ascaris lumbricoides
Infection with Ascaris lumbricoides is acquired fecal-orally by ingestion of Ascaris eggs in contaminated food. Once the eggs hatch, the larvae burrow through the intestinal wall and migrate to the lungs, causing pulmonary symptoms (e.g., dry cough, blood-tinged sputum, wheezing).
