loma. The infection granuloma decreases in size due to the recruitment of suppressor T-cell. The anti bodies have no effect on the granuloma. Eggs and granulomas release factors that induce fibroblast proliferation in vitro. The early cellular response induced by granulomas is followed by fibrosis in vivo, however liver fibroses in humans probably involves more then simple tusion of fibro tic granulomas. The disease is held in two hosts. In the adult stage it is in mammals usually humans. It spends its immature stage in certain snails. Eggs discharge from the host and hatch in to larva form in fresh water the larvae, miracidia invade the snail that acts as an intermediate hostSchistosomiasis is transmitted through swimming in contaminated water. The water is mainly found in the eastern country. Another way that it is transmitted is through snails. They get it through little things called cercariae. You can also get it through having contact with an infected person. The first person to describe the disease was a German physician named Theodore Bilharz, in 1851. The disease is found in Egypt, Brazil, Venezuela, the Caribbean islands, Africa, Far East, Philippines. In North America it is found in Michigan, Wisconsin, Canada, especially Manitoba. Misc.: two hundred million people suffer world wide from Schistosomiasis. It is often misdiagnosed as Typhoid Fever. It is also found in mammals such as cattle and water buffalo. Treatment: Chemotherapy is on treatment method. Most infected people benefit from the treatments. To of the best drugs for treatment are Praziquantel and Oxamniquine. The side effects are mild and transient, some of then are as followed:*Abdominal pain*Lethargy*Diarrhea*Fever*Dizziness*Tiredness*Nausea*VomitingPraziquantel costs about 30-40 cents. Know that you know about all the causative agents, symptoms, hosts, methods of transmission and the history of Schistosomiasis, maybe you h...
