Schistosomiasis is spread by contact with fresh water contaminated with parasites. [5] These parasites are released from infected freshwater snails . [ 5 ] The disease is especially common among children in underdeveloped and developing countries because they are more likely to play in contaminated water. [ 5 ]
Schistosoma japonicum is an important parasite and one of the major infectious agents of schistosomiasis.This parasite has a very wide host range, infecting at least 31 species of wild mammals, including nine carnivores, 16 rodents, one primate (human), two insectivores and three artiodactyls and therefore it can be considered a true zoonosis.
Schistosoma is a genus of trematodes, commonly known as blood flukes.They are parasitic flatworms responsible for a highly significant group of infections in humans termed schistosomiasis, which is considered by the World Health Organization to be the second-most socioeconomically devastating parasitic disease (after malaria), infecting millions worldwide.
Schistosomiasis is caused by parasitic worms, picked up in infested waters, which drill through people's skin and lay eggs in their bodies. Parasitic worms may hold key to cutting spread of HIV ...
For S. mansoni and S. japonicum, these are "intestinal" and "hepatic schistosomiasis", associated with formation of granulomas around trapped eggs lodged in the intestinal wall or in the liver, respectively. The hepatic form of the disease is the most important, granulomas here giving rise to fibrosis of the liver and hepatosplenomegaly in ...
Symptoms of all forms of schistosomiasis are caused by the immune system's reaction to the eggs, rather than the adult worms themselves. [5] A few hours to days after cercariae invade the skin, some people experience pruritus and raised papules at the site of penetration. This is called cercarial dermatitis, also known as swimmer's itch.
[5] [6] The eggs of S. bovis are not only larger than those of other schistosomes, but also have thicker spine with an elongated shape in the form a spindle. [7] [8] The eggs are therefore the best and simplest identification key from other species. [9] [10] Sonsino later revised the name as Bilharzia crassa in 1877, and then as Gynaecophorus ...
Dr. Elizabeth Thompson, a dermatologist with Kaiser Permanente in Seattle, notes that while warts can develop at any age, they only affect about 3% to 5% of adults, compared to 10% to 20% of ...
