2.Bacillus anthracis and aerobic spore-forming bacteria. Clostridium. Flashcards
Spores of bacilli are widespread in our environment.
T
B.Anthracis is a facultative pathogenic bacterium
F,obligate
B.Anthracis is a flagellated bacterium
F
B.Anthrao is produce spore in the host body
T
Bacilli are obligate anaerobic bacteria
F, obligate aerobe, facultative anaerobe
Capsule of B.anthrac is stain pink as a result of toluidine blue staining
T
chicken necrotic enteritis is caused by c.colinum
F
Necrotic enteritis of piglets is caused by c.perfringens D
F
Black Leg is caused by C.chauvoei
T
Toxin of C.botulinum causes rigid paralysis in…?
F, flaccid paralysis
The vegetative bacteria of the bacillus anthracis are widely distributed in the normal intestinal surface and on the mucosal surfaces of domestic animals especially Ru.
F
B.anthracis is an obligate aerobic bacterium but for the capsule forming 0 is also
required
T
There are cross rx with B.cereus by using Ascoli-test to detect B.anthracis
T
Horses are resistant to B.anthracis
F, mostly herbivores get it
B.anthracis and B.cereus can be differentiated by their hemolysis
T,
B.Thuringiensis is the causative agent of american foublood of honeybees
F, B.larvae
One causative agent of malignant edema is C.histolyticum?
T
c.perfringens belongs to the group neurotoxic clostridia
F
The toxin of the c.botulinum is quite resistant to heat treatment
T
The spores of B.Anthracis are widely distributed in the soil and natural waters of endemic areas
T
A bacillus anthracis is an obligate anaerobic bacterium O2 is needed only for the
spore production
F, obligate aerobe
By using toludine blue staining in a smear of B.anthracis we can see pink rods in chains surrounded by blue capsular material
False
Paenibacillus polymixa as an insect pathogen causes the american foublood of the
Honeybees
F
Clostridium difficile belongs to the group histotoxic clostridia
F
The necrotic enteritis in chicken and the calf enterotoxaemia are caused by the same bacterium species
True
The causative agent of the Lamb dysentery is a flagellated bacterium
F
one causative agent of malignant edema is c.difficile
F
The toxin of the c.tetani causes flaccid paralysis
F
C.piliforme cannot be cultured on artificial media
T
The pulpy kidney disease (sheep enterotoxaemia) and the necrotic enteritis of chickens are caused by the same bacterium species
T, C.perfringens
