ABSTRACT

Objective: To determine the frequency of bacterial pathogens and their antimicrobial profile in diabetic foot infections.
Study Design: Cross-sectional study.
Place and Duration of Study: The study was conducted at the Department of Microbiology, Combined Military Hospital (CMH) Lahore, Pakistan from January 2022 to December 2022.
Methods Three hundred and forty-one samples with a history of diabetic foot infections were processed. Antibiotic susceptibility testing was done using the Kirby-Bauer Disk Diffusion technique for the commonly used antibiotics. Clinical and Laboratory Standard Institute Guidelines (CLSI) 2022 were used to interpret the result of susceptibility testing.
Results: Three hundred and forty-one clinical samples with bacterial isolates causing diabetic foot infections were processed. The most common organism isolated was Pseudomonas aeruginosa (25.5%). Gram-positive isolates where found most susceptible to vancomycin and linezolid while gram negative was most sensitive to meropenem.
Conclusion: In the current study gram-negative bacteria were found to be the main pathogens. Effective antibiotic therapy based on microbiological profiles will definitely improve clinical outcomes.
