FIG. 4.

Parasite RNA loads in the livers of wild-type and MBL-A^−/− mice infected with P. yoelii sporozoites. Mice were inoculated with highly infective P. yoelii sporozoites, and the levels of parasite rRNA present in their livers were determined 42 h after infection, as described in Materials and Methods. The results are expressed as the mean values ± standard deviations for six mice.
