types of the host Definitive/final host is the host in which the parasite become sexually mature(where the adult worm harbor or undergoing sexual reproduction) Intermediate host is the host in which the parasite undergoes larval development but does not reach sexual maturity, parasites often can undergo asexual reproduction in this type of host. Typically, the intermediate host must be eaten to transmit the parasite to the next host.—types of the host ◼ Definitive/final host is the host in which the parasite become sexually mature (where the adult worm harbor or undergoing sexual reproduction) ◼ Intermediate host is the host in which the parasite undergoes larval development but does not reach sexual maturity, parasites often can undergo asexual reproduction in this type of host.
