Intestinal occurrence of Campylobacter fetus subspecies jejuni and Clostridium difficile in children in Sweden

Insights

Campylobacter jejuni is rarely found in Swedish children with diarrhea, unlike Clostridium difficile, which is common in healthy infants and considered normal flora.

Area of Science:

  • Microbiology
  • Pediatrics
  • Gastroenterology

Background:

  • Investigating the prevalence of enteric pathogens in pediatric populations is crucial for understanding childhood gastrointestinal illnesses.
  • Campylobacter jejuni and Clostridium difficile are significant causes of diarrhea in various age groups, necessitating accurate diagnostic and epidemiological data.

Purpose of the Study:

  • To determine the occurrence of Campylobacter jejuni and Clostridium difficile in stool samples from children aged 0-6 years in Sweden.
  • To assess the association of these bacteria with diarrhea and antibiotic treatment in pediatric patients.

Main Methods:

  • Stool samples were collected from 356 children across different health statuses and age groups (birth to six years).
  • Bacterial cultures were performed to isolate and identify Campylobacter jejuni and Clostridium difficile.

Main Results:

  • Campylobacter jejuni was isolated from 2 of 56 children with diarrhea, but not from healthy children or those recently treated with antibiotics.
  • Clostridium difficile was isolated from 17% of healthy children aged 1 week to 1 year and 1% of perinatal children.
  • Similar isolation rates for Clostridium difficile were observed in children with diarrhea and those treated with antibiotics, with most isolates (29/34) from infants under one year old.

Conclusions:

  • Campylobacter jejuni is not a common cause of diarrhea in Swedish children and is not part of the normal fecal flora.
  • Clostridium difficile is frequently found in the stools of healthy infants and should generally be considered a normal finding in children.

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 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 the skin...
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 receptor...
