Trachea: petechiae.
Morphologic diagnosis:
Trachea: Mild multifocal petechia
Clinical description:
Velogenic viscerotropic Newcastle disease. This image is from an acute outbreak, where many birds were suddenly found dead. On post-mortem exam, no severe lesions were found due to the rapid onset of the infection. Only mild hemorrhagic lesions in the mucosa of the trachea were observed (as seen here). In flocks unvaccinated for NDV, massive deaths within the flock may occur quickly, without any prior signs of illness and few post-mortem lesions.
Pathologic description:
Pinpoint red foci are scattered along the mucosal surfaces. These foci are particularly dense in areas running parallel to the cartilaginous rings.
