SLIDE 2
Birds appear depressed and lethargic with ruffled feathers
SLIDE 3
Newcastle disease. Facial edema and conjunctivitis with ocular exsudate.
SLIDE 4
Hemorrhage of the lymphoid tissue of the lower eyelid.
SLIDE 5
Facial edema associated with periocular swelling.
SLIDE 6
Clinical aspects of encephalitis found in Newcastle disease. Nervous disorders result in torticollis.
SLIDE 7 Diarrhea, pasting of feces
SLIDE 8
Newcastle disease (velogenic). Hemorrhagic tracheitis.
SLIDE 9
Soft-shelled, roughened and deformed eggs.
SLIDE 10 Velogenic viscerotropic Newcastle disease. Many of the eggs shown here are rough, misshapen, and thin-shelled. These findings are
- ften present in viscerotropic velogenic Newcastle and infectious
bronchitis infections, where fever stalls the normal movement of the egg through the oviduct, causing deformed and defective shells.
SLIDE 11 Ovaries of infected hens are often shrunken. The stigmata may be
- hemorrhagic. The stigmata appears as a constriction, cutting down into
the ovum.
SLIDE 12
Some ovaries have ova with areas of hemorrhage and necrosis.
SLIDE 13
Enlarged, mottled spleen with pinpoint areas of necrosis
SLIDE 14
A variable degree of hemorrhage in cecal tonsils is frequently observed in Newcastle disease. This lesion can be seen without opening the ceca.
SLIDE 15
Hemorrhage in the proventriculus is a frequent lesion of velogenic strains of ND. But it may be absent. Hemorrhagic lesions can also be observed in the gizzard
SLIDE 16 Within this segment of the duodenum there is a discrete, purple, slightly swollen focus within the wall. The lesion is being viewed through the intact
- serosa. The discrete nature of the lesion suggests that it is affecting one of
the lymphoid aggregates present in the intestinal submucosa.
