Ascaris juvenile causes

• A. Appendicitis
• B. Pneumonia
• C. Hepatitis and brain damage
• D. All of the above

Answer 1

The correct option is B Pneumonia

Adult worms small intestine live in the lumen of the small intestine. A female may produce approximately 200,000 eggs per day, which are passed with the feces. Unfertilized eggs may be ingested but are not infective. Fertile eggs embryonate and become infective after 18 days to several weeks, depending on the environmental conditions (optimum: moist, warm, shaded soil). After infective eggs are swallowed, the larvae hatch, invade the intestinal mucosa and are carried via the portal, then systemic circulation to the lungs. The larvae mature further in the lungs (10 to 14 days), penetrate the alveolar walls, ascend the bronchial tree to the throat, and are swallowed. Worms(juvenile stage) that travel into the bile ducts can cause blockage and infection of the liver, pancreas, or both. When the roundworm’s larvae migrate through the lungs, they can cause allergic lung inflammation (pneumonitis) along with fever, cough, and wheezing.

So, the correct answer is 'Pneumonia'.
