Abstract Avian coccidiosis is considered to be one of the most economically important diseases of domestic poultry. Although there has been little effort by the pharmaceutical industry to develop new anticoccidials, the mounting problem of drug resistance of Eimeria species has prompted major research efforts to seek alternative means of control through increased knowledge of parasite biology, host response, and nutritional modulation. As a consequence, important advancements have been made, particularly in definite parasite antigens that have potential use in vaccines defining of Eimeria genome, understanding of the immunology of coccidial infections and the practical applications of live vaccines (Allen and Fetterer, 2002). |
