The suspected samples were inoculated in to embryonated egg to isolate the suspected virus. Neutralization test was performed using hyperimmune serum of pneumo virus and sera from infected birds. Experimental infection via nostrils was performed, samples from bronchi and lungs were taken for histopathological examination. Results showed that gross lesions were observed after second passage of isolates, two which showed mortality after first passage. Hyperimmune serum and sera from infected birds neutralized the isolates, there was variation among isolates.
