[Evaluation of 4 culture methods of Yersinia enterocolitica].

OBJECTIVE: To establish a highly efficient culture method for detecting Yersinia enterocolitica in stool samples from diarrheic patients.

METHODS: Stool samples collected from 200 diarrheic patients were detected with a modified and 3 conventional methods, and the positivity rates of the bacterium were compared statistically.

RESULTS: With the modified method, 18 positive samples for Yersinia enterocolitica were detected from 200 stool samples, while with the 3 conventional methods, only 3, 5, and 8 positive samples were identified, respectively. Statistical analysis with McNemer test suggested significant difference in the positive detection rate between the modified and the 3 conventional methods.

CONCLUSION: The modified method for Yersinia enterocolitica detection has much higher sensitivity than the 3 conventional methods, and can be applied in clinical detection.
