As the most common nematode parasite of humans in North America and Europe, pinworms Enterobius vermicularis infect more than million people worldwide.
Living in the large intestine, pinworm infestations may be asymptomatic or result in mild irritations of the gastrointestinal tract. Mature female pinworms are about twice as long as the 5-millimeter-long males, which live only until copulation occurs.
When she is ready to lay her 10, plus eggs, the female enterobkus crawls out of the host’s anus, deposits the eggs on the perianal skin, and then dies.
At the average human body temperature of The eggs are ingested by another human host and enteroius in the small intestine. In about a month, the parasitic nematodes reach maturity and reproduce sexually, reinitiating the life cycle. A common symptom of a pinworm infestation is perianal itching associated with the nocturnal egg-laying habits of E.
