Abstract (en)

[origin: WO9503813A1] Novel stage-specific and intracellular protective Eimeria antigens are disclosed. The antigens are identifiable using antibody preparations produced locally, at the site of parasitic infection. The antibodies and antigens are useful as diagnostic reagents to detect coccidiosis as well as to determine the state of immunity of a particular avian subject. The antibodies and antigens are also useful in vaccine compositions to provide protection against Eimeria infection.
