Abstract:
The Escherichia coli (E.coli) strain from intestinal tract of died newborn swine was isolated and cultured.Preliminary identification of the isolated strain was conducted by conventional biochemical tests,and the molecular biology detections of toxicity gene and typing gene were completed by multi-PCR.Stable toxin and heat-labile enterotoxin genes of E.coli were detected from the isolated strain.By amplifying and sequencing bacterial 16s rDNA and fliC gene,the isolated strain was identified as H10 by Blast analysis.The homology of strain H10 was 99% with bacterial 16s rDNA gene and 98% with fliC gene.
