Abstract
The phylogenetic relationships of the type strains of 38 species from 15 ge nera of the family Enterobacteriaceae were investigated by comparative 16S rDNA analysis. Several sequences of strains from the genera Citrobacter, Er winia, Pantoea, Proteus, Rahnella and Serratia, analysed in this study, hav e been analysed previously. However, as the sequences of this study differ slightly from the published ones, they were included in the analysis. Of th e 23 enterobacterial genera included in an overview dendrogram of relatedne ss, members of the genera Xenorhabdus, Photorhabdus, Proteus and Plesiomona s were used as a root. The other genera formed two groups which could be se parated, although not exclusively, by signature nucleotides at positions 59 0-649 and 600-638. Group A contains species of Brenneria, Buttiauxella, Cit robacter, Escherichia, Erwinia, Klebsiella, Pantoea, Pectobacterium and Sal monella. All seven type strains of Buttiauxella share 16S rDNA similarities greater than 99%. Group B embraces two phylogenetically separate Serratia clusters, a lineage containing Yersinia species, Rahnella aquatica, Ewingel la americana, and also the highly related pair Hafnia alvei and Obesumbacte rium proteus.
