Adult Schistosoma haematobium has male and female, which are permanently paired (a condition called in copula) as what looks like an individual. The male forms the flatworm part, measuring 10–18 mm in length and 1 mm in width. It bears oral and ventral suckers towards its anterior end.
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.
Infected Schistosoma individuals release eggs into water via their fecal material or urine. A collection of stool samples under a microscope will show the eggs of S. intercalatum, S. mansori, and S. japonicum. Looking at a urine sample under a microscope would reveal the eggs of S. haematobium and rarely, the eggs of S. mansori. [38]
In 1858 Weinland proposed the name Schistosoma (Greek: 'split body') after the male worms' morphology. Despite Bilharzia having precedence the genus name Schistosoma was officially adopted by the International Commission on Zoological Nomenclature. In 1898 all the then known species were placed in a subfamily by Stiles and Hassel.
[The female] was completely enclosed in the groove-shaped half canal of the male posterior, similar to a sword in a scabbard. [23] Anterior portion of a blood fluke (Schistosoma). The two mouth-like structures are the oral and ventral suckers of a male. The female is like a roundworm protruding below the ventral sucker of male.
Congress required all federal agencies to submit annual financial reports in 1990. The Pentagon finally got around to complying in 2018, and it still hasn't passed an audit.
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). Clinical symptoms are caused by the eggs.
