Feedback:
The chills and fever associated with an acute malarial attack are caused by the rupture of red blood cells containing merozoites. These symptoms are related to the pyrogenic effects of the protozoa and the toxic effects of the red blood cell components on the system. The formation of sporozoites occurs in the stomach of the mosquito when the male and female gametocytes mate and produce a zygote. Invasion of the tsetse fly causes trypanosomiasis, which affects the central nervous system. The release of amastigotes occurs in leishmaniasis, which is caused by the sand fly and is part of a cyclic pattern that causes serious skin lesions.
