Failure to isolate Yersinia enterocolitica from patients with diarrhoea in Singapore

To determine the presence of Yersinia enterocolitica in Singapore, an attempt was made to isolate this organism from the stool samples of 6,619 patients with diarrhoea. No Y. enterocolitica was detected. The results suggest that Y. enterocolitica is not an important bacterial pathogen causing diarrhoeal disease in this region.
