Ascaris lumbricoides

One of several species of Ascaris / From Wikipedia, the free encyclopedia

Ascaris lumbricoides is the "large roundworm" of humans, growing to a length of up to 35 cm (14 in).[1] It is one of several species of Ascaris. An ascarid nematode of the phylum Nematoda, it is the most common parasitic worm in humans. This organism is responsible for the disease ascariasis, a type of helminthiasis and one of the group of neglected tropical diseases. An estimated one-sixth of the human population is at some point infected by A. lumbricoides or another roundworm.[2] Ascariasis is prevalent worldwide, especially in tropical and subtropical countries.[3]
