This Gram-stained micrograph of Clostridium botulinum Type-A in thioglycollate broth was incubated for 48hrs at 35°C. These are Clostridium botulinum Type E colonies displaying an opaque zone grown on a 48hr egg yolk agar plate; Mag. 1.9X. These are cultures of the anaerobic bacterium Clostridium perfringens grown on an egg yolk agar plate. These Clostridium perfringens colonies were cultured on a half-antitoxin plate. These Clostridium perfringens colonies were cultured on a SPS (Sulfite Polymyxin Sulfadiazine) agar plate. The Clostridium difficile enterotoxin, CPE, is the principal toxin involved in C. difficile foodborne illness. This micrograph of the bacterium Clostridium difficile is made from an impression smear of 72hr anaerobe blood agar. These are Clostridium sporogenes colonies grown on a 48hr blood agar plate; Magnification 15X. This is a close up of contaminated Jalapeño peppers involved in an outbreak of botulism in Pontiac, Michigan, April, 1977. This is lymph node impression smear reveals B. anthracis on the left, with normal, non-infected tissue on the right. This was a blood agar culture plate growing B. anthracis and other soil flora. This agar culture plate is growing Bacillus anthracis colonies. This is a brain section through the ventricles revealing an interventricular hemorrhage. This is a photomicrograph of lung tissue infected with Bacillus anthracis bacteria. This was a blood agar culture plate growing B. anthracis and other soil flora. This man was "made up" so as to show symptoms of cutaneous anthrax due to B. anthracis. This man was "made up" so as to show symptoms of cutaneous anthrax due to B. anthracis.
