Background and purpose: 

Escherichia coli is an important foodborne zoonotic pathogen. A total of 285 strains of E. coli were isolated from the production and supply chain of pork in Hubei, China and characterized. Their phylogroups (A, B1, B2, and D) and virulence genes of public health importance become more and more diverse along the production and supply chain. 


Key words:

extraintestinal pathogenic E. coli, phylogenetic grouping, production, supply chain, virulence genes
