Titrations of complement fixing antibody (c.f.a.) were done in paired sera of 127 women at delivery and cord blood of their babies using two different cytomegalovirus strains both of which had undergone many passages in WI-38 cells, With High strain 74% of the mother and 41% of the babies were negative at the serum dilution 1:4. With Towne strain the incidence of negative was 5% both among the mother and the newborns. Worth of mention is the study of correlation of the titers in the matched pairs of sera according to the strain. With High strain 23 of the babies had c.f.a. titers significantly higher than their mothers and 14 of them were from negative women. This situation could be suggestive of an active placental transfer of IgG globulins. No such disparities were found using Towne strain as antigen. 48 pairs of sera were then tested with both strains by indirect hemagglutination, indirect immunofluorescence and gel precipitin test. Results are discussed in relation to the possible differences in the antigenic composition of the two cytomegalovirus strains.

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
