Detection of enteric campylobacteriosis in children

Insights

Campylobacter fetus subsp. jejuni is a common cause of acute gastroenteritis in young children. Infections are typically mild and resolve within a week, with isolates showing antibiotic sensitivity.

Area of Science:

  • Microbiology
  • Pediatrics
  • Infectious Diseases

Background:

  • Campylobacter fetus subsp. jejuni is a significant bacterial pathogen.
  • Gastroenteritis is a common illness in young children.

Purpose of the Study:

  • To investigate the prevalence and clinical significance of Campylobacter fetus subsp. jejuni in children.
  • To assess the antibiotic susceptibility and phage susceptibility of C. fetus subsp. jejuni isolates.

Main Methods:

  • Bacterial culture and identification from stool samples of symptomatic and asymptomatic children.
  • Clinical data collection on illness duration and severity.
  • Antibiotic susceptibility testing.
  • Bacteriophage typing of bacterial isolates.

Main Results:

  • C. fetus subsp. jejuni was identified as the sole pathogen in 31% of young children (0-8 months) with acute gastroenteritis.
  • Recovery rates in older children (8-24 months) were 38% in symptomatic and 40% in asymptomatic cases.
  • Infections were generally benign, lasting less than a week, with one case of bacteremia.
  • Isolates were sensitive to common antibiotics and 73% were lysed by a specific bacteriophage.
  • Some phage-resistant strains carried phages capable of lysing the reference strain.

Conclusions:

  • Campylobacter fetus subsp. jejuni is a frequent cause of gastroenteritis in infants and young children.
  • The infection typically presents with mild, self-limiting symptoms.
  • Antibiotic sensitivity is common, and bacteriophage susceptibility may be a useful characteristic.
