Polyphasic analysis was done on 24 strains of Bisgaard taxon 16 from five European countries and mainly isolated from dogs and human dog-bite wounds. The isolates represented a phenotypically and genetically homogenous group within the family Pasteurellaceae. Their phenotypic profile was similar to members of the genus Pasteurella. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry clearly identified taxon 16 and separated it from all other genera of Pasteurellaceae showing a characteristic peak combination. Taxon 16 can be further separated and identified by a RecN protein signature sequence detectable by a specific PCR. In all phylogenetic analyses based on 16S rRNA, rpoB, infB and recN genes, taxon 16 formed a monophyletic branch with intraspecies sequence similarity of at least 99.1, 90.8, 96.8 and 97.2 %, respectively. Taxon 16 showed closest genetic relationship with Bibersteinia trehalosi as to the 16S rRNA gene (95.9 %), the rpoB (89.8 %) and the recN (74.4 %), and with Actinobacillus lignieresii for infB (84.9 %). Predicted genome similarity values based on the recN gene sequences between taxon 16 isolates and the type strains of known genera of Pasteurellaceae were below the genus level. Major whole cell fatty acids for the strain HPA 21(T) are C14:0, C16:0, C18:0 and C16:1 ω7c/C15:0 iso 2OH. Major respiratory quinones are menaquinone-8, ubiquinone-8 and demethylmenaquinone-8. We propose to classify these organisms as a novel genus and species within the family of Pasteurellaceae named Frederiksenia canicola gen. nov., sp. nov. The type strain is HPA 21(T) (= CCUG 62410(T) = DSM 25797(T)).

To reinvestigate the taxonomy of [Actinobacillus] muris, 474 strains mainly from mice and rats were characterized by phenotype and 130 strains selected for genotypic characterization by 16S rRNA and partial rpoB gene sequencing. The type strain was further investigated by whole genome sequencing. Phylogenetic analysis of the DNA sequences showed one monophyletic group with intra group similarities of 96.7 % and 97.2 % for 16S rRNA and rpoB genes, respectively. The lowest 16S rRNA similarity to the closest related valid named taxon outside the group was 95.9 % to the type strain of [Pasteurella] pneumotropica. The closest related taxon based on rpoB sequence comparison was 'Haemophilus influenzae-murium' with 88.4 %. A new genus, Muribacter is proposed based on a distinct phylogenetic position based on 16S rRNA and rpoB gene sequence comparisons with major divergence to the existing genera of Pasteurellaceae. The new genus includes the characteristics of [Actinobacillus] muris with the emendation that acid formation from (-)-D-mannitol is variable as well the hydrolysis of esculin while the α-glucosidase test is positive. There is no requirement for exogenously supplied nicotinamide adenine dinucleotide (V factor) for the majority of strains investigated, however, one strain was found positive. The major fatty acids of the type strain of Muribacter muris were C 14:0, C 14:0 3OH/C 16:1 ISOI, C 16:1 ω7c and C 16:0 which is in line with most genera of Pasteurellaceae. The type strain of Muribacter muris is CCUG 16938T ( = NCTC 12432T = ATCC 49577T).
