Diabetic Foot Infections
There are an average of 2 to 6 microorganisms cultured from diabetic foot ulcers; the organisms typically include a combination of aerobic Gram-positives (s. aureus, streptococci, enterococci), aerobic Gram-negatives (including Pseudomonas spp.), and anaerobes, especially B. fragilis.
Most common for animal bites is Pasturella multocida, an aerobic Gram-negative rod. Other organisms include steptococci, staphylococci, Moraxella spp., and Neisseria spp. Human bites are normal oral flora including Streptococcus spp. (especially viridans streptococci and S. pyogenes), S. aureus, Eikenella corrodens, and anaerobes.
