Both the parasitemia and gametocytemia of mice infected with P. yoelii CSPmut were comparable to those of mice infected with the wild-type parasite (P. yoelii CSPwt), indicating that the CSP pexel I/II mutation had no effect on the development of either the asexual or sexual blood stages of the malaria parasite (Fig. 1b, c). This evidence concerns the gene DNAJC5 and malaria.
