## TL;DR

This paper presents the full genome of a Corynebacterium ulcerans strain from a leg ulcer, including two new toxin gene variants.

## Contribution

The study identifies and reports two novel toxin gene alleles in a C. ulcerans clinical isolate.

## Key findings

- The complete genome sequence of a C. ulcerans clinical isolate was determined.
- Two novel and distinct toxin gene alleles were identified in the isolate.

## Abstract
