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 warts itch and may hurt, especially if they're on your feet. There are five kinds of warts: Common warts usually appear on the hands. Flat warts usually appear on the face and forehead. Genital warts (condyloma) appear on the genitals, in the pubic area and between the thighs.
