Test your knowledge about the Angiostrongylus cantonensis parasite, which remains in larva form in the human body without developing into an adult. Learn about its definitive host, house rats, and how humans are considered its paratenic host. Explore factors like lack of sanitary toilets, use of night soil, and consumption of undercooked freshwater that contribute to parasitic infections.
