S. japonicum is the most pathogenic of the schistosoma species because it produces up to 3,000 eggs per day, ten times greater than that of S. mansoni. [5] As a chronic disease, S. japonicum can lead to Katayama fever, liver fibrosis, liver cirrhosis, liver portal hypertension, splenomegaly, and ascites. Some eggs may pass the liver and enter ...
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 ).
Fibrotic hepatic schistosomiasis caused by S. mansoni usually develops in around 5–15 years, however, this can take less time for S. japonicum. [19] Symptoms may include: Esophageal varices (can cause life-threatening esophageal variceal bleed) [31] Ascites (end-stage) [31] Caput medusae [19] Enlarged spleen and liver [19] Complications may ...
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.
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]

In humans, accidental infection can occur through the consumption of contaminated water or food. The symptoms of Eurytrematosis in ruminants include weight loss, diarrhea and anemia. Infected animals may also exhibit signs of liver damage such as jaundice and ascites. In humans, symptoms can include abdominal pain, diarrhea and weight loss.
Schistosoma - mammals including humans; Trichobilharzia - birds (mainly waterfowl) 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]
