Abstract

Background: Antimicrobial resistance is a global health problem and the number of organisms developing resistance to commonly used antibiotics is increasing.

Objective: The study was aimed to find out the pattern of common organism isolated from wound swabs and pus with their antibiogram.

Methods: This observational study was conducted from September 2018 to January 2019 in a tertiary care hospital in Dhaka, Bangladesh. Culture and sensitivity tests were done for wound swabs and pus samples. Data regarding information of the patients, isolated organisms and culture and sensitivity reports were collected from the records of the department of microbiology.

Results: Out of 1709 samples, 72.0% yielded growth of organisms of which 86.4% were gram negative and 13.6% were gram positive bacteria. Pseudomonas spp was the most commonly (43.8%) isolated organism from both wound swab and pus samples followed by Escherichia coli (16.6%), Staphylococcus aureus (11.8%), Klebsiella spp (9.8%). Among gram negative bacteria, 14.9% were ESBL producing organisms and Klebsiella spp were the most commonly isolated ESBL producers. Most of the bacteria showed high resistance to commonly used antibiotics. Gram negative bacteria were mostly resistant to amoxicillin followed by fluoroquinolones, co-trimoxazole, and cephalosporins whereas colistin, carbapenems and piperacillin/tazobactum were the most effective drugs against them. Majority of gram positive bacteria were resistant to fluoroquinolones and co-trimoxazole but 100% Staphylococcus aureus were sensitive to vancomycin, followed by linezolid (98.0%) and teicoplanin (86.0%) and 32.0% of them were Methicillin resistant (MRSA).

Conclusion: The susceptibility pattern shows that some common antibiotics, especially antibiotics of oral form have very limited usefulness in treatment of infections and also highlight the need for regular reporting and antibiogram guided antibiotic prescription.
