Genetic control of susceptibility to infection with Plasmodium chabaudi chabaudi AS in inbred mouse strains.

ABSTRACT: To identify genetic effects modulating the blood stage replication of the malarial parasite, we phenotyped a group of 25 inbred mouse strains for susceptibility to Plasmodium chabaudi chabaudi AS infection (peak parasitemia, survival). A broad spectrum of responses was observed, with strains such as C57BL/6J being the most resistant (low parasitemia, 100% survival) and strains such as NZW/LacJ and C3HeB/FeJ being extremely susceptible (very high parasitemia and uniform lethality). A number of strains showed intermediate phenotypes and gender-specific effects, suggestive of rich genetic diversity in response to malaria in inbred strains. An F2 progeny was generated from SM/J (susceptible) and C57BL/6J (resistant) parental strains, and was phenotyped for susceptibility to P. chabaudi chabaud
