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.
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.
The life cycle of schistosomes includes two hosts: humans as definitive hosts, where the parasite undergoes sexual reproduction, and snails as intermediate hosts, where a series of asexual reproduction takes place. S. mansoni is transmitted through water, where freshwater snails of the genus Biomphalaria act as intermediate hosts. The larvae ...
Schistosomiasis is known as bilharzia or bilharziosis in many countries, after German physician Theodor Bilharz, who first described the cause of urinary schistosomiasis in 1851. [82] [83] The first physician who described the entire disease cycle was the Brazilian parasitologist Pirajá da Silva in 1908.
In Michigan, for decades, authorities used copper sulfate as a molluscicide to reduce snail host populations and thereby the incidence of swimmer's itch. [citation needed] The results with this agent have been inconclusive, possibly because: Snails become tolerant; Local water chemistry reduces the molluscicide's efficacy; Local currents diffuse it
The parasite can cause canine schistosomiasis, an illness that affects the liver and intestines of dogs, according to Dillman. Read more: It hit 120 degrees in this California town. For the ...
Biomphalaria glabrata is an intermediate snail host for the trematode Schistosoma mansoni, which is one of the main schistosomes that infect humans. [2] This snail is a medically important pest , [ 3 ] because of transferring the disease intestinal schistosomiasis , the most widespread of all types of schistosomiasis .
It can serve as vectors for two serious human diseases: the schistosomiasis blood fluke parasite, and the paragonimus lung fluke parasites. Oncomelania hupensis is the unique intermediate host of Schistosoma japonicum, [7] [13] which causes schistosomiasis endemic in the Far East, and especially in mainland China.
