What is the pathogenesis of Ascaris lumbricoides?

Pathogenesis. The pathogenesis of ascariasis is generally related to organ damage and host reactions to larval migration as well as the number and location of adult worm in the body. Ascaris larvae migrating through the intestinal mucosa, liver and lungs provoke hypersensitivity reaction in the human host.
