Phylogenomic Analysis of Extraintestinal Pathogenic Escherichia coliSequence Type 1193, an Emerging Multidrug-Resistant Clonal Group

The fluoroquinolone-resistant sequence type 1193 (ST1193) of Escherichia coli, from the ST14 clonal complex (STc14) within phylogenetic group B2, has appeared recently as an important cause of extraintestinal disease in humans. Although this emerging lineage has been characterized to some extent using conventional methods, it has not been studied extensively at the genomic level.
