Abstract
Whole-genome sequencing of Riemerella anatipestifer isolate RCAD0122 revealed a chromosomally located β-lactamase gene, blaRAA-1, which encoded a novel class A extended-spectrum β-lactamase (ESBL), RAA-1. RAA-1 shared ≤65% amino acid sequence identity with other characterized β-lactamases. The kinetic assay of native purified RAA-1 revealed ESBL-like hydrolysis activity. Furthermore, blaRAA-1 could be transferred to a homologous strain by natural transformation. However, an epidemiological study showed that the blaRAA-1 gene is not prevalent currently.Entities:
