Abstract

During the present investigation evidence was obtained to indicate that porcine Pasteurella haemolytica–like strains were sufficiently different from P. haemolytica sensu stricto to constitute a new taxon within the family Pasteurellaceae Pohl 1981. Thirteen strains formed a homogenous group tentatively designated taxon 15. The final taxonomical position of taxon 15, however, has to await further taxonomical investigations, including determinations of mol % G+C in DNA and DNA: DNA hybridizations. A species name has not been suggested, for the same reasons.
