[Yersinia and infantile gastroenteritis]
Insights
This study investigated intestinal pathogens in pediatric patients with prolonged diarrhea. Rare Yersinia strains were identified, suggesting their potential role in these gastrointestinal infections.
Area of Science:
- Microbiology
- Pediatric Gastroenterology
- Infectious Diseases
Background:
- Protracted diarrhea with blood and mucus in pediatric patients necessitates thorough etiological investigation.
- Identifying causative agents is crucial for effective treatment and understanding disease transmission.
Observation:
- Fecal and intestinal mucosal biopsy samples from 16 pediatric patients were analyzed.
- Specific Yersinia strains, including Yersinia enterocolitica and Yersinia intermedia, were isolated.
- Aeromonas hydrophila was also detected in some samples.
Findings:
- Yersinia enterocolitica (1/5/XZ) and Yersinia intermedia (1/18/XZ) were isolated from two patients' fecal samples.
- Yersinia enterocolitica (1/5/XZ) and a self-agglutinable variant were found in another child's fecal and biopsy samples.
- The identified Yersinia strains are uncommon in human infections, highlighting their potential significance.
Implications:
- These findings suggest that uncommon Yersinia strains may be implicated in pediatric protracted diarrhea.
- Further research is needed to elucidate the pathogenicity and clinical relevance of these specific Yersinia isolates.
- This study contributes to the understanding of rare enteric pathogens in pediatric populations.
Abstract:
Fecal samples and intestinal mucosal biopsies of 16 patients in paediatric age, with protracted diarrhoea with blood and mucus, were examined for intestinal pathogens including Yersinia. Yersinia enterocolitica 1/5/XZ and Yersinia intermedia 1/18/XZ were isolated from fecal samples of two patients. In another child, Yersinia enterocolitica, 1/5/XZ was isolated from fecal sample, while Yersinia enterocolitica 1/self-agglutinable/XZ from colon biopsy. The other intestinal pathogens were absent; Aeromonas hydrophila however was isolated from two fecal samples. The Yersinia strains isolated are not frequently found in human infections.
