The clinical symptoms in ill foxes included depression, poor appetite or appetite loss,rough, disorder and dull hair, standing inability, trembling, sunken eyes, decreased skin elasticity, dehydration and loose stools around the anus. When the abdomens of ill foxes were pressed, white or yellow manure flew out from the anuses, and some of the manures contained mucus or blood. The pathological changes included liver enlargement with necrotic lesions, spleen enlargement, lung hemorrhage, kidney enlargement with bleeding spots, thymus hemorrhage and intestinal catarrhal inflammation. The epidemic was finally identified as colibacillosis through clinical symptoms observation, pathological anatomy, biochemical tests and 16 SrRNA amplification.展开更多
