Assessing the diversity of the virulence potential of Escherichia coli isolated from bacteremia in São Paulo, Brazil

2013

A.C.M. Santos A.C.M. Zidko A.C. Pignatari R.M. Silva

Most of the knowledge of the virulence determinants of extraintestinal pathogenic Escherichia coli (ExPEC) comes from studies with human strains causing urinary tract infections and neonatal meningitis and animal strains causing avian colibacillosis. In this research, we analyzed the phylogenetic background, the presence of 20 ExPEC virulence factors, and the intrinsic virulence potential of 74...
