Identification of bacteria from a non-healing diabetic foot wound by 16 S rDNA sequencing.

Approximately 10-20% of diabetic foot wounds fail initial antibiotic treatment. It is generally believed that several bacterial species may be present in these types of wounds. Because some of these organisms cannot be easily cultured, proper identification is problematic and thus, appropriate treatment modalities cannot be applied. This report examined the bacterial flora present in a chronic diabetic foot wound that failed antibiotic treatment. A tissue sample was collected from the base of the wound and used for standard microbiological culturing. DNA from the sample was used to amplify bacterial 16 S rDNA gene sequences and a library of these sequences was made. The clones were placed into two major groups on the basis of their melting temperatures. Representatives of these groups were sequenced, and information was used to identify the bacteria present in the wound. The culture-based method identified a single anaerobic species, Bacteroides fragilis. The method employing rDNA sequencing identified B. fragilis as a dominant organism and Pseudomonas (Janthinobacterium) mephitica as a minor component. The results indicate that rDNA sequencing approach can be an important tool in the identification of bacteria from wounds.
