Classification of schistosoma haematobium
What is the classification of Schistosoma?
Trematoda is a class within the phylum Platyhelminthes. It includes two groups of parasitic flatworms, known as flukes.
They are internal parasites of molluscs and vertebrates. Most trematodes have a complex life cycle with at least two hosts. The primary host, where the flukes sexually reproduce, is a vertebrate.

What is the common name of Schistosoma Haematobium?
Schistosomiasis (Bilharziasis) is caused by some species of blood trematodes (flukes) in the genus Schistosoma. The three main species infecting humans are Schistosoma haematobium, S.
How do you identify Schistosoma Haematobium?
The definitive diagnosis of urinary schistosomiasis (Schistosoma haematobium) is established by demonstration of S. haematobium eggs in urine. An increased number of eggs is shed in the urine around midday, so an optimum urine specimen for diagnosis should be collected at noon.
What is Schistosoma haematobium infection?
Schistosoma haematobium, a blood fluke which occurs in Africa and the Middle East, infests the small veins of the urinary bladder and produce eggs that are passed in the urine. From: The Nobel Prize Winning Discoveries in Infectious Diseases, 2005.
What are the characteristics of Schistosoma haematobium?
Unlike all other pathologically important trematodes, schistosomes are not hermaphroditic, but have separate sexes. The adult worms are 1–2 cm long with a cylindrical body that features two terminal suckers, a complex tegument, a blind digestive tract, and reproductive organs.
What are the causes of Schistosoma haematobium?
How can I get schistosomiasis? Infection occurs when your skin comes in contact with contaminated freshwater in which certain types of snails that carry schistosomes are living. Freshwater becomes contaminated by Schistosoma eggs when infected people urinate or defecate in the water.
What are the 5 species of schistosomiasis?
The majority of human infections are attributable to 5 species: Schistosoma mansoni, S. japonicum, S. haematobium, S. mekongi and S.
What is Schistosoma haematobium life cycle?
Life cycle: Eggs are eliminated with feces or urine (1). Under optimal conditions, the eggs hatch and release miracidia (2), which swim and penetrate specific snail intermediate hosts (3). The stages in the snail include two generations of sporocysts (4) and the production of cercariae (5).
What is the pathogenesis of Schistosoma haematobium?
Pathogenesis: Schistosomiasis (or bilharziasis) is unusual amongst helminth diseases for two reasons: much of the pathogenesis is due to the eggs (rather than larvae or adults); and most of the pathology is caused by host immune responses (delayed-type hypersensitivity and granulomatous reactions).
What is the common name of Schistosoma japonicum?
Blood fluke
Schistosoma japonicum (Blood fluke) | Taxonomy | UniProt.
Where is Schistosoma haematobium found in the human body?
Adult S. mansoni reside in the venous plexuses of the colon and lower ileum and in the portal system of the liver of their host.
Which Schistosoma is found in urine?
Background. Urinary schistosomiasis is a human disease condition, which is caused by infection of the trematode Schistosoma heamatobium. The parasite is found in the venous plexus draining the urinary bladder of humans [1].
What are the two major forms of schistosomiasis?
The three main types of schistosomes are responsible for the two main forms of the condition: urogenital schistosomiasis and intestinal schistosomiasis. This condition is also known as bilharzia or snail fever.

What is the vector of Schistosoma Haematobium?
mansoni–S. haematobium hybrid parasites are capable of infecting the Bulinus snail vector of the S.
