Two gram-negative, catalase- and oxidase-positive, bacillus-shaped bacterial strains were isolated from the semen of two rams. 16S rRNA gene sequencing demonstrated that both isolates represented a distinct subline within the family Pasteurellaceae with <95% sequence similarity to any recognized member of this family. Sequencing of rpoB and infB genes confirmed this finding with the semen isolates representing a new sub-line within the family Pasteurellaceae. The main cell fatty acids of strain DICM-00342(T) were C-14:0, C-16:0, C-18:1 omega 7c and summed feature 3 (C-16:1 omega 7c/iso-C-15:0 2OH). Ubiquinone Q-8 was the major quinone and 1,3-diaminopropane was the predominat polyamine. Major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. The new genus can be phenotypically distinguished from currently described genera of this family based on physiological traits and a combination of signature amino acids in the RpoB protein sequence. On the basis of these results we describe a new genus and species for which we propose the name of Seminibacterium arietis gen. nov., sp. nov. (DICM11-00342(T) = CCUG 61707(T) = CECT 8033(T)).
