## TL;DR

A type of Vibrio cholerae found in edible fish in Vietnam was found to carry antibiotic resistance genes on a large plasmid.

## Contribution

The discovery of blaCTX-M-55 and blaTEM-1 on an IncA/C plasmid in non-O1 V. cholerae from fish.

## Key findings

- Non-O1 Vibrio cholerae isolates from edible fish in Vietnam were found to produce extended-spectrum β-lactamases.
- A plasmid of approximately 183-kb was identified, encoding blaCTX-M-55 and blaTEM-1 genes.
- The plasmid belongs to the IncA/C incompatibility group.

## Abstract

Extended-spectrum β-lactamase-producing non-O1 Vibrio cholerae was isolated from edible Mastacembelus sp. in Vietnam. The genome sequence was sequenced using DNBSEQ-G400 and MinION Mk1b. A plasmid of approximately 183-kb encoding blaCTX-M-55 and blaTEM-1 was detected.
