What is the scientific name of the causative agent for pinworms?

The causative agent for pinworms is Enterobius vermicularis. This nematode is specifically known for causing intestinal infections, particularly in young children, where it leads to symptoms such as anal itching and discomfort. The lifecycle of Enterobius vermicularis involves eggs that are laid around the anus, which can be easily spread to others and contribute to its commonality in households and child care settings.

In contrast, Ascaris lumbricoides is known for causing ascariasis, a different type of intestinal parasitic infection characterized by larger roundworms. Toxocara canis, associated with dogs, causes visceral larval migrans and is not related to human pinworm infections. Necator americanus is a hookworm that leads to anemia and other gastrointestinal issues in humans. Each of these organisms has distinct clinical manifestations and biological characteristics, making Enterobius vermicularis the correct identification for pinworms.
