Insights

Recent advances reveal similar immune mechanisms for norovirus and rotavirus susceptibility in children. Understanding these pediatric enteric viral pathogens aids in developing targeted public health interventions and vaccines.

Area of Science:

  • Pediatric Infectious Diseases
  • Virology
  • Immunology

Background:

  • Rotavirus vaccination has reduced severe gastroenteritis, highlighting the burden of norovirus in children.
  • Norovirus is a significant pediatric enteric viral pathogen requiring further research and vaccine development.

Purpose of the Study:

  • To review recent advancements in understanding acquired immunity and susceptibility to norovirus and rotavirus.
  • To update on norovirus vaccine development efforts.
  • To explore shared immunologic mechanisms between norovirus and rotavirus.

Main Methods:

  • Literature review of recent studies on pediatric enteric viral pathogens.
  • Analysis of immunological mechanisms of susceptibility.
  • Examination of vaccine development progress for norovirus.

Main Results:

  • Decline in rotavirus disease unmasks norovirus burden.
  • Norovirus vaccine development is progressing.
  • Shared susceptibility mechanisms, including histo-blood group associations, identified for both viruses.
  • These associations may be genotype-specific.

Conclusions:

  • Understanding shared immunity and susceptibility mechanisms is crucial for developing effective interventions.
  • This knowledge can guide public health strategies against pediatric enteric viral infections.
  • Tailored interventions and vaccine development can be informed by these findings.

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,...

Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Development of Immunocompetence01:22

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...

Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

Human Virome01:26

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
