Fibrotic hepatic schistosomiasis caused by S. mansoni usually develops in around 5–15 years, while it 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 include:
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 ).
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.
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
Symptoms include “sensitivity to light, dizziness, pain behind the eyes, nausea, vomiting, and rash,” the CDC says, while more serious disease includes meningitis, encephalitis, and bleeding.
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]
Parasitic worms, also known as helminths, [1] are a polyphyletic group of large macroparasites; adults can generally be seen with the naked eye. Many are intestinal worms that are soil-transmitted and infect the gastrointestinal tract. Other parasitic worms such as schistosomes reside in blood vessels.
