Status of ESBL Producing Bacteria Isolated from Skin Wound at a Tertiary Care Hospital in Bangladesh

摘要

Background: ESBL producing bacteria are increasing with an alarming rate with a wide range of infections. Objective: The purpose of the present study was to see the status of ESBL producing bacteria isolated from skin wounds. Methodology: This cross sectional study was conducted in the Department of Microbiology at Mymensingh Medical College, Bangladesh from January 2011 to June 2011 for a period of 6 months. All the patients, at any age with both sexes presented with skin wound infection, were taken as study population. Wound swab was taken from all patients. Specimens were processed and bacteria were isolated and identified according to standard procedure. The ESBL status was confirmed by double disc diffusion test (DDDT) and minimum inhibitory concentration (MIC) by agar dilution method by standard procedure according to Clinical Laboratory Standard Institute (CLSI). Antimicrobial resistance was done by disc diffusion method. Result: A total number of 84 wound swabs were taken of which the most common ESBL producing bacteria were Esch. coli (61.5%),?Proteus species (78.3%) and Klebsiella species (88.9%). All the isolates were sensitive to imipenem and nitrofurantoin followed by amikacin (92.9%). Conclusion: In conclusion, ESBL producing E. coli is the most common bacteria causing skin wound infection followed by Proteus species with a reduced sensitivity towards antibiotics.
