Strongyloidiasis

strongyloidiasis

[‚strän·jə‚lȯi′dī·ə·səs] (medicine) An infestation of humans with one of the roundworms of the genus Strongyloides.

Strongyloidiasis

a helminthiasis of man caused by the intestinal roundworm Strongyloides stercoralis. Those infected with strongyloidiasis excrete the parasite’s larvae with feces. The larvae develop in the soil, and infection occurs when the mature larvae penetrate the skin or enter the body with contaminated food and drink. They are transported in blood vessels and lymphatics to the lungs and then through the airways to the throat. They are subsequently swallowed with saliva and sputum and enter the intestine. The roundworms parasitize the duodenum and less commonly the entire small intestine and the cecum and colon. They sometimes reach the pylorus and biliary and pancreatic ducts. Fever and allergic reactions (hives) develop shortly after infection. The temperature decreases within a few days, and abdominal pain, nausea, and sometimes vomiting and diarrhea occur.

Strongyloidiasis is diagnosed when the parasite’s larvae are found in feces and bile. The disease is treated with thiabendazole or gentian violet. Preventive measures include the observance of the rules of personal hygiene and health regulations in populated areas. Raw vegetables and fruits should not be eaten until they are thoroughly washed and scalded with boiling water.

strongyloidiasis

[stron″jĭ-loi-di´ah-sis] infection with Strongyloides stercoralis. The worms usually inhabit the small intestines, causing intestinal strongyloidiasis with diarrhea and ulceration of the mucosa. At a later stage in their life cycle they may penetrate the skin and be carried to the lungs, causing pulmonary strongyloidiasis with hemorrhaging. Called also strongyloidosis.

stron·gy·loi·di·a·sis

(stron'ji-loy-dī'ă-sis), Infection with soil borne nematodes of the genus Strongyloides, considered to be a parthenogenetic parasitic female. Larvae passed to the soil develop through four larval instars to form free-living adults or develop from first and second free-living stages into infective third-stage strongyliform or filariform larvae, which penetrate the skin or enter the buccal mucosa through drinking water. Infection can occur by larvae of a new generation developed in the soil (indirect cycle), by infective larvae developed without an intervening adult stage (direct cycle), or by larvae that develop directly in the feces within the intestine of the host, penetrate the mucosa, and pass by blood/lung sputum migration back to the intestine (autoreinfection); most serious human infections and nearly all fatalities result from autoreinfection and subsequent disseminated infection, which commonly follow immunosuppression by steroids, adrenocorticotropic, or other immunosuppressive agents. Autoreinfection also may develop in patients with AIDS. Synonym(s): strongyloidosis

strongyloidiasis

A persistent intestinal infection with the small parasitic worm Strongyloides stercoralis , which is common in many parts of the Far East. The infection tends to be permanent by internal breeding and may cause discomfort and distention, diarrhoea, SEPTICAEMIA, MENINGITIS or severe bleeding from the lungs. Treatment is with the drug thiabendazole (tiabendazole) but repeated courses must be given.
