The phylogenetic status of Pasteurella pestis

Yersinia pestis has been characterized in terms of fingerprints of digests (pancreatic and/or T1 ribonuclease) of its 16S and 5S ribosomal RNAs. These show clearly that Y. pestis is a member of the Enterobacteriaceae and suggest that within the Family it is most closely related to Serratia and/or Proteus.
