Infections in diabetic foot ulcers.

ABSTRACT

Foot ulcers and infections are common in diabetic patients. A 30-month-long descriptive study was conducted in our hospital in which we analyzed microbiological isolates of all patients admitted with diabetic foot infections. The predominant flora identified were Staphylococcus aureus and coagulase-negative Staphylococcus, followed by Enterococcus spp., Streptococcus spp., and enterobacteriaceaes. In 27 positive cultures (42%) polymicrobial flora were found. There were only 5% anaerobic bacteria. There appears to be a relationship between the sample collection system and microbiological isolates.
