Bacteria and Parasite A pathogenic psychrotroph that produces an enterotoxin. Aeromonas hydrophilia – A spore-forming, pathogenic bacterium that forms an enterotoxin. is an aerobic spore-former, unlike the common Bacillus cereus B. cereus – clostridium spore formers which are anaerobic. A common pathogenic bacterium that forms an enterotoxin. It needs very low levels (about 5%) of oxygen and too much Campylobacter jejuni – will inhibit growth, and about 10% carbon dioxide is required for growth. Campylobacter is the most common cause of food borne illness in the , commonly associated with diarrheal illness. A spore-forming, pathogenic bacterium that forms a neurotoxin when in an anaerobic environment. is a Clostridium botulinum C. botulinum – concern mainly in canned foods. A spore-forming, pathogenic bacterium that forms an enterotoxin in the spore coat. must be ingested in Clostridium perfringens C. perfringens – large quantities while a vegetative cell and then will sporulate in the intestine.
