Europe is free from atrophic rhinitis
F
Dermonecrotoxin producing Pasteurella multocida can cause irreversible lesions in the nose of pigs
T
The dermonecrotoxin of Pasteurella multocida damages the osteoclast cells
F
Dermonecrotoxin producing Pasteurella multocida can cause irreversible lesions in the nose of pigs
T
Toxoid vaccines are used for the prevention of atrophic rhinitis
T
The block of the lachrymal channel is a clinical sign of atrophic rhinitis
T
The turbinate bones can absorbed in the case of atrophic rhinitis
T
Overcrowding can predispose pigs to atrophic rhinitis
T
The maxilla can be shortened in the case of atrophic rhinitis.
T
The most severe clinical signs of atrophic rhinitis can be seen in suckling piglet
F
Atrophic rhinitis can be prevented by vaccinating the pregnant sows:
T
first time sow x2
older sows x1
The lesions of atrophic rhinitis are examined after sawing the nose behind the first premolar
teeth:
T
Clinical signs of a atrophic rhinitis appear if piglets are infected in the first few weeks of their
life:
T
The mortality and the economic impact of atrophic rhinitis are high:
F
The endotoxin of the agent is responsible for the clinical signs and lesions of atrophic rhinitis
F
Atrophic rhinitis in fattening pigs is caused by Bordetella bronchiseptica
F
In 4-6 months old pigs B. bronchiseptica strains cause severe pneumonia
F
Dermonectotoxin is an important virulence factor of B. bronchiseptica
T
Atrophic rhinitis cannot be prevented with vaccination
F
Block of the lacrimal channel is a typical sign of atrophic rhinitis
T
The dermonecrotoxin producing Pasteurella multocida strains are responsible for the severe
lesions of atrophic rhinitis
T
The dermonecrotoxin of P. multocida inhibits the activity of the osteoclast cells
F
Atrophic rhinitis can be prevented by vaccinating the day-old piglets
F
Atrophy of the turbinate bones is a typical lesion of atrophic rhinitis
T
Isolation of the causative agent from the nose confirm the diagnosis of atrophic rhinitis.
F
The effects of the dermonecrotoxin produced by Pasteurella multocida are reversible
F
Bordetella bronchiseptica and Pasteurella multocida cause atrophic rhinitis
T
Bordetella bronchiseptica causes reversible lesions in the nasal cavity of pigs.
T
Infection of pigs with Bordetella bronchiseptica and Pasteurella multocida at any age can
result in atrophic rhinitis
T-A
but i think false bc infection older = asym carrier
The mortality of atrophic rhinitis can be 50-60%
F
Clinical signs of atrophic rhinitis can be seen if piglets infected first week of life
T
The lesions of atrophic rhinitis are reversible.
T- (F) in A but file v unsure, some lesions are reversible so I think T
The lesions of atrophic rhinitis are caused by an endotoxin
F
Atrophic rhinitis cannot be prevented with vaccination
F
Hungary is free from atrophic rhinitis of swine
F
The clinical form of atrophic rhinitis can be seen if the piglets were few weeks old when
infected
F
below few weeks
Bordetella bronchiseptica causes reversible changes in swine
T
The dermonecrotoxin of Pasteurella multocida damage the osteoclasts
F
At atrophic rhinitis the conchae absorb
T
Isolating Pasteurella multocida from pigs’ noses proves atrophic rhinitis
F
The endotoxin of the agent is responsible for the clinical signs and lesions of atrophic
rhinitis
F
Atrophic rhinitis can be prevented with toxoid vaccine given at weaning.
F
PM lesions of atrophic rhinitis can be examined after transverse cut of the nose.
T
Atrophic rhinitis is examined PM by a longitudinal section of the nose
F
Animals showing signs of atrophic rhinitis remain carriers.
I think T
F in file
) Atrophic rhinitis can be prevented by vaccinating the sow
T
Atrophic rhinitis cause disease in swine and calves
F
Dermonectotocin in case of atrophic rhinitis acts on the osteoblast cells
T
Atrophic rhinitis is caused by a synergistic interaction between B. bronchiseptica and P.
multocida D
T
B. bronchiseptica can cause immunosuppression
F
Toxoid vaccines can be used for prevention of atrophic rhinitis
T
B. bronchiseptica strains producing toxins causing serious lesions
F
The typical PM lesions of atrophic rhinitis are caused by B. bronchiseptica strain
F
Atrophic rhinitis is a common disease that causes severe losses
F
Atrophic rhinitis only occurs pigs that were infected as suckling piglets
T
Atrophic rhinitis is proven by isolating P. multocida
F
Tetracyclines can successfully be used to treat atrophic rhinitis
T
Wrinkles and torsion of nose is the most prominent clinical sign of atrophic rhinitis.
