ABSTRACT
Strain PVT-9aT, a novel Gram-stain-negative, aerobic, non-spore-forming, motile-by-gliding and rod-shaped bacterium, was isolated from a skin lesion of Atlantic salmon (Salmo salar L.) during a tenacibaculosis outbreak that occurred in 2016 at a Chilean fish farm. Phylogenetic analysis based on 16S rRNA gene sequencing confirmed that strain PVT-9aT belonged to the genus Tenacibaculum, being related to the closest type strains Tenacibaculum haliotis KCTC 52419T (98.49â% sequence similarity), Tenacibaculum aestuariivivum JDTF-79T (97.36â%), Tenacibaculum insulae JDTF-31T (97.29â%) and Tenacibaculum ovolyticum IFO 15947T (97.15â%). The genome size of strain PVT-9aT was 2.73 Mb with a DNA G+C content 31.09 mol%. Average nucleotide identity analysis among 30 Tenacibaculum species rendered the most similar strains as follows T. haliotis KCTC 52419T (87.91â%), T. ovolyticum IFO 15947T (82.47â%), Tenacibaculum dicentrarchi 35/09T (81.08â%), Tenacibaculum finnmarkense gv finnmarkense TNO006T (80.91â%) and T. finnmarkense gv ulcerans TNO010T (80.96â%). Menaquinone MK-6 was the predominant respiratory quinone. The predominant cell fatty acids (>10â%) were iso-C15ââ0, iso-C15ââ1 G and iso-C15ââ0 3-OH. Phenotypic, chemotaxonomic and genomic data supported the assignment of strain PVT-9aT (=DSM 115155T=RGM 3472T) as representing a novel species of Tenacibaculum, for which the name Tenacibaculum bernardetii sp. nov. is proposed.
