Technological advances together with the continuous description of new taxa have led to frequent reclassifications in bacterial taxonomy. In this study, an extensive bibliographic revision, as well as a sequence analysis of nine housekeeping genes (cpn60, dnaJ, dnaX, gyrA, gyrB, mdh, recA, rpoB and rpoD) and a phenotypic identification of Aeromonas(More)
Two hundred and twenty-one strains representative of all Aeromonas species were characterized using the recA gene sequence, assessing its potential as a molecular marker for the genus Aeromonas. The inter-species distance values obtained demonstrated that recA has a high discriminatory power. Phylogenetic analysis, based on full-length gene nucleotide(More)
Aeromonas are autochthonous inhabitants of aquatic environments, including chlorinated and polluted waters, although they can also be isolated from a wide variety of environmental and clinical sources. They cause infections in vertebrates and invertebrates and are considered to be an emerging pathogen in humans, producing intestinal and extra-intestinal(More)
Despite the importance of diversification rates in the study of prokaryote evolution, they have not been quantitatively assessed for the majority of microorganism taxa. The investigation of evolutionary patterns in prokaryotes constitutes a challenge due to a very scarce fossil record, limited morphological differentiation and frequently complex taxonomic(More)
