passive immunity

Question 1

neonatal responses

Answer 1

30 days-12 months for full competency
neutrophils and macrophage functions deficient
low B cells
IL-10 (immunosuppressant) more active

Question 2

what animals have no placental transfer of AB

Answer 2

horses and cows

Question 3

What is colostrum

Answer 3

first udderfull of milk full of antibodies
IgG
derived from serum

Question 4

passive immunity

Answer 4

immunity to recipient from an immune donor
humoral factors
temporary acquisition
no active response

Question 5

what effect on neonatal IgG does colostral IgG have

Answer 5

down regulatory

lots of antibody come in, negative feedback loop activated stoping antibody production

Question 6

What happens in failure of passive transfer

Answer 6

inverse relation between passive transfer of immunity and mortality
adequate amounts of Ig transfer may still not mean production
failure of timely ingestion
