Sick birds appear lethargic, and when captured may die within minutes. Lesions Hemorrhages may be seen on the heart, liver, gizzard, and intestines. The liver may appear darkened or copper in color, and may be swollen and rupture when handled. These lesions are indicative of an acute disease process and are not unique to avian cholera infection. The upper digestive tract may contain recently ingested food, while lower digestive tract may contain a thick yellowish viscous fluid that contains large numbers of P. multocida bacteria.
Avian cholera is highly contagious and can spread rapidly.
Prompt action is needed to prevent and minimize the spread of the disease. Careful carcass collection and disposal helps reduce the amount of bacteria in the environment. Recommendations are site specific. Contact the National Wildlife Health Center for more information. Public Health Significance Humans are not at a high risk for infection with the bacterial strain causing avian cholera.
