Abstract: Two freshwater isolates (WB4.1-19T and WB4.4-101), sharing 99.9% 16S rRNA gene sequence similarity, were highly related to Aeromonas sobria (99.7% similarity; 6 bp differences). A phylogenetic tree derived from a multi-locus phylogenetic analysis (MLPA) of the concatenated sequences of five housekeeping genes (gyrB, rpoD, recA, dnaJ and gyrA; 3684 bp) revealed that both strains clustered as an independent phylogenetic line next to members of Aeromonas molluscorum and Aeromonas bivalvium. The DNA-DNA reassociation value between the two new isolates was 89.3 %. Strain WB4.1-19T had a DNA-DNA relatedness value of <70% with the type strains of the other species tested. Phenotypic characterization differentiated the two novel strains from all other type strains of species of the genus Aeromonas. It is concluded that the two new strains represent a novel species of the genus Aeromonas, for which the name Aeromonas rivuli sp. nov. is proposed, with the type strain WB4.1-19T (=CECT 7518T=DSM 22539T=MDC 2511 T). © 2011 IUMS.
