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 roundworm of man, widespread in all tropical regions, or by S. fuelleborni, a parasite of non-human 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. [G. strongylos, round, + eidos, resemblance]
