immune responses against sexual stages of plasmodium vivax during human malarial infections in sri lanka. | during natural infections of p. vivax malaria a variety of immune responses to the infection affect infectivity of the parasites to mosquitoes. sexual stage antigens present in the blood stage parasites induce antibodies which may either enhance or suppress the infectivity of the sexual parasites to mosquitoes. subsequent infections of p. vivax do not, unless occurring within less than 4 months, boost this response indicating a very short immune memory for the relevant antigens. blood infection ... | 1991 | 1688139 |
