MT3- Corynebacteria Flashcards
Phospholipase D is a virulence factor of C. pseudo tuberculosis
T
In Corynebacterium pseudotuberculosis oedema of the chest is common
T
Corynebacterium pseudotuberculosis can be transmitted between goats and horses
F
Pseudotuberculosis does not occur in Hungary.
F
In pseudotuberculosis, only submandibular lymph nodes of sheep are affected.
F
In pseudotuberculosis oedema of the limbs is common
T
Corynebacterium pseudotuberculosis causes caseous lymphadenitis
T
Corynebacterium pseudotuberculosis forms due to dipping of sheep
T
The agent of caseous lymphadenitis can cause generalised infection in sheep
T
Caseous lymphadenitis of sheep occurs in tropical countries but not in Europe
F
- worldwide (except Australia and new-zeeland
Arthritis can be a clinical sign of caseous lymphadenitis of sheep
T
- lambs mainly : arthritis , peri arthritis
Caseous lymphadenitis of sheep is caused by Corynebacterium pseudotuberculosis
T
Corynebacterium pseudotuberculosis produces phospholipase D toxin
T
- it damage the erythrocytes + endothelial cells
The agent of Caseous lymphadenitis of sheep can be transmitted to horses and it will cause ulcerative lymphangitis
F
Caseous lymphadenitis does not occur in goats and cattle
F
- occurse in farm animals
Caseous lymphadenitis of sheep is an acute disease
F
Clinical signs of caseous lymphadenitis of sheep can be seen only above 3-4 months
T
Clinical signs of caseous lymphadenitis can only be seen in sheep
F
Caseous Lymphadenitis of sheep is mainly seen in suckling lamb
F
Mycolic acid and lipoids in the cells wall of Corynebacterium pseudotuberculosis contribute
to the virulence of the bacterium
T
Lesions of caseous lymphadenitis of sheep can be seen only in the lymph nodes.
F
Caseous lymphadenitis can occur only in sheep
F
Caseous lymphadenitis is caused by nitrate positive strains of Corynebacterium pseudotuberculosis
F
nitrate - : sheep and goat (Caseous lymphadenitis)
nitrate +: horse ( Ulcerative lymphangitis) and cattle (..)
Vaccination can be used for the prevention of caseous lymphadenitis
T
Caseous lymphadenitis is caused by nitrate-negative Corynebacterium pseudotuberculosis
strains
T
nitrate - : sheep and goat (Caseous lymphadenitis)
Wound infection can predispose to caseous lymphadenitis
T
Caseous lymphadenitis can be generalized in sheep
T
Antibiotics cannot be used for the treatment of caseous lymphadenitis
F
Treatment: Antibiotics (penicillin, tetracyline, erythromycin)
Phospholipase D is an important virulence factor of the agent of caseous lymphadenitis
T
Abscesses in the lymph nodes are typical lesions of caseous lymphadenitis
T
Skin abscess - fistula - scar
Caseous lymphangitis is nitrate negative
T
Corynebacterium pseudotuberculosis causes caseous lymphadenitis in goats
T (goat and sheep)
Abortion can be a clinical sign of caseous lymphangitis
T
- fever, anaemia
- skin abscess- fistula- scar
- arthritis in lambs
- abortion
Caseous lymphadenitis of sheep occur only in the tropic
F
- worldwide ( except Australia and new Zealand)
- warmer climate mor frequent
