Journal ArticleDOI
Taxonomic relationships of the [Pasteurella] haemolytica complex as evaluated by DNA-DNA hybridizations and 16S rRNA sequencing with proposal of Mannheimia haemolytica gen. nov., comb. nov., Mannheimia granulomatis comb. nov., Mannheimia glucosida sp. nov., Mannheimia ruminalis sp. nov. and Mannheimia varigena sp. nov.
TL;DR: Based on the polyphasic investigation performed a new genus Mannheimia is proposed for the trehalose-negative [P.] haemolytica complex, and two previously named species are transferred to this new genus and three new species are described.
Journal ArticleDOI
Respiratory disease in calves: microbiological investigations on trans-tracheally aspirated bronchoalveolar fluid and acute phase protein response.
Øystein Angen,John Thomsen,Lars Erik Larsen,Jesper Larsen,Branko Kokotovic,Peter M. H. Heegaard,J. M. D. Enemark +6 more
TL;DR: The results indicate that haptoglobin might be the best choice for detecting disease under field conditions and detection of P. multocida by PCR or cultivation was found to be significantly associated with the disease status of the calves.
Journal ArticleDOI
Proposal of Histophilus somni gen. nov., sp nov for the three species incertae sedis 'Haemophilus somnus', 'Haemophilus agni' and 'Histophilus ovis'
TL;DR: Results clearly support the allocation of this species to a novel genus within the family Haemophilus by sequencing the 16S rRNA and rpoB genes of strains that were investigated previously by DNA-DNA hybridization.
Journal ArticleDOI

TL;DR: In this paper , the authors show that methicillin-resistant Staphylococcus aureus appeared in hedgehogs in the pre-antibiotic era, and these lineages spread within the local hedgehog populations and between hedge-hogs and secondary hosts.
Journal ArticleDOI
Development of a PCR test for identification of Haemophilus somnus in pure and mixed cultures.
TL;DR: The present PCR test has been shown to represent a specific test for identification of H. somnus both in pure and mixed cultures and represents a quick, sensitive and reliable method for Identification of bacteria belonging to this phenotypically heterogeneous and often slow growing species.
