Parasites can get into the intestines by going through the mouth from uncooked or unwashed food, contaminated water or hands, or by skin contact with larva infected soil; they can also be transferred by the sexual act of anilingus in some cases. When the organisms are swallowed, they move into the intestines, where they can reproduce and cause ...

The estimations of the number of eggs in a gravid female pinworm range from about 11,000 [19] to 16,000. [21] The egg-laying process begins about five weeks after initial ingestion of pinworm eggs by the human host. [19] The gravid female pinworms migrate through the colon towards the rectum at a rate of 12 to 14 cm per hour. [19]
It has been shown to have a worldwide distribution in domestic and/or sylvatic animals. Trichinella is the smallest human nematode parasite, yet it is also the largest of all intracellular parasites. Oral ingestion of cyst- or larvae-contaminated tissue is the usual route of infection, but congenital and mammary transmission can occur in rats. [1]
Pinworms cannot damage the skin, [15] and they do not normally migrate through tissues. [10] However, they may move onto the vulva and into the vagina, from there moving to the external orifice of the uterus, and onwards to the uterine cavity, fallopian tubes, ovaries, and peritoneal cavity. [15] This can cause inflammation of the vulva and vagina.
