# Complete genomes of five Escherichia coli isolated from focal duodenal necrosis lesions of layer chickens

## TL;DR

This paper presents the complete genomes of five E. coli strains found in a chicken disease called focal duodenal necrosis.

## Contribution

The study provides the first complete genome sequences of E. coli strains associated with focal duodenal necrosis in layer chickens.

## Key findings

- Five E. coli strains were isolated from focal duodenal necrosis lesions in laying flocks.
- The complete genomes of these strains were sequenced and reported.

## Abstract

Focal duodenal necrosis (FDN) is an easily overlooked but significant disease of table-egg layers, resulting in reduced egg production. However, the etiology of FDN is poorly understood. Here, we report the complete genomes of five E. coli strains isolated from the FDN lesions of laying flocks.
