An antigen from Eimeria tenella merozoites for the indirect fluorescence antibody test

: The suitability of the antigen prepared from second generation merozoites of Eimeria tenella for the IFAT was confirmed. In comparison with other two antigens used until now in routine work, i. e., that prepared from histological sections of infected organs or that from in vitro released sporozoites, the merozoite antigen has the advantage of easy preparation in large quantities.
