Abstract:
Pasteurellosis is a contagious disease of domestic and wild birds; the course of the disease occurs in acute, septicemic and chronic form. Mortality usually occurs in deep litter floor housed among commercial layers and breeding flock, Outbreak of Pasteurellosis associated with the environment or managemental stress may result in a drop in egg production among breeder and layer flocks causing an economic significance loss for poultry farmers. This study aimed to investigate and characterize the organism associated with birds’ mortality with predominant signs of respiratory distress. The major necropsy findings include air sacculitis, congested lungs, pericarditis, fibrinous perihepatitis, necrotic foci scattered on the surface of liver, flaccid ova and egg yolk peritonitis. Lungs and liver samples were collected and all samples were cultured onto Blood and Mac Conkey agars. Further the pure cultures were subjected for biochemical tests for identification of the organism. The study revealed the significant involvement of M. haemolytica in respiratory infection resulting in mortality in breeder birds.
