Viral tracheitis in goslings in Saskatchewan.

Up to 12% mortality occurred in goslings between 4 and 11 days of age in two sequential hatches from a single breeder flock. Respiratory signs were noted before the birds died. The most consistent necropsy finding was a white opaque plug of fibrin and cellular debris in the trachea. The tracheal epithelium was hyperplastic and metaplastic with intranuclear inclusion bodies present in superficial cells. An adenovirus was isolated in both chicken and goose embryo liver cells.

A simple vascular perfusion technique for use in waterfowl.

A simple vascular perfusion technique is described for fixation of avian tissues for study at the light-microscope level. The technique relies on gravity feed of perfusate and gives reliable fixation of the nervous system, liver, kidney, and cardiac and skeletal musculature.

Pathology of experimental avian cholera in mallard ducks.

Mallard ducks (Anus platyrynchos) challenged with two isolates of Pasteurella multocida developed either acute or chronic lesions, depending on the isolate of P. multocida and the inoculation dose. Ducks that died acutely of avian cholera had lesions of a hemorrhagic septicemia with widespread vascular damage and focal necrosis in liver, spleen and other organs. Ducks that survived challenge developed chronic lesions in a variety of organs, including brain, lung, air sacs, joints, and eyes. Some surviving ducks sequestered bacteria within these loalized lesions and may be potential "carrier" birds. The possible pathogenesis of P. multocida infection in ducks is discussed.
