[Enterobacterial taxonomy: Erwinia carotovora and Yersinia enterocolitica].

The immunotyping of the intracellular protein complex in enterobacteria has allowed to reveal that the intracellular proteins of E. carotovora and Y. enterocolitica possess an antigenic profile characteristics of bacteria belonging to the family Enterobacteriaceae. E. carotovora are similar to the main group of enterobacteria (Escherichia, Shigella, Salmonella, Enterobacter, Klebsiella, Citrobacter, Arizona) in the degree of the antigenic homology of their intracellular protein complex. Y. enterocolitica considerably differ from other enterobacteria, forming an independent immunotype of the family Enterobacteriaceae.
