Draft genome sequence of CTX-M-5 variant-carrying <i>Kluyvera ascorbata</i> isolated from river water in Kumamoto, Japan

The genus <i>Kluyvera</i> is presumed to be the original source of <i>bla</i>_CTX-M genes, which encode one of the most prevalent extended-spectrum β-lactamases. We report the draft genome sequence of <i>Kluyvera ascorbata</i> strain KHSU-R5-7, a CTX-M-5 variant producing isolate obtained from Shirakawa River in Kumamoto, Japan.
