Ascarididae

Ascarididae is a family of nematode worms commonly referred to as roundworms. These worms are distributed globally and can be found in various environments, including soil, water, and as parasites in animals. There are several species within this family, with the majority being parasitic and affecting the digestive system of their host.

Ascaris suum, also known as the pig roundworm, is a species that affects pigs but can also be present in humans. As an intestinal parasite, it feeds on the host's nutrients and can cause gastrointestinal symptoms such as diarrhea and weight loss. This species is of medical importance as it can spread through contaminated food and water.

Another notable species within this family is Ascaris lumbricoides, also known as the human roundworm. It is one of the most common parasites infecting humans and can be found in tropical and subtropical regions. Infection occurs when the worm eggs are ingested through contaminated food or water. The parasite lives in the small intestine and can reach lengths of up to 35 centimeters.

Ascarididae are typically white in color and have a long, slender body shape. They have a unique mouth structure, consisting of numerous small teeth used for cutting and eating food. In addition to gastrointestinal symptoms, infection with these worms can also lead to complications such as intestinal obstruction, which occurs when the worm blocks the intestinal tract. Effective treatment options include deworming medication and sanitation measures to prevent re-infection.
