Pasteurellosis in pheasants (fowl cholera) is a contagious bacterial disease that can cause death in all avian species. The cause of disease is Pasteurella spp. In our investigation, pathogenesis, course of disease, mortality rate and effects of specific therapy in parental flock of pheasants are described. Disease occurred in a flock of 1500 pheasant parents at 11th week of age and 14th, 20th, 23rd and 27th week of age, subsequently. During the first two episodes (11th and 14th weeks of age) disease had characteristics of peracute and acute septicaemia with poor clinical signs followed by mortality 20 to 48 hours later. In most cases, death was the only sign of disease. On necropsy, pathological changes indicating septicaemia were present. Signs of chronical disease were also present at 20, 23 and 27 weeks of age. Mortality rate in pheasant flock per episode was 3 to 5%. In all cases Pasteurella multocida was isolated in pure culture from samples of heart and liver. Isolate Pasteurella multocida showed sensitivity to numerous antibiotics including amoxicillin, flumequine and oxitetracycline. According to these results, specific therapy was applied through drinking water and food.
