show Abstracthide AbstractWe isolated the gram-negative bacterium Leclercia adecarboxylata after screening the Swab and Send isolate library for bacteria able to tolerate 1 mg/ml of berberine, a plant flavonoid with antimicrobial properties. This strain was isolated from a swab of a horse brush. Analysis of the genome shows it contains one copy of the colistin resistance gene, mcr-9, located on an IncFII(pECLA) plasmid.
