Molecular characteristics of ESBL-producing Escherichia coli isolated from chickens with colibacillosis.

ABSTRACT:

Background

Avian pathogenic Escherichia coli (APEC) causes colibacillosis, resulting in significant economic losses in the poultry industry.

Objectives

In this study, the molecular characteristics of two extended-spectrum beta-lactamase (ESBL)-producing APEC isolates were compared with previously reported ESBL-producing E. coli isolates.

Methods

The molecular characteristics of E. coli isolates and the genetic environments of the ESBL genes were investigated using whole genome sequencing.

Results

The two ESBL-producing APEC were classified into the phylogenetic groups C and B1 and ST410 and ST162, respectively. Moreover, the ESBL genes of the two isolates were harbored in different Inc plasmids. The EC1809182 strain, harboring the bla
