A one-year study of enteric Campylobacter infections in Singapore.

A total of 7344 inpatients with diarrhoea were investigated for Campylobacter infections in Singapore over one year. Campylobacter species were recovered from 1.2% of diarrhoeal stools; 70.3% of the 91 campylobacters were from children under 5 years of age. Further identification of these isolates showed that 89% were Campylobacter jejuni and 10.9% were C. coli, and a high level of resistance to erythromycin was observed among them. Concomitant isolation of Salmonella species or Shigella species was achieved in eight of the Campylobacter-infected patients. Campylobacter enteritis occurred throughout the year, with the highest isolation rate being recorded in September.
