Origin and development of two <i>Escherichia coli</i> clones vertically transferred in broiler production.

ABSTRACT: Investigation of clonal development of dominant persistent clones of avian pathogenic Escherichia coli (APEC) is important to understand their evolution and to gain knowledge to improve their control in poultry production. Whole-genomic sequencing, including hybrid assembled genomes of short and long reads, was used to analyse clonal persistence and evolution of APEC. Two vertically transferred E. coli clones, represented by ten isolates from sequence type (ST) 95-PFGE type 65 and eight isolates from ST131-PFGE type 47, were selected to identify genomic variations. The isolates had been sampled in broiler production during a period of 9 months in a previous study. The main differences among strains within each clone were related to plasmids, transposases, incomplete phage ele
