Severe clinical signs can be seen during the primary complex phase of tuberculosis
F
no clinical signs
In humans, tularaemia can be diagnosed using serological tests
T
With Köster stain the cells of Brucella are red
T
Wounds on the oral mucosa predispose to necrobacillosis
T
The disease caused by B.bronchiseptica infection in dogs can be prevented using live and inactivated vaccines
F
use live vaccine
Swine typhoid is limited to the gut, the agent does not enter the bloodstream
F
causing septicaemia or bacteremia
the causative agent of chicken coryza spreads via germinative infection
?
B.abortus does not cause a septicaemia
F
Swine oedema disease produces clinical signs slowly. Pigs will idea after a few weeks of onset of sickness
F
sudden onset
Lymphocytes and histiocytes can be found in high numbers in tubercules
T
To prevent the pyosepticaemia of foals, the mares must be vaccinated
F
B.bronchiseptica is capable of causing pneumonia without co-infection
?
Antibiotic treatment can cause an endotoxin shock in cattle in case of E.coli mastitis
F
Avian leukosis disease occurs not only in poultry, but in other bird species as well
T
The insufficient fibre consumption is an important predisposing factor to enteral E.coli infections in rabbits
T
Brucella ovis causes abortion in goats

sheep only
The main virulence factors of actinobacillus pleuropneumonia are cytotoxins
T
The European brown hare is a recipient species of tularaemia
F
In the case of equine influenza, mares must be withdrawn from breeding due to long-term carriage
F
Human brucellosis has been eradicated due to efficient control measures
F?
Weaned piglets diarrhoea is caused by enteropathogenic E.coli (EPEC) strains
F
caused by enterotoxogenic E. coli in 0-10 day old piglet

T
The primary complex is generally seen in the gut of the cattle
F
seen in the lungs of cattle, gut of swine
Bird flu infection can be transmitted through direct contact, saliva, faeces and natural waters
T
The causative agent of CEM cannot be cultured
F
Pseudotuberculosis is limited to the gut
F
The antibodies against Francisella tularensis can be detected using serum plate agglutination in the recipient species
F
Septicaemia caused by pasteurellae is frequent in adult sheep
F
ocurs in suckling lamb under 3 months
Bovine respiratory Pasteurellosis appears as an interstitial pneumonia

using pure culture
