Abstract |
Humanized mice with a chimeric liver are a promising tool to evaluate the "in vivo" efficacy of novel compounds or vaccine-induced antibodies directed against the pre-erythrocytic stages of Plasmodium falciparum. The absence of human red blood cells in these humanized mice precludes the transition from liver to blood stage. The qPCR-based method described below allows for a sensitive and reliable quantification of parasite DNA in the chimeric liver following a challenge via infected mosquito bite or intravenous injection of sporozoites. With this method approximately 25 % of the total chimeric liver is examined and a single infected hepatocyte can be detected in the analyzed tissue. The use of appropriate species-specific probes can also allow for the detection of other Plasmodium species in vivo. |
