Insights

Mycoplasma infection in stillborns and newborns is linked to congenital malformations and organ damage. Urogenital mycoplasmas may cause teratogenic effects on the developing human fetus.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatology
  • Infectious Diseases

Context:

  • Mycoplasmas are common human pathogens.
  • Congenital infections can lead to severe neonatal complications.
  • Previous studies have suggested a link between mycoplasmal infections and adverse pregnancy outcomes.

Purpose:

  • To investigate the pathological effects of mycoplasmal infections in stillborn and dying newborn infants.
  • To determine the etiological role of Mycoplasma hominis and Mycoplasma pneumoniae in congenital malformations.
  • To explore the potential teratogenic effects of urogenital mycoplasmas on the human fetus.

Summary:

  • The study examined 18 stillborns and dying newborns infected with mycoplasmas, using direct Coons method for etiological diagnosis.
  • A significant 50% of mycoplasma-infected infants exhibited congenital malformations.
  • Histological and histochemical analyses revealed circulatory disorders and degenerative changes in brains and organs, indicating a pathological process.

Impact:

  • Mycoplasmal infections acquired in utero or during delivery are likely pathogenic.
  • Findings suggest urogenital mycoplasmas may have teratogenic effects, contributing to fetal development abnormalities.
  • This research highlights the importance of identifying and managing mycoplasmal infections during pregnancy to prevent congenital anomalies.

Meiosis vs. Mitosis

Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...
Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...

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...
Malaria01:29

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
Toxoplasmosis01:28

Toxoplasmosis

Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
