<p>BALB/c mice were exposed to one, two, four, or five to eight bites by <i>A. stephensi</i> mosquitoes infected with <i>P. yoelii</i> sporozoites. 7 and 14 days following bites, mice were assessed for parasitemia by blood smear. Data from individual mice from five separate experiments (experiments 1β5) are shown. A single strain of <i>A. stephensi</i> (NIJ.SAN01) was used in experiments 1β4 and a second strain (SXK.SAN02) in experiment 5.</p
