[5] Since 2000, Flubendazole-treated grit has increasingly been laid out on a landscape-scale across many UK grouse-shooting moors by gamekeepers in an attempt to reduce the impact on bird numbers from strongyle worm. Evidence of high worm burden is required before a veterinarian can dispense and sell the product, known as 'medicated grit'. [6]
The period of time from swallowing eggs to the appearance of new eggs around the anus is 4 to 8 weeks. [2] Some people who are infected do not have symptoms. [1] The disease is spread between people by pinworm eggs. [1] The eggs initially occur around the anus and can survive for up to three weeks in the environment. [1]
Enterobius yagoi Sutton, 1979 [3] The pinworm ( species Enterobius vermicularis ), also known as threadworm (in the United Kingdom, Australia and New Zealand) or seatworm , is a parasitic worm . It is a nematode (roundworm) and a common intestinal parasite or helminth , especially in humans. [ 7 ]

English: Enterobiasis Enterobius vermicularis Life cycle of Enterobius vermicularis Eggs are deposited on perianal folds. Self-infection occurs by transferring infective eggs to the mouth with hands that have scratched the perianal area. Person-to-person transmission can also occur through handling of contaminated clothes or bed linens.
Whole blood with microfilaria worm, giemsa stain. L. loa worms have a simple structure consisting of a head (which lacks lips), a body, and a blunt tail. The outer body of the worm is composed of a cuticle with three main layers made up of collagen and other compounds which aid in protecting the nematodes while they are inside the digestive system of their host.
Worms commonly live for about one year, [5] during which time females can lay up to 20,000 eggs per day. Recent studies using genome-wide scanning revealed that two quantitative trait loci on chromosome 9 and chromosome 18 may be responsible for a genetic predisposition or susceptibility to infection of T. trichiura by some individuals.

But the predominant structure of the C. elegans alae contain the ZP domain proteins (CUT-1, CUT-3, CUT-5). The ZP domain had been termed ‘the sequence in search of a function’ and has been given the functional role of matrix assembly and also putatively, functions in pheromone and olfactory signal transduction .
