4种小肠结肠炎耶尔森菌培养方法的研究与评价

目的 建立一种高效的临床培养方法检测腹泻病人粪便中的小肠结肠炎耶尔森氏菌.方法 用改良培养方法和3种传统培养方法同时检测200份腹泻病人粪便,以比较其检出率.结果 改良培养方法(YSE-CIN))从 200份腹泻粪便中检测到18份含有小肠结肠炎耶尔森氏菌的样本,而另外3种方法(PBSS-SS法、PAE-NYE法、PAE-DYS法)的阳性例数分别为3、5、8.经McNemer检验,改良方法与其他3种方法的检出率具有显著性差异.结论 改良方法比其他3种方法的检出率更高,可应用于临床.

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 conventiona methods, and can be applied in clinical detection.
