sp. nov., isolated from aquaria of ornamental fish Free

Abstract

During a survey to determine the prevalence of strains in water and skin of imported ornamental fish, 48 strains presumptively identified as were isolated but they could not be identified as members of any previously described species. These strains were subjected to a polyphasic approach including phylogenetic analysis derived from , and 16S rRNA gene sequencing, DNA–DNA hybridization, MALDI-TOF MS analysis, genotyping by RAPD and extensive biochemical and antibiotic susceptibility tests in order to determine their taxonomic position. Based on the results of the phylogenetic analyses and DNA–DNA hybridization data, we describe a novel species of the genus , for which the name sp. nov. is proposed, with strain MDC47 (=DSM 18362 =CECT 7289) as the type strain. This is the first species description based on isolations from ornamental fish.
