Abstract
Disseminated visceral coccidiosis (DVC) caused by Eimeria spp. was recognized as a disease entity in captive sandhill cranes (Grus canadensis) and whooping cranes (Grus americana) in the late 1970s. While most avian species of Eimeria inhabit the intestinal tract of its host, the crane eimerians, Eimeria reichenowi and Eimeria gruis, invade and multiply systemically and complete their development in both digestive and respiratory tracts. In DVC, cranes, especially chicks, may succumb to acute infections resulting in hepatitis, bronchopneumonia, myocarditis, splenitis, and enteritis. Cranes may also develop chronic, subclinical infections characterized by granulomatous nodules in various organs and tissues. This paper reviews the pathology and pathogenicity of natural and experimental DVC in sandhill and whooping cranes. Naturally infected birds appeared clinically normal, but progressive weakness, emaciation, greenish diarrhea, and recumbency before death were observed in birds administered doses > or = 10 x 10(3) sporulated oocysts per os. At necropsy, naturally infected birds had nodules in the mucosa of the oral cavity and the esophagus, and in thoracic and abdominal viscera. Experimentally infected birds necropsied less tha...Continue Reading
