Summary

Non-typhoid Salmonella gastroenteritis in Malaysian infants often presents with fever and vomiting. Early antibiotic treatment is recommended for infants under six months with fever and dehydration due to invasive complication risks.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Microbiology

Background:

  • Non-typhoid Salmonella gastroenteritis is a common childhood illness.
  • Invasive complications can lead to severe outcomes in pediatric patients.
  • Understanding risk factors and serotypes is crucial for effective management.

Purpose of the Study:

  • To investigate clinical features of Salmonella gastroenteritis in Malaysian children.
  • To determine the incidence, risk factors, and outcomes of invasive Salmonella infections.
  • To identify prevalent Salmonella serotypes and their antibiotic susceptibility patterns.

Main Methods:

  • Retrospective review of 131 pediatric cases of non-typhoid Salmonella gastroenteritis.
  • Data collected from University Hospital, Kuala Lumpur, between 1994 and 1996.

  • Analysis of clinical presentation, complications, serotypes, and antibiotic sensitivity.
  • Main Results:

    • Infants under one year constituted 67% of cases.
    • Fever and vomiting were common symptoms.
    • Invasive complications (bacteremia, meningitis) occurred in 5.3% of children.
    • Younger age (under 6 months), high fever, and dehydration were associated with invasive disease.
    • Common serotypes included S. enteritidis, S. paratyphi B, and S. bovis-morbificans.
    • Isolates showed high susceptibility (94-100%) to common antibiotics.

    Conclusions:

    • Salmonella gastroenteritis in infants requires vigilant monitoring for invasive complications.
    • Empirical antibiotic treatment is advised for febrile, dehydrated infants under six months pending blood culture results.
    • Knowledge of local Salmonella serotypes and resistance patterns informs clinical practice.
