Botulism is a rare but serious paralytic illness caused by a nerve toxin produced by the bacterium Clostridium botulinum (klos-trih-dee-um bot-u-li-num). Human botulism is mainly caused by four of the seven recognized types of Clostridium botulinum bacteria: types A, E, rarely F and possibly G. The recorded history of botulism began in 1735, when the disease was first associated with the consumption of sausage.
Warts occur in a variety of shapes and sizes. A wart may appear as a bump with a rough surface, or it may be flat and smooth. Tiny blood vessels (capillaries) grow into the core of the wart to supply it with blood.

Some are more likely to affect particular areas of the body. For example, verrucas are warts that usually develop on the soles of the feet.arts are small lumps that often develop on the skin of the hands and feet.
