Study Notes
Schistosoma: Related Diseases and Characteristics
- The genus Schistosoma is responsible for causing a series of related diseases in humans.
Schistosoma Species and Their Effects
- Schistosoma haematobium primarily affects the urinary tract and causes female genital schistosomiasis.
- S. haematobium infection in humans has a primary effect of causing physical growth and cognitive delays in children.
Habitat and Distribution
- A critical factor contributing to the tropical distribution of schistosomes that infect humans is the presence of freshwater snails.
- Regional increases in schistosomiasis have resulted from changes in human behavior, such as increased migration and travel.
Life Cycle and Habitat
- Schistosome adults remain attached to the mesenteric or pelvic veins for most of their life span.
- S. mansoni adults are found in the mesenteric veins.
Disease and Infection
- Schistosoma infection can cause a disease that results in physical growth and cognitive delays in children.
