary care hospital, Chennai. A total of 100 patients with burns of total body surface area (TBSA) of 20% to 40% were included. Three wound swabs on 1st , 4 th and 7th day were collected aseptically and processed. | Int.J.Curr.Microbiol.App.Sci 2017 6 5 807-815 International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 6 Number 5 2017 pp. 807-815 Journal homepage http www.ijcmas.com Original Research Article https doi.org 10.20546 ijcmas.2017.605.091 Study on Bacterial Flora of Burn Wound Infection A Need for Microbiological Surveillance in Burn Units T.

A total of 100 patients with burns of total body surface area TBSA of Bacterial Flora 20 to 40 were included. Three wound swabs on 1 st 4th and 7th day were collected Burn Wound aseptically and processed. Among the 274 samples collected 191 swabs revealed Infection growth while 83 showed no growth. Overall isolation rate was found to be Microbiological 69.7 and was predominantly monomicrobial with Gram positive cocci in early swabs. Surveillance. Subsequent swabs showed 100 colonization with a shift to polymicrobial infection with predominant isolation of Gram negative bacilli. The most common isolate was Article Info Pseudomonas aeruginosa 35.84 followed by Klebsiella pneumoniae 27.30 Accepted Acinetobacter spp. 20.13 Staphylococcus aureus 8.87 Escherichia coli 2.38 . 04 April 2017 Gram negative bacteria were found to be highly susceptible to Imipenem and Piperacillin Available Online Tazobactum. Staphylococcus aureus was 100 sensitive to Linezolid. .
