Epi Mix B 201-400 Flashcards
Use of antibiotics in the case of diseases caused by viruses is not allowed because of antibiotic resistance

In case of import of animals into a farm, animals in the quarantine must be tested for infections
T
In case of import of animals into a farm, animals in the quarantine must only be observed, there is nothing to do with them if they do not show clinical signs
F
Only eggs from the same flock are allowed to be hatches in one hatching machine
T
Eggs of different species can be hatched together; they cannot infect each other thanks to the different hatching time
F
All-in-all-out is an important principle in prevention of infectious diseases
T
Isolation of age groups is an important way of prevention of infectious diseases
T
”All-in-all-out” principle is a general epidemiological rule
T
Isolated keeping of different animal species can prevent the spreading of infectious diseases
T
Isolated keeping of different age groups of the same species cannot prevent spreading of infectious diseases since all animals of the same species are susceptible to the same agents
F
Day-old birds cannot be infected in the hatchery because they are protected by yolk Immunity.
F
The immunoglobulin content of the colostrum is continuously decreasing after farrowing
T
Maternal antibodies can inhibit the active immune response.
T
There is no maternal protection in birds
F
Maternal protection occurs only in mammals
F
Colostrum is the main way of maternal protection in the case of animals with epitheliochorial placenta
T
The half-life of the heterologous hyperimmune serum is about 7-10 days
T
The half-life of the heterologous hyperimmune serum is about 2-3 weeks
T
Animals having epitheliochorial placenta receive maternal antibodies only through the placenta
F
Animals having epitheliochorial placenta receive maternal antibodies only through the colostrum
T
Enteral lymphocytes of the dam can be transferred to the offspring in colostrum
T
The immunoglobulin content of the colostrum is influenced by the nutrition of the dam
T
The protein and antibody content of the colostrum is stable in the first week after calving
F
Absorption of maternal antibodies from the colostrum in the first three days is not changing
F
Colostrum is not important in protection of calves since the antibodies can go through the placenta
F
Colostrum is the only way of receiving maternal protection in calves
T
The immunoglobulin content of the colostrum is not changed in the first week after birth
F
Calves can absorb maternal antibodies for a week after birth
F
Maternal antibodies can inhibit certain immunization
T
New-born animals cannot be infected from the milk thanks to the colostral antibodies.
F
The colostrum contains maternal lymphocytes
T
The protein content of the colostrum remains high for the first two weeks after giving birth
F
The immune globulin content of the colostrum remains high for the first week after giving birth.
F
The enteral absorption of immune globulins is decreasing after birth
T
Maternal antibodies can decrease the efficacy of vaccination.
T
The immune globulin concentration of the colostrum decreases sharply after birth
T
The enteral absorption of immunoglobulins is about the same for a week after birth
F
The maternal antibodies can decrease the immune response against vaccines
T
Enteral lymphocytes can get from the dam to the newborn animal with colostrum
T
The endotheliochorial placenta prevents the transport of immunoglobulins to the foetus
F
Homologous hyperimmune serum can provide about a year-long protection
F
Strains used in marker vaccines can be differentiated from the field strains.
T
Avirulent strains can be used in live vaccines
T
The health state of the vaccinated animals can influence the efficacy of the vaccination
T
Adjuvants in vaccines increase the shelf life of vaccines
F
Inactivated vaccines contain inactivated bacterial toxins
T
The method of vaccination has no effect on the efficacy of the vaccination
F
Adjuvants in vaccines increase the efficacy of vaccines
T
Attenuated strains can be used in live vaccines.
T
Deletion vaccines can only be used as live vaccines
F
Inactivated vaccines can contain the whole agents or their components
T
The colostral immunoglobulins have no effect on the vaccination of the new born animals
F
DIVA principle can only be used if the animals are vaccinated with deletion vaccines
F
According to DIVA principle, infected and vaccinated animals can be differentiated
T
Subunit vaccines contain only antigens of the agents
T
Certain parts of the genome are missing from deletion vaccine strains
T
Some genes are missing from the strains included in deletion vaccines
T
For safety reasons only inactivated vaccines are used
F
Live vaccines can contain strains with lower virulence
T
Live vaccines always contain avirulent agents
F
Live vaccines are less effective than the inactivated ones
F
Live vaccines are dangerous, they are not on the market any more
F
Live vaccines are not used in Europe any more
F
Live vaccines do not provide good immunity
F
Marker vaccines are used to mark the site of vaccination
F
It is not allowed to use inactivated deletion vaccines in the EU
F
Live vaccines contain attenuated or avirulent agents
T
The agent in a vaccine can influence the level of the immune response of vaccinated animals.
T
If deletion vaccines are used, vaccinated and infected animals can be differentiated
T
Using marker vaccines, vaccinated and infected animals can be differentiated.
T
Use of marker vaccines can be combined with “test and remove” eradication
T
Marker vaccines are marked with
F
