牛源大肠杆菌O157∶H7的分离鉴定
Isolation and Identification of Escherichia coli O157∶H7 from Cattle
摘要
Abstract
The objective of this study was to investigate the infection and pathogenicity of E .coli O157∶H7 from 564 fecal samples in three parts of Xinjiang,such as Akesu,Yili and Tacheng. Suspected strains were detected by biochemical and PCR after enrichment by EC broth,being cho-sen by SMAC plate and screened by MUG test.On the basis of this,the isolated strains were used in mice attack drug test.The results showed that there were two strains of E .coli O157 ∶ H7 (named Y1 66 and Y226,respectively)were isolated from the collected samples of Yili,and the de-tection rate was 0.88%.In the mice attack drug test,the mice of Y1 66 and Y226 groups were all died within 48 h.In conclusion,two strains of E .coli O157∶H7 were isolated and identified with pathogenic from samples in Yili area,and no E .coli O157∶H7 were identified in the samples from Akesu and Tacheng.关键词
