Significance of Clostridium difficile and its cytotoxin in children
Insights
Clostridium difficile colonization is common in infants but rarely causes diarrhea. This study suggests environmental exposure, not antibiotic use or diet, is the likely source of C. difficile in children.
Area of Science:
- Microbiology
- Pediatrics
- Infectious Diseases
Background:
- Clostridium difficile is an opportunistic enteric pathogen.
- Understanding C. difficile colonization in children is crucial for public health.
- Previous studies have yielded varying results on C. difficile prevalence in pediatric populations.
Purpose of the Study:
- To investigate the prevalence of Clostridium difficile and its cytotoxin in children across different age groups.
- To explore potential correlations between C. difficile colonization and factors like diarrhea, antibiotic use, diet, and other enteric pathogens.
- To determine the significance of C. difficile as a cause of diarrhea in pediatric populations.
Main Methods:
- Stool samples from 147 children (neonates, infants, older children) were analyzed.
- Detection methods for Clostridium difficile and its cytotoxin were employed.
- Data on diarrhea, antibiotic history, diet, and co-infections were collected and analyzed.
Main Results:
- Clostridium difficile was detected in 5% of premature neonates, 46% of infants, and 4% of older children; none of the full-term neonates were positive.
- Faecal cytotoxin was detected in only 7% of infants.
- No significant correlation was found between C. difficile presence and diarrhea, antibiotic therapy, diet, or other enteric pathogens.
Conclusions:
- Intestinal colonization by Clostridium difficile in children is likely acquired from environmental sources.
- Clostridium difficile is not considered a significant cause of diarrhea in the pediatric population studied.
- Further research into environmental transmission routes of C. difficile in children is warranted.
Abstract:
Stools of 147 children belonging to different age groups were examined for the presence of Clostridium difficile, its cytotoxin and other enteric pathogens. None of the 31 full-term neonates, 5 (16%) of the 32 premature neonates, 27 (46%) of the 59 infants and 1 (4%) of the 25 older children excreted C. difficile in their stools. Faecal cytotoxin was only detected in four infants (7%). There was no correlation with diarrhoea, previous antibiotic therapy, type of diet, or the concomitant presence of other intestinal pathogens. We conclude that colonisation of the intestine by C. difficile is probably acquired from environmental sources and that it cannot be regarded as a significant cause of diarrhoea in children.
