Optimal timing is between 27 and 36 weeks gestation to maximize the maternal antibody
response and passive antibody transfer to the infant.
Inhibitory effect of maternal antibody
on mother-to-child transmission of human T-lymphotropic virus type I.
In the control group, average maternal antibody
levels were as high as 8 of HI antibody titer at hatch and thereafter decreased quickly.
The maximum increase has occurred at 20-30th days of the disease, but antibody increase has not happened in infants younger than 4 months of age who had high maternal antibody
Laboratory criteria for diagnosis of CRS were: demonstration of rubella-specific IgM antibody in cord blood, or demonstration of rubella-specific IgM antibody in infant blood at 8th wk of age, or infant rubella antibody level persisting at a higher level and for a longer period than expected from passive transfer of maternal antibody
This variable rate of maternal antibody
decline makes the timing of vaccine administration difficult.
Researchers there are targeting two opposing forces affecting neonate health: the need for effective passive transfer of maternal antibodies and the maternal antibody
interference that hinders the newborn's ability to develop vaccine-based immunity to common pathogens.
A major factor protecting infants from developing disseminated herpes is the presence of maternal antibody
, but acyclovir may diminish antibody response to HSV.
This immune reaction can trigger a maternal antibody
response in subsequent RhD-positive pregnancies, causing the breakdown of fetal red blood cells.
In our study titre of maternal antibody
in ABO HDFN was positively correlated with grades of DAT, risk related to peak bilirubin levels, severity of disease and intensity of treatment and was negatively correlated with cord blood haemoglobin levels.
transferred to the young infant has an antibody half-life that provides adequate protection during the first 2 months of life, when the infant is especially vulnerable to pertussis infection.
Antibody titers of chicks in unvaccinated controls Group E: On day 07, a total of 10 chicks had maternal antibody
titer of 1: 2 each; 07 chicks a titer of 1: 4 and of 03 chicks each indicated a titer of 1: 8 H9N2 virus.
