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 ).
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.
intestinal schistosomiasis: Schistosoma mansoni and Schistosoma intercalatum: intestine, liver, spleen, lungs, skin, rarely infects the brain stool Africa, Caribbean, South America, Asia, Middle East – 83 million people skin exposure to water contaminated with infected Biomphalaria freshwater snails urinary blood fluke Schistosoma haematobium
All serum specimens are tested by FAST-ELISA using S. mansoni adult microsomal antigen. A positive reaction (greater than 9 units/μL serum) indicates infection with Schistosoma species. Sensitivity for S. mansoni infection is 99%, 95% for S. haematobium infection, and less than 50% for S. japonicum infection. The specificity of this assay for ...
Orientobilharzia differ from Schistosoma only in the number of testes. The four species in this genus have recently (2012) been moved to the genus Schistosoma on the basis of morphology and molecular studies. [5] The genus name should now be regarded as a junior synonym of Schistosoma.
The 1990–2013 Global Burden of Disease Study estimated 5,500 direct deaths from schistosomiasis, [77] while more than 200,000 people were estimated in 2013 to die annually from causes related to schistosomiasis. [78] Another 20 million have severe consequences from the disease. [79] It is the most deadly of the neglected tropical diseases. [80]
Scabies (also sometimes known as the seven-year itch) is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite Sarcoptes scabiei, variety hominis. The word is from Latin: scabere, lit. 'to scratch'. The most common symptoms are severe itchiness and a pimple -like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person usually ...
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]
