Abstract

Five strains of an unusual Gram-negative, catalase-positive, oxidase-positive, coccobacillus-shaped bacterium isolated from the lungs and heart of pigs with pneumonia and pericarditis were characterized by phenotypic and molecular genetic methods. On the basis of cellular morphology and biochemical criteria, the isolates were tentatively assigned to the family , although they did not appear to correspond to any recognized genus or species. Comparative 16S rRNA gene sequencing showed that the five unidentified strains were phylogenetically highly related to each other and represent a hitherto unknown subline within the family . On the basis of both phenotypic and phylogenetic evidence, it is proposed that the unknown isolates from pigs be classified as a novel genus and species within the family , for which the name gen. nov., sp. nov. is proposed. The type strain of is 1258/02 (=CCUG 47806=CECT 5685).
