A survey conducted on the causes of duck mortality that about 11 percent of total death of domestic ducks in Bangladesh was due to duck cholera. The disease was experimentally reproduced in young and adult ducks by oral infection with culture of Pasteurella multocida, originally isolated from a case of duck cholera. Mortality following experimental infection varied from 50 to 100 percent depending on the dose of inoculum. Haemorrhage and congestion throughout the visceral organs, focal coagulation necrosis in liver, serofibrinous exudates in lungs and cytoplasmolysis in cardiac fibers and hepatocytes were the principal pathological changes observed in both natural experimental cases of duck cholera.
