ABSTRACT
Coccidiosis can affect any type of bird-raising production in all kind of facilities. This disease can be slight and pass unnoticed, result of the ingestion of few oocists, or be serious as a result of the ingestion of millions of oocists. The Eimeria protozoa genus, that produces this disease, multiplies in the intestine causing damage in that area; and develops different pathogenesis depending on the species of Eimeria that is affecting. Within each guest diverse species of variable pathogenicity exist; however, they are unique for a specifi c host. The only limit of these protozoa infections is the distribution of its guests. Nevertheless, the disease appears under singular conditions of high density population, which favors the presence of potentially pathogenic populations of the parasite. The following report documents the clinical fi ndings in chickens (broilers) sent to the Diagnostic Laboratory of the college of Veterinary Medicine and Animal Husbandry of the Autonomous University of Tamaulipas, which, besides showing common alimentary tract lesions, there were also injuries in liver where the protozoa was identifi ed. It has to be considered that the disease can be more serious than it already is, and that the Eimeria that normally is located in intestine, is migrating to other organs, increasing the severity of the disease and causing economic loss to bird-raising producers.REFERENCES
