stercoralis, autoinfection is believed to be impossible. Since eggs do not hatch within the host as with S. Parasitic females embedded in the submucosa of the small intestine and produce eggs via parthenogenesis (parasitic males do not exist). In the small intestine, larvae molt twice and become adult female worms. These larvae migrate via the bloodstream to the lungs, where they are eventually coughed up and swallowed, or reach the intestine via migration through connective tissue or abdominal viscera. The filariform larvae penetrate the human host skin to initiate the parasitic cycle. The free-living adults mate and produce eggs, from which more rhabditiform larvae hatch and eventually become infective filariform larvae. Eggs hatch shortly after passage into the environment, releasing rhabditiform larvae, that develop to either infective filariform larvae (direct development) or free-living adult males and females. stercoralis, with the important distinction that eggs (rather than larvae) are passed in the stool. Strongyloides fuelleborni follows the same life cycle as S. The significance of autoinfection in Strongyloides is that untreated cases can result in persistent infection, even after many decades of residence in a non-endemic area, and may contribute to the development of hyperinfection syndrome. Once the filariform larvae reinfect the host, they are carried to the lungs, pharynx and small intestine as described above, or disseminate throughout the body. Rhabditiform larvae in the gut become infective filariform larvae that can penetrate either the intestinal mucosa or the skin of the perianal area, resulting in autoinfection. The rhabditiform larvae can either be passed in the stool (see “Free-living cycle” above), or can cause autoinfection. The females live embedded in the submucosa of the small intestine and produce eggs via parthenogenesis (parasitic males do not exist), which yield rhabditiform larvae. In the small intestine, the larvae molt twice and become adult female worms. through abdominal viscera or connective tissue). However, 元 larvae appear capable of migrating to the intestine via alternate routes (e.g. It has been thought that the 元 larvae migrate via the bloodstream and lymphatics to the lungs, where they are eventually coughed up and swallowed. Parasitic cycle: Filariform larvae in contaminated soil penetrate human skin when skin contacts soil, and migrate to the small intestine. This second generation of filariform larvae cannot mature into free-living adults and must find a new host to continue the life cycle. The filariform larvae penetrate the human host skin to initiate the parasitic cycle (see below). In the free-living cycle: Rhabditiform larvae are passed in the stool of an infected definitive host, develop into either infective filariform larvae (direct development) or free-living adult males and females that mate and produce eggs, from which rhabditiform larvae hatch and eventually become infective filariform (元) slarvae.
