what bacteria does snail have
Nearly 10,000 medical teams are giving out water purification tablets and treating people who have had contact with polluted flood water and so are at risk for getting snail fever, or schistosomiasis. Snail fever, or schistosomiasis, is a parasitic disease of the liver, gastrointestinal tract and bladder. The disease is caused by a specific worm which enters a person's body from infested polluted water. There are three main species of these worms (flukes)-- Schistosoma haematobium, S. japonicum, and S. mansoni -- which cause disease in humans. The larval (young) forms of the parasitic worm live in freshwater snails.
A snail is a common name for a kind of mollusc. The term is used for a gastropod with a coiled shell. Snails and slugs which breath with a kind of lung are members of a group, the Pulmonata, which was a well-known order in traditional taxonomy.
