- The causative organism of roundworm is a type of parasitic worm known as nematodes. These worms belong to the phylum Nematoda and can infect humans and animals.
- The life cycle of a roundworm typically begins when eggs are ingested by a host, either through contaminated food or water. Once inside the host's digestive system, the eggs hatch into larvae, which then migrate to various tissues and organs in the body. The larvae mature into adult worms, which reproduce and release eggs into the host's feces, completing the cycle.
- The pathophysiology of roundworms involves the worms causing damage to the host's tissues and organs as they migrate and feed. This can lead to a variety of symptoms depending on the location and severity of the infection. Common symptoms of roundworm infections include abdominal pain, diarrhea, weight loss, fatigue, and malnutrition. In severe cases, roundworm infections can lead to complications such as intestinal blockages, organ damage, and even death. Treatment typically involves antiparasitic medications to kill the worms and alleviate symptoms.

Causative Organism of Roundworm
- Ascaris lumbricoides
Life Cycle of a Roundworm
1. Adult worms in the intestine: Adults live in the small intestine, where they mate and lay eggs.
2. Eggs in the soil: Eggs are passed in the stool and contaminate soil.
3. Infective larvae: After 2-3 weeks in soil, eggs develop into infective larvae.
4. Ingestion of eggs: When contaminated soil or food is ingested, larvae hatch in the small intestine.
5. Migration through the body: Larvae penetrate the intestinal wall and enter the bloodstream. They travel to the lungs, then back up the respiratory tract to the esophagus, and finally to the small intestine again.
6. Maturation in the intestine: In the small intestine, larvae develop into adult worms and repeat the cycle.
Pathophysiology of Roundworms
- Mechanical obstruction: Heavy infestations can cause intestinal obstruction, leading to abdominal pain, vomiting, and constipation.
- Malnutrition: Roundworms compete with the host for nutrients, leading to anemia, protein deficiency, and stunted growth.
- Allergic reactions: Roundworm eggs and larvae can trigger allergic reactions, causing itching, rash, and respiratory symptoms.
- Hepatic dysfunction: Adult worms can invade the liver, causing inflammation and damage.
- Pulmonary infiltration: Migrating larvae can cause inflammation in the lungs, leading to coughing, wheezing, and fever (known as Löffler's syndrome).
- Eosinophilia: Roundworm infections often cause elevated eosinophil levels in the blood.
