Parasitic Infection Chain Matching Quiz Solution
Chain A: Man - snail - man & Schistosomiasis (III)
This lifecycle describes Schistosomiasis. Humans release eggs into water, which infect snails. Larvae (cercariae) released from snails then penetrate human skin.
Chain B: Man - cyclops - fish - man & Fish tape worm (I)
This matches the lifecycle of the Fish tapeworm. Humans ingest infected fish. The parasite requires intermediate hosts like copepods (Cyclops) and fish to develop.
Chain C: Man - snail - fish - man & Clonorchis sinesis (IV)
This describes the lifecycle of Clonorchis sinensis (Chinese liver fluke). It involves freshwater snails and fish as intermediate hosts before infecting humans via undercooked fish.
Chain D: Man - snail - crab - man & Paragonimiasis (II)
This lifecycle corresponds to Paragonimiasis (lung fluke). Humans get infected by consuming raw or undercooked crustaceans (like crabs) that have intermediate stages of the parasite from infected snails.
Answer Key: Infection Chains to Diseases
- A - III. Schistosomiasis
- B - I. Fish tape worm
- C - IV. Clonorchis sinesis
- D - II. Paragonimiasis
The correct option is 4, reflecting the matches A-III, B-I, C-IV, and D-II.
