Phylogeny and species identification of the family Enterobacteriaceae based on dnaJ sequences

Phylogenetic relations within the family Enterobacteriaceae were analyzed using partial dnaJ sequences of 165 strains belonging to 93 species from 27 enterobacterial genera. The dnaJ phylogeny was in relative agreement with that constructed by 16S rDNA sequences, but more monophyletic groups were obtained from the dnaJ tree than from the 16S rDNA tree. The degree of divergence of the dnaJ gene was approximately 6 times greater than that of 16S...
