摘要
为了探明西藏地区导致牦牛腹泻大肠杆菌的优势血清型,试验从西藏那曲、阿里、拉萨、山南、日喀则、林芝等牦牛产区发病牦牛粪便和肠黏膜中分离、鉴定出200株牦牛源大肠杆菌,并对其进行血清型鉴定。结果表明:西藏地区导致牦牛腹泻大肠杆菌的优势血清型为O78、O26、O115、O158和O14,占定型菌株的66.0%。
To investigate the dominant serotypes of Escherichia coli （ E. coli） causing yak diarrhea in Tibetan regions, 200 strains of yak E. coli were isolated and identified from feces and intestinal mucosas of sick yaks ,which were from different yak product areas, such as Tibet Naqu, All, Lasa, Shannan, Rikaze, Linzhi and so on. And then the serotype identification was performed. The results showed that the dominant sero- types of Escherichia coli causing yak diarrhea in Tibetan regions were O78, 026, O115, O158, and O14, accounting for 66.0% of the typing strains.
