For example, the minimum standards for the evaluation of deep wound cultures require adequate procedures for the collection, recovery and identification of clinically relevant pathogens, which includes aerobic, facultatively anaerobic, and strictly anaerobic organisms. Anaerobic organisms may be significant isolates from other specimen types as well. Suggested media for anaerobes include an anaerobic blood agar plate, a medium that inhibits gram-positive and facultative gram-negative bacilli such as KV blood agar, a differential or selective medium such as BBE (Bacteroides bile-esculin), and a gram-positive selective medium (colistin-nalidixic acid blood agar or phenylethyl alcohol blood agar). Provisions for adequate anaerobic incubation, with monitoring of the anaerobic environment, must be available. If specimens are referred to another laboratory, they must be transported in an expeditious fashion under appropriate conditions.
