Strongyloides

 [stron″jĭ-loi´dēz]
a genus of nematode parasites. S. stercora´lis is a species found in the intestines of humans and other mammals in the tropics, and is the most common cause of strongyloidiasis.

Strongyloides

(stron'ji-loy'dēz),
The threadworm, a genus of small nematode parasites (superfamily Rhabditoidea), commonly found in the small intestine of mammals (particularly ruminants), that are characterized by an unusual life cycle that involves one or several generations of free-living adult worms. Human infection is chiefly by S. stercoralis, the small human roundworm, widespread in all tropic regions, or by S. fuelleborni, a parasite of nonhuman primates in African and Asian tropics and of humans in African tropics. The subspecies S. fuelleborni kellyi occurs in New Guinea where it causes widespread infection. Fatal infection in 2-month-old infants, possibly infected by transmammary transmission, produces the condition known locally as swollen belly disease or swollen belly syndrome, which causes grossly distended abdomens, invariably fatal in these infants. Other species include S. papillosus in cattle, sheep, and goats, and S. ransomi in swine.

[105] demonstrated that 96.0% of sera from patients with strongyloidiasis recognized immunodominant antigens of Strongyloides ratti. According to western blots, the sera from infected patients can recognize different molecular antigenic patterns.

Isolate-specific responses have been reported for at least four helminth species (e.g., Strongyloides ratti [Carter 1986]); experiments which fail to find evidence of genotype-specific responses typically involve incomplete experimental designs and analyses of variation within single, highly inbred laboratory lines (Read and Viney 1996).
