A total of 29 strains mainly from guinea pigs were investigated by a polyphasic approach that included previously published data. The strains were classified as Bisgaard taxa 5 and 7 by comparison of phenotypic characteristics and the strains showed typical cultural characteristics for members of family Pasteurellaceae and the strains formed two monophyletic groups based on 16S rRNA gene sequence comparison. Partial rpoB sequence analysis as well as published data on DNA-DNA hybridization showed high genotypic relationships within both groups. A new genus with one species, Caviibacterium pharyngocola gen. nov., sp. nov., is proposed to accommodate members of taxon 5 of Bisgaard, whereas members of taxon 7 are proposed as Conservatibacter flavescens gen. nov., sp. nov. The two genera are clearly separated by phenotype from each other and from existing genera of the family Pasteurellaceae. The type strain of Caviibacterium pharyngocola is 7.3T (=CCUG 16493T=DSM 105478T) and the type strain of Conservatibacter flavescens is 7.4T (=CCUG 24852T=DSM 105479T=HIM 794-7T), both were isolated from the pharynx of guinea pigs.
