Abstract: The outbreak report concise the key aspect of recent identification and pathological changes associated on natural dead due to Newcastle disease (ND). The outbreak, caused by the avian paramyxovirus, has posed significant challenges to poultry populations and huge economic loss worldwide. This study conducted at the Department of Veterinary Pathology, College of Veterinary Science, A.A.U., Khanapara, Guwahati-22 from an outbreak in broiler flock located in the kamrup district of Assam with a capacity of 400 number of birds which were well maintained under intensive system. Upon internal necropsy examination respiratory organs consistently revealed haemorrhagic tracheitis and congestive pneumonitis in the upper and lower respiratory tracts respectively. Major consistent gross findings were petechial haemorrhages in the proventriculus and caecal tonsils. Histopathological picture of all the visceral organs consistently revealed presence of extensive vascular changes characterized by congestion and haemorrhages and cellular changes characterized by inflammatory cellular infiltration. Following the clinicopathological studies the representative samples from all the suspected cases were subjected to the HA, HI, and molecular detection of complete F gene of NDV by RT-PCR.
