Passive immunisation Flashcards
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
F
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 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
Animals with epitheliochorial placenta have maternal immunity only from colostrum
T
The endotheliochorial placenta prevents to transport of immunoglobulins to the foetus
F
Homologous hyperimmune serum can provide about a year-long protection.
