The structure of a major surface antigen SAG19 from Eimeria tenella unifies the Eimeria SAG family

Abstract

Ramly, Dix et al. report the first high-resolution crystal structure of a major surface antigen (SAG) from Eimeria tenella, a parasite that infects poultry. This structure represents the prototype for many Eimeria SAGs and provides insight into the function of these surface proteins.
