Transmission electron micrograph of Clostridium botulinum bacteria,the cause of botulism food poisoning. The bacterium seen in longitudinal section at right is in the process of spore formation; the spore is the pale,circular region at top. Spores enable C. botulinum to survive in unfavourable conditions. The bacterium is found in soil,untreated water and badly preserved canned foods,notably meat & fish. It produces a potent exotoxin which attacks the central nervous system; death can result from heart and lung failure due to malfunctions in the cardiac and respiratory centres of the brain.
