The Gram stain usually shows a polymicrobial flora with aerobic gram-negative rods and positive cocci when polymicrobial infection is present. However, in many cases, a single organism (eg, GABS, methicillin-resistant Staphylococcus aureus [MRSA], Clostridium) may be causing the infection, while cultures, including blood cultures, may spuriously reveal a polymicrobial infection. The presence of plentiful cocci on the Gram stain is characteristic of necrotizing infection, whereas cocci are rarely identified in erysipelas. [78]
