PQS - Ornithobacterium rhinotracheale and anatipesteifer disease✅ Flashcards
The clinical signs of anatipestifer disease are more severe in hens than in ducks.
F
Mainly seen in ducks
Ataxia and spasms are common clinical signs of anatipestifer disease.
T
Anatipestifer disease is a zoonosis
F
Sinusitis is a frequent clinical sign of ornithobacteriosis
T
Nervous signs are frequently seen in the case of ornithobacteriosis
F
The agent of anatipestifer disease causes septicaemia.
T
The agent of anatipestifer disease is an obligate pathogenic bacterium
F
facultative pathogenic bacterium
Clinical signs of anatipestifer disease are limited to the respiratory tract.
F
Anatipestifer disease can be prevented by inactivated and attenuated vaccines.
T
Ornithobacterium rhinotracheale can cause disease in chicken and turkey
T
Wide host range
Production of large amount of mucous in the upper respiratory tract is common in
ornithobacteriosis
T
The agent of ornithobacteriosis colonises the upper respiratory tract
T
Nasal discharge and conjunctivitis are clinical signs of anatipestifer disease.
T
The endothelium is damaged in anatipestifer disease
T
primary target = small blood vessels, which increases the permeability
germinative transmission is important in the case of anatipestifer disease
F
germinative infection has no importance
Generally laying flocks are vaccinated in order to prevent ornithobacteriosis
F
Overcrowding can predispose animals to ornithobacteriosis
T
Deformation of the eggshell can be seen in the case of ornithobacteriosis
