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 was first reported in the Mekong River's Lower Basin region in 1957, from Laotian island of Khong to Cambodian province of Kratié, specifically. [2] It was believed that the cause of these cases was Schistosoma japonicum until 1978, when Neotricula aperta was discovered and it was determined that the Schistosome was a unique species, Schistosoma mekongi.

In water, the eggs hatch to become miracidia, which penetrate the freshwater snail intermediate host. [5] S. intercalatum has two major strains, each with its own preferred bulinid host. The Zaire strain will use Bulinus africanus, while the Lower Guinea strain will use the extremely common B. forskalii as its intermediate host. [6]
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.
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 .
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 ...
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.
Biomphalaria straminea is a species of air-breathing freshwater snail, an aquatic pulmonate gastropod mollusk in the family Planorbidae, the ram's horn snails.. This snail is a medically important pest, [1] because an intermediate host for the parasite Schistosoma mansoni and a vector of schistosomiasis.
