Final answer:
The parasite transmitted through the predator-prey route is Echinococcus granulosus, causing hydatid disease, typically when predators ingest prey containing infectious cysts.
Step-by-step explanation:
The parasite that is transmitted through the predator-prey route is Echinococcus granulosus. This parasitic infection, known as hydatid disease, occurs when a predator, such as a dog, ingests the internal organs of prey animals that contain the infectious cysts of Echinococcus granulosus. Humans can become accidental hosts through direct contact with infected dogs or by ingesting food or water contaminated with the feces of infected dogs.
Ancyclostoma caninum, mentioned in Figure 24.33, is a hookworm that infects animals and can cause cutaneous larva migrans in humans, but it is not primarily transmitted through the predator-prey relationship. It is typically transmitted through skin contact with contaminated soil. Lice, another option given, are ectoparasites that transmit diseases such as typhus, but not through a predator-prey route.
