||Proposal of Histophilus somni gen. nov., sp. nov. for the three species incertae sedis 'Haemophilus somnus', 'Haemophilus agni' and 'Histophilus ovis'
DNA-Directed RNA Polymerases/genetics
Molecular Sequence Data
RNA, Ribosomal, 16S/genetics
||Earlier investigations have shown that 'Haemophilus somnus', 'Haemophilus agni' and 'Histophilus ovis' represent the same species. In the present investigation, the taxonomic position of this species is explored further by sequencing the 16S rRNA and rpoB genes of strains that were investigated previously by DNA-DNA hybridization. These results clearly support the allocation of this species to a novel genus within the family PASTEURELLACEAE: The phenotypic separation of Histophilus somni gen. nov., sp. nov. from other members of the family can, for most strains, be based on capnophilia, yellowish pigmentation and indole production. However, due to phenotypic variation, the use of a species-specific PCR test based on the 16S rRNA gene is included in the species description. This is justified by the high sequence similarity of the 16S rRNA gene within the species and the fact that the highest sequence similarity to any other taxon within the family is 93.4 %. The type strain, 8025(T)=ATCC 43625(T)=CCUG 36157(T), was isolated in the USA from a bovine brain with lesions of thromboembolic meningoencephalitis.

The Culture Collections hold cell cultures, bacteria, fungi and virus strains from worldwide sources. Our scientists ensure that the identification of the cultures is correct and they remain unchanged from when they are first deposited with the Collection. Nevertheless, some of the data we provide about the cultures is supplied by the person depositing the strains and, although we have multiple checking procedures in place, we cannot always verify all their data. Please note that the Culture Collections cannot be held responsible for any inaccuracies in the data provided by the depositors.
Cultures supplied by Culture Collections are to be used as controls for microbiology testing and for research purposes only. Please view the Terms & Conditions of Supply for more information.
