## TL;DR

This paper reports the complete genome sequences of two multidrug-resistant E. coli strains from chicken meat in Vietnam, including chromosomes encoding the mcr-1.1 gene.

## Contribution

The study provides new genomic data on E. coli isolates from Vietnam carrying the mcr-1.1 gene.

## Key findings

- The genome sizes of EC332 and EC529 were approximately 5.6 and 5.1 Mbp.
- Chromosomes encoding mcr-1.1 were identified in both E. coli strains.

## Abstract

Escherichia coli strains EC332 and EC529 were isolated from chicken meat in Vietnam. The chromosomes and plasmids from both strains were sequenced using Oxford Nanopore and Illumina sequencing. The total genome sizes were approximately 5.6 and 5.1 Mbp, respectively, and chromosomes encoding mcr-1.1 were detected in both strains.
