Infection rates after exposure to the bite of one to eight P. yoelii-infected mosquitoes.

BALB/c mice were exposed to one, two, four, or five to eight bites by A. stephensi mosquitoes infected with P. yoelii sporozoites. 7 and 14 days following bites, mice were assessed for parasitemia by blood smear. Data from individual mice from five separate experiments (experiments 1–5) are shown. A single strain of A. stephensi (NIJ.SAN01) was used in experiments 1–4 and a second strain (SXK.SAN02) in experiment 5.
