Presence of interferon and antibodies to BK virus in amniotic fluid of normal pregnant women. 1985

F Taguchi, and J Kajioka, and N Shimada

Paired samples of maternal sera, umbilical cord sera and amniotic fluids were tested for antibodies to BK virus (BKV) and for interferon content. It was found that two out of 14 pregnant women were antibody negative, the latter were estimated to be susceptible to BKV primary infection. In contrast, there was no foetal case among those which were at risk of foetal infection with BKV as judged from the presence of BKV antibody in maternal sera and interferon in the placentas. It might be hypothesized that BKV may be transmitted to the foetus only in the case of BKV primary infection of antibody-negative pregnant women with undetectable amount of interferon (IFN) in the placenta.

UI MeSH Term Description Entries
D007372 Interferons Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions. Interferon
D011120 Polyomavirus A genus of potentially oncogenic viruses of the family POLYOMAVIRIDAE. These viruses are normally present in their natural hosts as latent infections. The virus is oncogenic in hosts different from the species of origin.

D001739 BK Virus A species of POLYOMAVIRUS apparently infecting over 90% of children but not clearly associated with any clinical illness in childhood. The virus remains latent in the body throughout life and can be reactivated under certain circumstances.

D000653 Amniotic Fluid A clear, yellowish liquid that envelopes the FETUS inside the sac of AMNION. In the first trimester, it is likely a transudate of maternal or fetal plasma. In the second trimester, amniotic fluid derives primarily from fetal lung and kidney. Cells or substances in this fluid can be removed for prenatal diagnostic tests (AMNIOCENTESIS).
