Bacillus Anthracis. Clinical microbiologists are sentinels for recognition of a bioterrorist event, especially involving microorganisms such as B. anthracis.Even though this organism is rarely found, sentinel laboratory protocols require ruling out the possibility of anthrax before reporting any blood, CSF, or wound cultures in which a large gram-positive aerobic rod is isolated.
