The estimations of the number of eggs in a gravid female pinworm ranges from about 11,000 [12] to 16,000. [18] The egg-laying process begins approximately five weeks after initial ingestion of pinworm eggs by the human host. [12] The gravid female pinworms migrate through the colon towards the rectum at a rate of 12 to 14 centimetres per hour. [12]

These eggs have a strong shell that protects them against a range of environmental conditions. The eggs can therefore survive in the environment for many months or years. Many of the worms referred to as helminths are intestinal parasites. An infection by a helminth is known as helminthiasis, helminth infection, or intestinal worm infection ...

It is noteworthy to study the patterns of autoinfection in this parasite in relation to the patterns of autoinfection in Gyrinicola batrachiensis to serve as a comparison for differences in similarities in the production of two different kinds of eggs in parasites. Usually, members of the order Oxyurida are transmitted by thick-shelled eggs ...
Strongyloides stercoralis is a human pathogenic parasitic roundworm causing the disease strongyloidiasis.Its common name in the US is threadworm.In the UK and Australia, however, the term threadworm can also refer to nematodes of the genus Enterobius, otherwise known as pinworms.
Parasite eggs passed in the bird's feces are subsequently collected by foraging C. atratus and are fed to their larvae, thus completing the lifecycle of M. neotropicum. [56] Similarly, multiple varieties of nematodes have been found in the abdominal cavities of the primitively social sweat bee, Lasioglossum zephyrus. Inside the female body, the ...
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
