Insights

Human parvovirus B19 infection is unlikely to cause premature birth. Testing umbilical cord blood from premature infants found no evidence of parvovirus B19 infection, suggesting it is not a cause of preterm birth.

Area of Science:

  • Obstetrics and Gynecology
  • Virology
  • Neonatology

Background:

  • Human parvovirus B19 is a common virus that can infect pregnant women.
  • Intrauterine infection with parvovirus B19 has been suspected as a cause of adverse pregnancy outcomes, including premature birth.

Purpose of the Study:

  • To investigate the association between intrauterine parvovirus B19 infection and premature birth.
  • To evaluate the presence of parvovirus B19 antibodies and DNA in umbilical cord blood of premature infants.

Main Methods:

  • Enzyme-linked immunosorbent assays (ELISA) were used to detect B19-specific IgM antibodies.
  • Polymerase chain reaction (PCR) assays were performed to detect parvovirus B19 DNA.
  • Samples were obtained from the umbilical cord blood of 76 premature infants.

Main Results:

  • No parvovirus B19 DNA was detected in any of the umbilical cord blood samples.
  • No samples tested positive for anti-parvovirus B19 IgM antibodies.
  • The study found no evidence of intrauterine parvovirus B19 infection in the cohort.

Conclusions:

  • Intrauterine parvovirus B19 infection is unlikely to be a significant cause of premature birth.
  • Further research may be needed to fully understand the role of parvovirus B19 in pregnancy complications.

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...

Respiratory Syncytial Virus Disease

Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...

Poliomyelitis

Poliomyelitis is caused by poliovirus, a small, non-enveloped, positive-sense RNA virus of the Picornaviridae family and Enterovirus genus. Transmission occurs primarily via the fecal-oral route, often through ingestion of contaminated water or food. The virus initially replicates in the oropharynx and intestinal mucosa, particularly in lymphoid tissues such as the tonsils, Peyer’s patches, and regional lymph nodes. Primary viremia follows, allowing dissemination throughout the body.In most...

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...
