  1. Secondary blood meals were carried out on mice treated with the indicated products and doses on day 7 after mosquito infection. Oocysts were evaluated on day 3 after the secondary blood meal (day 10 post infection). *s1: immature oocysts, before the formation of sporoblasts (fig. 1A); s2: immature oocysts, with visible sporoblasts and budding sporozoites (fig. 1 B1 - B2); s3: mature oocysts containing fully developed sporozoites (fig. 1C). Geometric means, only positive mosquitoes included.
