Insights

A novel virus causing infant conjunctivitis was isolated from an infant's eye discharge. This agent, resembling trachoma virus, successfully induced similar symptoms in monkey eyes.

Area of Science:

  • Ophthalmology
  • Virology
  • Neonatal Medicine

Background:

  • Acute conjunctivitis is a common neonatal infection.
  • Inclusion conjunctivitis in infants can be caused by Chlamydia trachomatis.
  • The etiology of some conjunctivitis cases remains unclear.

Purpose of the Study:

  • To identify the causative agent of acute conjunctivitis in a neonate.
  • To characterize the isolated pathogen and its potential to cause disease.

Main Methods:

  • Microscopic examination of conjunctival discharge for elementary-body inclusions.
  • Viral culture from conjunctival scrapings using embryonated eggs.
  • Experimental induction of conjunctivitis in monkey eyes.

Main Results:

  • Typical elementary-body inclusions were observed in the infant's discharge.
  • A virus, similar to trachoma virus, was successfully isolated and cultured.
  • Instillation of the cultured virus into monkey eyes caused acute conjunctivitis.

Conclusions:

  • A viral agent, distinct from Chlamydia, was implicated in this case of infant conjunctivitis.
  • The isolated virus demonstrated pathogenicity in an animal model.
  • Further investigation is needed to understand the prevalence and characteristics of this viral pathogen.

Transcytosis of IgG01:15

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...
Sexually Transmitted Infections01:26

Sexually Transmitted Infections

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
