| Abstract: | A strain of bacterium was isolated from the liver of dead primiparity guinea fowl in Guangdong.The culture characteristics,chemical characteristics,pathogenic and serotype detection showed that the isolated strain was Escherichia coli,16S rRNA sequencing result supported this conclusion.The results demonstrated that the strain was pathogenic Escherichia coli which did not ferment lactose. |
