Study Notes
Strongyloides stercoralis Distribution
- Strongyloides stercoralis is more frequently found in tropical and subtropical regions.
Initiation of Parasitic Cycle
- Filariform larvae penetrate the human skin, usually through contact with contaminated soil or feces, to initiate the parasitic cycle in humans.
Life Cycles
- Strongyloides stercoralis has two types of life cycles: free-living cycle and parasitic cycle.
- The free-living cycle occurs in the soil, while the parasitic cycle occurs in the human host.
Adult Female Worms
- Adult female worms of Strongyloides stercoralis reside in the intestinal mucosa of the human body, specifically in the duodenum and jejunum.
Rhabditiform Larvae Development
- In the free-living cycle, rhabditiform larvae of Strongyloides stercoralis develop into infective filariform larvae.
