Schistosoma and Plasmodium Species Both Require

Question

Schistosoma and Plasmodium species both require
A) direct sexual contact for transmission.
B) immunocompromised hosts.
C) transmission by insect vectors.
D) two hosts to complete their life cycle and reproduce.

Accepted Answer

Both Schistosoma and Plasmodium species require two hosts in order to complete their life cycle and reproduce. Schistosoma species require a snail as an intermediate host and a mammal (often human) as a definitive host, while Plasmodium species require a mosquito as an intermediate host and a mammal (often human) as a definitive host. This two-host requirement is a key factor in the epidemiology and control of these parasites.
