Explanation:

Ascaris lumbricoides is a parasitic worm that lives in the small intestine of humans. It is the largest parasitic worm in humans, with adult females measuring up to 35 cm in length and males measuring up to 25 cm in length. The worm causes damage to the intestine by feeding on the intestinal contents and by attaching itself to the intestinal wall.

Effects on the Intestine:

Ascaris lumbricoides can cause a variety of gastrointestinal symptoms, including abdominal pain, diarrhea, and vomiting. The worm can also cause intestinal blockages and ruptures, which can be life-threatening. The worm can also cause malnutrition by interfering with the absorption of nutrients from food.

Other Effects:

While Ascaris lumbricoides primarily affects the intestine, it can also migrate to other parts of the body, such as the lungs and liver. In the lungs, the worm can cause coughing, wheezing, and shortness of breath. In the liver, the worm can cause abscesses and other complications.

Treatment:

Ascaris lumbricoides infections can be treated with medications such as albendazole and mebendazole. These medications work by killing the worms and allowing them to be expelled from the body. In severe cases, surgery may be necessary to remove the worms or repair any damage they have caused. To prevent Ascaris lumbricoides infections, it is important to practice good hygiene, such as washing hands regularly and avoiding contact with contaminated soil.
