Clinico Microbiological Spectrum of Diabetic Foot Infections
Journal Title: Scholars Journal of Applied Medical Sciences - Year 2018, Vol 6, Issue 3
Abstract
Abstract: Diabetic foot infections are a common cause of morbidity and mortality. This study was undertaken to study the microbiological flora of diabetic foot ulcers and to assess the in vitro antibacterial susceptibility of the causative bacteria. This was a prospective observational study conducted in which 247 wound swabs collected from patients with diabetic foot infection. All collected specimens processed using standard microbiological techniques. Disc diffusion method was used to find out the susceptibility of bacterial agents. 209 specimens yielded microbial growth on culture media. Monomicrobial growth accounted for 74.06%. Staphylococcus aureus was the predominant organism isolated in which MRSA was 27%. Second common pathogen was Pseudomonas aeruginosa. All Gram positive strains were found sensitive to linizolide. Imipenem showed good susceptibility against Gram negative bacilli. Candida was the only fungi isolated. Staphylococcus aureus was isolated predominantly from diabetic foot infections. Monomicrobial growth was seen in 177 patients and accounted for 74.06%. Polymicrobial growth was seen in 62 patients and accounted for 25.94%. The most common combination was S. aureus and Candida species. Majority of Gram positive and Gram negative isolates were susceptible to linezolide and imipenem respectively.
