Botulism Infants can develop botulism after consuming honey contaminated with Clostridium botulinum endospores. citation Infantile botulism shows geographical variation.

C. botulinum produces heat-resistant endospores that are commonly found in soil and are able to survive under adverse conditions.

Certain types of endospores are used to ensure that an autoclaved item has been rendered truly sterile: a small capsule containing the spores is put into the autoclave with the items; after the cycle it is checked to see if anything will grow from it.

Dipicolinic acid is a spore-specific chemical that appears to help in the ability for endospores to maintain dormancy.

Endospores are able to survive at 100 °C for hours, although the longer the number of hours the fewer that will survive.

Thermo-resistant endospores were first hypothesized by Ferdinand Cohn after studying Bacillus subtilis (pictured to the right) growth on cheese after boiling the cheese.

They will germinate within a day or two with the right environmental conditions, and then the vegetative cells, not as hardy as endospores, can be straightforwardly destroyed.

Under stressful environmental conditions, the bacteria can produce oval endospores that are not true 'spores', but to which the bacteria can reduce themselves and remain in a dormant state for very long periods.
