Mycobacteria can be stained with Ziehl- Neelsen staining.
T.
Mycobacteria are highly resistant thanks to lipids + waxes in cell wall.
T.
Obligate pathogenic Mycobacteria can occur + replicate in environment.
F.
There is a close Ag relationship between Mycobacteria.
T.
Mycobacteria are IC bacteria.
T.
Giant cells typically occur in tubercles.
T.
If the resistance of animal is high, mainly exudative lesions of tuberculosis can be seen.
F.
The 1º complex Bo tuberculosis is generally seen in GI tract.
F.
The tuberculin test is used for the detection of infection of animals with Mycobacteria.
T.
The thermal tuberculin test can be used in order to examine organic reaction of?
T.
Ab against Mycobacteria are detected in the tuberculin test.
F.
If the tuberculin is -ve, it has to be repeated immediately.
F.
False +ve of tuberculin test can be caused by
?

F.
Dermatophilosis occurs mainly in moderate climate especially in winter.
F.
Dermatophilus congolensis is the agent of Dermatophilosis.

F.
Exudative pustular dermatitis is the main CS of Dermatophilosis.
T.
Coli Diarrhea of New- born Calves is caused by entero- toxigenic E. coli strains.
T.
Hygienic problems can predispose to Coli Diarrhea of New- born alves.
T.
Severe encrotic enteritis occurs in the case of Coli Diarrhea of New- born Calves.
F.
Coli Diarrhea of New- born Calves can be prevented by vaccinating the pregnant cows.
T.
Oedema Disease is caused by enteropathogenic E. coli strains.
F.
Enterotoxins are responsible for the CS + lesions of oedema disease.
F.
Oedema disease generally occurs 1- 2 wks after weaning.
T.
There is widespread vaccination for the prevention of oedema disease.
F.
Omphalitis is a frequent sign of E. coli disease of d- old chicks.
T.
Pericarditis + perihepatitis are frequent PM lesions caused by E. coli.
T.
Certain vero- toxigenic E. coli can be zoonotic.
