Pathology Caused by the Bacterium Edwardsiella tarda in Striped Bass

Abstract

Edwardsiella tarda was isolated from moribund age-0 hatchery-reared striped bass Morone saxatilis for the first time. Pathogenicity was confirmed by contact infection. Characteristic histopathology consisted of epithelial hyperplasia and necrosis associated with the lateral line canals, and abscess formation in the anterior kidney and other internal organs.
