Bacteriology And Antibiotic Susceptibility Of Wound Infections In A Teaching Hospital, Bengaluru

Breach in the skin with exposure of subcutaneous tissue due to trauma, surgeries, burns, diabetic ulcers, etc. is known as a Wound. Successful invasion and proliferation by either one or more species of microorganisms will result in the infection of wound which may result in formation of pus. Infection can be due to either endogenous or exogenous bacteria. AIMS: To find the pattern of the bacterial isolates and their susceptibility patterns from the wound samples. METHODS AND MATERIALS: A total of 420 patients with wound infection were included in the study. All the bacterial isolates were isolated and identified according to the standard microbiological techniques. Antimicrobial susceptibility testing was done by Kirby Bauer disc diffusion method. RESULTS: 327 bacterial isolates were isolated and identified from 442 specimens from 420 patients. Gram negative bacteria were predominant followed by gram positive bacteria. Staphylococcus aureus was predominant in gram positive organisms. Escherichia coli were predominant in gram negative organisms. Meropenem was the most sensitive antibiotic for gram negative bacteria and linezolid was the most sensitive antibiotic for gram positive bacteria. CONCLUSION: The successful management of wound infection depends on the knowledge of the most prevalent organisms and their antibiotic susceptibility profile along with infection control practices.
