What is the tissue organization in an ascaris worm in maturity and in an embryonic stage?
Ascaris is a genus of parasitic nematode worms. One species, A. suum, typically infects pigs, while another, A. lumbricoides, affects human populations, typically in sub-tropical and tropical areas with poor sanitation. A. lumbricoides is the largest intestinal roundworm and is the most common helminth infection of humans worldwide, an infection known as ascariasis. Life cycle Adult A.lumbricoides and A.suum live in the small intestine. A female A.lumbricoides can produce up to 200,000 eggs a day, though the number of eggs produced per female worm is lower when there are large number of worms present in the gut, a phenomenon called density dependent fecundity. When an egg is passed into the environment it develops into a third stage larva in about 10 days, the rate depending on the temperature and relative humidity. This typically takes place on the soil, which is why A.lumbricoides is classified with Trichuris trichiura and the hookworms Necator americanus and Ancylostoma duodenale as
