Bacteriological Profile and Antibiotic Resistance Pattern of Pathogens Causing Pyogenic Infections At A Tertiary Care Hospital in Central India

Abstract

Background: Pyogenic infection is a bacterial infection that leads to the formation of pus. Antibiotics are routinely prescribed to treat these pyogenic bacterial infections, but their toxicity poses a severe threat. It is important to know the antimicrobial resistance profile of such pathogens for proper management of the patients. Objectives: To determine the bacteriological profile and antibiotic resistance pattern of pyogens. Patients and Methods:In this cross sectional study, a total of 678 pus samples were received and processed for aerobic culture from various departments. Standard techniques were used to identify isolates from positive pus cultures, and CLSI standards were used to identify antimicrobial susceptibility patterns. Results: Out of the 678 samples, 347 (51.18%) showed growth of pathogenic bacteria. Two hundred seventeen two (40.11%) Gram positive cocci and 75 (11.06%) Gram negative bacilli isolates were identified. Staphylococcus aureus was the most common isolate (57.5%). Most of the isolates were highly resistant to commonly prescribed antimicrobial drugs like Amoxycillin clavulanate. Most of the gram positive isolates were susceptible to vancomycin, linezolid, and teicoplanin. Most of the Gram-negative isolates were sensitive to imipenem. Conclusion: Microbiological profile findings of pus culture isolates as well as their pattern of antimicrobial resistant may aid in the formulation of antibiotic policies for pyogenic infections.
