Characterization and Recognition of Brachyspira hampsonii sp. nov., a Novel Intestinal Spirochete That Is Pathogenic to Pigs [PDF]
Journal of Clinical Microbiology, 2016 ABSTRACT Swine dysentery (SD) is a mucohemorrhagic colitis of swine classically caused by infection with the intestinal spirochete Brachyspira hyodysenteriae . Since around 2007, cases of SD have occurred in North America associated with a different strongly beta-hemolytic spirochete that has been ...

Characterization of “Brachyspira hampsonii” clades I and II isolated from commercial swine in Western Canada [PDF]
FACETS, 2016 A novel Brachyspira emerged in 2009 and has since become a production-limiting pathogen of pigs in North America. The name “Brachyspira hampsonii” has been proposed for this novel taxon.

Comparison of the Luminal and Mucosa-Associated Microbiota in the Colon of Pigs with and without Swine Dysentery [PDF]
Frontiers in Veterinary Science, 2017 Colonic contents and mucosal scrapings from pigs inoculated with Brachyspira hyodysenteriae or Brachyspira hampsonii were collected at necropsy and classified as either positive (n = 29) or negative (n = 7) for swine dysentery (SD) based upon lesions and

Fecal shedding of Brachyspira spp. on a farrow-to-finish swine farm with a clinical history of “Brachyspira hampsonii”-associated colitis [PDF]
BMC Veterinary Research, 2013 Abstract Background Brachyspira associated diarrhea is a re-emerging concern for Canadian swine producers. To identify critical control points for reducing the impact of Brachyspira on production, improved diagnostic tools and a better understanding of the on-farm epidemiology of these pathogens are ...

Confirmation that “Brachyspira hampsonii” clade I (Canadian strain 30599) causes mucohemorrhagic diarrhea and colitis in experimentally infected pigs [PDF]
BMC Veterinary Research, 2014 "Brachyspira hampsonii", discovered in North America in 2010 associated with dysentery-like illness, is an economically relevant swine pathogen resulting in decreased feed efficiency and increased morbidity, mortality and medication usage. "B. hampsonii" clade II strain 30446 has been shown to be causally associated with mucohemorrhagic diarrhea and ...

Molecular Epidemiology of Novel Pathogen “Brachyspira hampsonii” Reveals Relationships between Diverse Genetic Groups, Regions, Host Species, and Other Pathogenic and Commensal Brachyspira Species [PDF]
Journal of Clinical Microbiology, 2015 ABSTRACT Outbreaks of bloody diarrhea in swine herds in the late 2000s signaled the reemergence of an economically significant disease, swine dysentery, in the United States. Investigations confirmed the emergence of a novel spirochete in swine, provisionally designated “ Brachyspira hampsonii ,” with two ...

First isolation of “Brachyspira hampsonii” from pigs in Europe [PDF]
Veterinary Record, 2014 Infections with Brachyspira species in swine occur in most swine-rearing countries and can result in substantial economic losses. Of all swine-related Brachyspira species Infections, classical swine dysentery, caused by Brachyspira hyodysenteriae , results in the most severe clinical symptoms (eg, mucohaemorrhagic diarrhoea, weight loss, poor feed ...

First screening for Brachyspira hampsonii in Swiss pigs applying a new high resolution melting assay [PDF]
Veterinary Microbiology, 2016 A new High Resolution Melting (HRM) assay was developed for the rapid detection of Brachyspira (B.) hampsonii. B. hampsonii occurs in different European countries, however, until today it has not been encountered in Switzerland. Four B. hampsonii reference strains were used to develop the HRM assay: B.

Differential expression of hemolysin genes in weakly and strongly hemolytic Brachyspira hyodysenteriae strains [PDF]
BMC Veterinary Research, 2020 Background Swine dysentery (SD) is a diarrheal disease in fattening pigs that is caused by the strongly hemolytic species Brachyspira (B.) hyodysenteriae, B. hampsonii and B. suanatina. As weakly hemolytic Brachyspira spp. are considered less virulent or

Investigation of swine dysentery associated with "Brachyspira hampsonii" strain EB107 and comparison of diagnostic methods [PDF]
, 2018 Swine dysentery (SD) is an important cause of mucohemorrhagic diarrhea in pigs. Swine dysentery is associated with infection by Brachyspira hyodysenteriae which has historically been the only recognized strongly beta-hemolytic Brachyspira sp. However, in recent years, not all strongly beta-hemolytic isolates have been identified as B.
