Bacteriological Profile and Antibiotic Susceptibility Pattern of Pus Isolates in Patients Attending a Tertiary Care Hospital in Kolkata, West Bengal

Objective: Aim of the present study is to determine the bacteriological profile of pus samples and their antibiotic susceptibility pattern in patients attending a tertiary care hospital in Kolkata, West Bengal. Materials and methods: The present study is a prospective study done in a tertiary care hospital in Kolkata. The study was done for a period of one year. Pus samples received for diagnostic Microbiology was subjected to culture and antibiotic susceptibility testing. Results: Our study showed that out of the 690 pus samples received in the Microbiology Department, 442 were culture positive (64.05%). Out of them, Klebsiella pneumoniae was found to be the most predominant organism (29.05%), followed by Escherichia coli (21.5%), Pseudomonas aeruginosa (18.16%), Staphylococcus aureus (17.6%), Enterococcus species (10.6%) and Acinetobacter species (3.63%). Conclusion: The changing antimicrobial resistance pose a challenge in treating the pyogenic infections. Microbiological analysis and antimicrobial susceptibility of pus isolates serve as a useful tool for judicial and appropriate use of antibiotics. This can minimize the emergence of drug resistant strains in future.
