Salmonella gastroenteritis in children was common, with Salmonella serogroup B strains most frequent. Bloody diarrhea occurred more with group B Salmonella infections, but severe outcomes were rare.

Area of Science:

  • Pediatric Infectious Diseases
  • Microbiology
  • Epidemiology

Background:

  • Salmonella gastroenteritis is a significant cause of childhood diarrhea.
  • Understanding the epidemiology and clinical features of Salmonella infections is crucial for effective management.

Purpose of the Study:

  • To analyze the epidemiological characteristics, clinical presentation, and outcomes of Salmonella gastroenteritis in hospitalized children.
  • To identify trends in Salmonella serogroups and serotypes over time.

Main Methods:

  • Retrospective analysis of 508 Salmonella strains isolated from 20,100 children with gastroenteritis.
  • Review of patient data including clinical symptoms, laboratory findings, and treatment outcomes.

Main Results:

  • Salmonella accounted for 2.5% of diarrheal cases, with peak incidence from June to October.
  • Salmonella serogroup B was most common (77%), followed by D (21%) and C (2%). S. typhimurium was the predominant serotype (52%).
  • Bloody diarrhea was observed in 27% of cases, significantly higher in group B infections (30% vs. 15%, p < 0.05). Severe dehydration and complications were rare.

Conclusions:

  • Salmonella gastroenteritis is a notable cause of pediatric diarrhea, with distinct epidemiological patterns.
  • Serogroup B strains, particularly S. typhimurium, were dominant, and associated with a higher risk of bloody diarrhea.
  • Despite high incidence, Salmonella gastroenteritis in this cohort had a favorable prognosis with minimal severe complications or mortality.
