Insights

Staphylococcus aureus and norovirus are the leading causes of acute gastroenteritis in infants following rotavirus vaccination. This study identified common bacterial and viral pathogens contributing to infant AGE.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Microbiology

Background:

  • Rotavirus vaccination has altered the landscape of acute gastroenteritis (AGE) etiology in infants.
  • Understanding current common pathogens is crucial for effective diagnosis and treatment.

Purpose of the Study:

  • To identify the prevalent bacterial and viral pathogens causing acute gastroenteritis in infants.
  • To assess changes in AGE etiology post-rotavirus vaccination.

Main Methods:

  • Stool specimens from infants with acute diarrhea were tested for 10 bacterial and 5 viral pathogens.
  • Clinical symptoms and laboratory data were recorded and compared between bacterial and viral cases.

Main Results:

  • 51.2% of infants tested positive for at least one pathogen.
  • Staphylococcus aureus (31.7%) and norovirus (12.2%) were the most common bacterial and viral pathogens, respectively.
  • Fever and respiratory symptoms were more frequent in viral infection cases.

Conclusions:

  • Staphylococcus aureus and norovirus are currently the primary bacterial and viral agents of AGE in infants.
  • The findings highlight the evolving nature of infectious diarrhea in infants.

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 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,...

Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

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...

Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Healthcare Associated Infections I: Iatrogenic, Exogenic and Endogenic

Healthcare-associated infections (HAIs) occur in a healthcare facility while a person receives care for another ailment. This category also includes work-related infections among healthcare staff.
HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
