- Abstract
A Gram-stain-negative, facultatively anaerobic bacterial strain, designated 717(T), was isolated from a water sample collected from the Muga river, Girona, north-east Spain. Preliminary analysis of the 16S rRNA gene sequence showed that this strain belonged to the genus Aeromonas, the nearest species being Aeromonas veronii (99.5 % similarity, with seven different nucleotides). A polyphasic study based on a multilocus phylogenetic analysis of five housekeeping genes (gyrB, rpoD, recA, dnaJ and gyrA; 3684 bp) showed isolate 717(T) to be an independent phylogenetic line, with Aeromonas sobria, Aeromonas veronii and Aeromonas allosaccharophila as the closest neighbour species. DNA-DNA reassociation experiments and phenotypic analysis identified that strain 717(T) represents a novel species, for which the name Aeromonas fluvialis sp. nov. is proposed, with type strain 717(T) (=CECT 7401(T) =LMG 24681(T)).
