Whole genome sequencing of an ExPEC that caused fatal pneumonia at a pig farm in Changchun, China.

We isolated the ExPEC (SLPE) from swine lungs in China, performed the whole genome sequencing and compared the sequence with other Escherichia coli (E. coli). The comparative genomic analysis revealed several genes including several virulence factors that are ExPEC strain-specific, such as fimbrial adhesins (papG II), ireA, pgtP, hlyF, the pix gene cluster and fecR for their further study. We found a CPS in the SLPE strain genomes for the first time, and this CPS is closely related to the CPS from Klebsiella pneumoniae.
