Two clinical Aeromonas strains (A2-50T and A2-67T) recovered from the wounds of two patients in Taiwan could not be assigned to any known species of this genus based on their 16S rRNA gene sequences, which showed similarities of 99.6-99.8% to those of the type strains of Aeromonas caviae, A. trota and A. aquariorum. The rpoD phylogenetic tree allocated these strains to two novel and independent phylogenetic lines, the neighbouring species being A. caviae, the type strain of which showed 93.2% similarity (56 bp differences) to strain A2-50T and 92.2% (63 bp differences) to strain A2-67T. A multilocus phylogenetic analysis of five housekeeping genes (gyrB, rpoD, recA, dnaJ and gyrA; 3684 bp) confirmed that the two strains formed independent phylogenetic lineages within the genus. These data, together with phenotypic characterization and DNA - DNA reassociation results, revealed that these strains represent novel Aeromonas species, for which the names Aeromonas taiwanensis sp. nov. (type strain A2-50T =CECT 7403T 5LMG 24683T) and Aeromonas sanarellii sp. nov. (type strain A2-67T =CECT 7402T =LMG 24682T) are proposed.
