This video demonstrates an assay for immunizing a mouse model with live attenuated sporozoites. The radiation-attenuated Plasmodium sporozoites are injected into the dorsal side of the mouse's ear. After injections at multiple locations on both ears, the mouse is allowed to recover.

Protocol

All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Materials and Reagents Use female Anopheles stephensi mosquitoes (Sda500 strain) that feed on infected mice 3-5 days after emergence and rear as described previously. Use parasites Plasmodium berghei ANKA clone expressing the Green Fluorescent Protein (GFP) gene under the control of the const…
