Ascaris lumbricoides
Ascaris lumbricoides
Ascaris lumbricoides (pronunciation: /æsˈkærɪs ˌlʌmbrɪˈkɔɪdiːz/) is a species of parasite that is the most common cause of human ascariasis. The name is derived from the Latin Ascaris, meaning "intestinal worm", and lumbricoides, meaning "earthworm-like".
Description
Ascaris lumbricoides is a large roundworm, or nematode, that can grow up to 35 cm in length. The adult worms live in the small intestine of humans and other mammals. They are typically white or yellowish in color.
Life Cycle
The life cycle of Ascaris lumbricoides begins when eggs are ingested from contaminated soil. The eggs hatch in the intestine, and the larvae migrate through the bloodstream to the lungs. After maturing, the larvae return to the intestine, where they grow into adult worms.
Symptoms and Treatment
Infection with Ascaris lumbricoides can cause a variety of symptoms, including abdominal pain, diarrhea, and malnutrition. In severe cases, the worms can cause a blockage in the intestine. Treatment typically involves antiparasitic medications such as albendazole or mebendazole.
Prevention
Prevention of Ascaris lumbricoides infection involves proper sanitation and hygiene practices, including washing hands before eating and avoiding contact with contaminated soil.
