Abstract

An outbreak of fowl cholera occurred in a goose flock at Aomori Prefecture in March 1987, showing depression, anorexia, and diarrhea resulting in acute death in 1, 160 (73%) of 1, 582 birds. Necropsy of 8 dead cases revealed multiple necrotic foci in the liver and spleen and multiple petechiae in the heart.Microscopically, multiple necrosis and heterophilic infiltration with bacterial colonies were seen in the heart, lung, kidney and intestine. Pasteurella multocida was isolated in pure culture from the heart, lung, liver, kidney, spleen, ovary and testis as well as ascites and peripheral blood. The isolates were shown to be of Carter's capsular type A, Heddleston's somatic type 1 and Namioka's somatic type O-5, and to be highly pathogenic for geese and chickens.
