T
Avian tuberculosis is mainly seen in chicken below 2 months of age
F
Old birds only
In case of avian tuberculosis tubercles can be seen in liver and spleen
T
Avian tuberculosis is treated with penicillin and tetracyclines
F
no treatment
Only Mycobacterium avium subsp. Avium can infect birds
F
M. avium subsp. silvaticum, M. tuberculosis causes tuberculosis in birds
Avian tuberculosis has been eradicated in Europe
F
worldwide
Avian tuberculosis can be typically seen in old, adult birds
T
Mycobacterium tuberculosis can cause clinical signs in some bird species
T
Not very typical
The agent of avian tuberculosis cannot survive in the Environment, its resistance is low
F
Avian tuberculosis usually occurs at 6-8 weeks of age
F
Avian tuberculosis result in local processes
F
Generalised infection
Avian tuberculosis can be diagnosed by slide agglutination or ELISA
T
Can be misguiding
Avian tuberculosis is a common disease in large scale farms causing high economic losses
F
Waterfowl are more susceptible to avian tuberculosis
F
Crepitation during liver transection is characteristic for avian tuberculosis
F
Tuberculosis of poultry occur mainly in breeder flocks
T
Avian tuberculosis occur over 1 year of age
T
The tuberculin test is unreliable in poultry
T
The agent of paratuberculosis is a facultative intracellular bacterium
T
bligate pathogen and facultative intracellular
Paratuberculosis is caused by Mycobacterium avium subsp. Paratuberculosis
T
The agent of paratuberculosis is shed in the faeces
T
feaces+milk
Aerosol infection is the main form of transmission of paratuberculosis
F
The resistance of the agent of paratuberculosis is low, it cannot survive in the environment
F
long survival in the environment: 6-9 months
Paratuberculosis occurs most frequently in pigs
F
Cattle is most susceptible, but also sheep and goats are main hosts
Clinical signs of paratuberculosis can mainly be seen only in those cases that were infected inthe first six months of life
T
Infection over 6 months of life = asymptomatic, but shedding
Fibrinous pneumonia is a typical lesion of paratuberculosis
F
The agent of paratuberculosis is shed only after the appearance of the clinical signs
F
shedding happens 3-5 months after infection, BEFORE clinical signs
Postmortem lesions of paratuberculosis can be seen in the small intestine
T
The most severe clinical signs of Paratuberculosis can be seen in suckling calves
F
Symptoms appear at 2-5 years of age, typically after 2nd or 3rd calving
Lesions are seen in the lungs of animals infected with paratuberculosis
F
Intestines
Paratuberculosis has been eradicated from Europe
F
Worldwide
The clinical signs of paratuberculosis is more severe in calves than in adults
F
Symptoms appear at 2-5 years of age
Dyspnoea and nasal discharge are the main clinical signs of paratuberculosis
F
Main clinical signs is diarrhoea, hunched back
Paratuberculosis occurs mainly in the tropical and subtropical countries
F
Worldwide
The agent of paratuberculosis is shed in the faces and milk
T
The clinical signs of paratuberculosis are more severe in sheep than cattle
F
In sheep and goats clinical signs are less frequent
Paratuberculosis is seen in young calves
F
Symptoms appear at 2-5 years of age
Lesions of paratuberculosis are localized in the small intestine
T
In the case of paratuberculosis tuberculi can be seen in the anterior lobes of the lungs
F
Paratuberculosis can be treated with polymyxins
F
No treatment
Paratuberculosis is seen cows above 2 years of age
T
Symptoms appear at 2-5 years of age
Lesions of the paratuberculosis are localized in the small and large intestine
T
F in A file but in lecture notes the lesions are in the SI+prox LI
Mainly small intestines, sometimes proximal large intestines
In the case of paratuberculosis no tuberculi are seen
T
Weight loss is a typical sign of paratuberculosis
T
In paratuberculosis, the nodules are seen primarily in the large intestine
F
Small intestines
Paratuberculosis can be demonstrated by LST during early stages of infection
T
The agent of avian tuberculosis is an obligate pathogenic bacterium.
T- cant see in file
Paratuberculosis can be prevented by early vaccination of the calves
T
Paratuberculosis can be treated with penicillin and enrofloxacin
F
No treatment
Paratuberculosis can be prevented by vaccination
T
Paratuberculosis is believed to cause Chron’s disease
T
Young animals are resistant to paratuberculosis
F
Paratuberculosis is also called Johne’s disease
T
Paratuberculosis is a chronic disease with diarrhoea affecting mainly ruminants
T
The disease paratuberculosis can develop in animals above 2 months
F
Paratuberculosis can be prevented by vaccination only in countries where it is eradicated
F-A
In Paratuberculosis, nodules can be found in intestinum crassum
F- file unsure but google says intestinum crassum is the distal LI so F would be right bc its SI + prox LI
Young animals are more susceptible to paratuberculosis
T
Paratuberculosis virulence factor is phospholipase C
T- in file but not found in my notes
Paratuberculosis cause proliferative enteritis in small intestines
T
Cattle paratuberculosis shows more severe lesions than sheep/goat
T
Wasting is the main clinical sign (paratuberculosis)
