Schistosoma mansoni is a water-borne parasite of humans, and belongs to the group of blood flukes (Schistosoma). The adult lives in the blood vessels ( mesenteric veins ) near the human intestine. It causes intestinal schistosomiasis (similar to S. japonicum , S. mekongi , S. guineensis , and S. intercalatum ).
Stool examination should be performed when infection with S. mansoni or S. japonicum is suspected, and urine examination should be performed if S. haematobium is suspected. Eggs can be present in the stool in infections with all Schistosoma species. The examination can be performed on a simple smear (1 to 2 mg of fecal material).
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 .
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), with hundreds of millions infected worldwide.
The roundworm, Dracunculus has a complex mode of transmission: it is acquired from drinking infested water or eating frogs and fish that contain (had eaten) infected crustaceans ; and can also be transmitted from infected pets (cats and dogs). [30] Roundworms such as Brugia, Wuchereria and Onchocerca are directly transmitted by mosquitoes.
Sparganosis is a parasitic infection caused by the plerocercoid larvae of the genus Spirometra including S. mansoni, S. ranarum, S. mansonoides and S. erinacei. [1] [2] It was first described by Patrick Manson in 1882, [3] and the first human case was reported by Charles Wardell Stiles from Florida in 1908. [4]
Schistosoma haematobium (urinary blood fluke) is a species of digenetic trematode, belonging to a group (genus) of blood flukes (Schistosoma). It is found in Africa and the Middle East. It is the major agent of schistosomiasis, the most prevalent parasitic infection in humans. [1]
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 .
