Course of Infectious Diseases Flashcards
Viruses causing generalised diseases generally replicate at the place of entry and in the
regional lymph nodes
T
The lesions are at the place of entry of the agent in the case of local infections
T
In the case of a local infection the site of entry and the lesions are at the same place
T
Lesions can be seen in different organs in the case of generalised diseases
T
Intra uterine infection can result immune tolerance in the case of some diseases
T
Intra uterine infection can result embryonic death in the case of some diseases
T
Intra uterine infection does not occur since the placenta protects the foetus
F
Fetuses cannot be infested since the placenta completely isolates them.
F
The incubation time is the time between the appearance of the clinical signs and death
of the animal
F
The incubation time is the time between infection and the appearance of clinical signs.
T
The incubation time lasts from the infection till the manifestation of the clinical signs
T
Some infective agents have immunosuppressive effect
T
Some infective agents can cause malformation of fetuses.
T
Subacute diseases last one or 2 days.
F
Intra uterine infections does not occur in mammals since the agents cannot penetrate
the placenta.
