BAG1 and cyst: A similar study using a combination of antigens delivered as plasmids coding for two bradyzoite (cyst-specific) fragments (BAG1 and MAG1) in a cocktail DNA vaccine also showed a significant reduction in the number of brain cysts (62% reduction compared with animals vaccinated with empty vector) [66], suggesting that bradyzoite antigens should also be included in a poly-component vaccine to prevent T. gondii infection.
