Anaerobic Infections.

Oxygen-sensitive anaerobic bacteria comprise the largest group of organisms among the human endogenous microflora. The oral cavity, the vagina and the colon are areas where the obligate anaerobes are predominant and can be isolated in high numbers. Clinical clues that indicate anaerobic sepsis include a putrid odor of the exudate and evidence of abscess, necrosis or associated gas formation. A Gram stain is highly valuable in early identification. Surgical drainage and appropriate antibiotics are essential.
