Characterization and Recognition of Brachyspira hampsonii sp. nov., a Novel Intestinal Spirochete That Is Pathogenic to Pigs [PDF]

open access: yesJournal 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 ...

Molecular Epidemiology of Novel Pathogen “Brachyspira hampsonii” Reveals Relationships between Diverse Genetic Groups, Regions, Host Species, and Other Pathogenic and Commensal Brachyspira Species [PDF]

open access: yesJournal 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 ...

Fecal shedding of Brachyspira spp. on a farrow-to-finish swine farm with a clinical history of “Brachyspira hampsonii”-associated colitis [PDF]

open access: yesBMC Veterinary Research, 2013
BackgroundBrachyspira 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

First isolation of “Brachyspira hampsonii” from pigs in Europe [PDF]

open access: yesVeterinary Record, 2014
Swine dysentery in Europe is classically attributed to Brachyspira hyodysenteriae. However, other Brachyspira species have been increasingly associated with intestinal disorders in pigs.

Differential expression of hemolysin genes in weakly and strongly hemolytic Brachyspira hyodysenteriae strains [PDF]

open access: yesBMC 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]

open access: yes, 2014
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

An optimized swine dysentery murine model to characterize shedding and clinical disease associated with "Brachyspira hampsonii" infection. [PDF]

open access: yesBMC Vet Res, 2017
BackgroundThe development of a mouse model as an in vivo pathogenicity screening tool for Brachyspira spp. has advanced the study of these economically important pathogens in recent years.

Mutational analysis of TlyA from Brachyspira hampsonii reveals two key residues conserved in pathogenic bacteria responsible for oligomerization and hemolytic activity.

open access: yesBiochimica et Biophysica Acta (BBA) - General Subjects, 2021
BACKGROUND TlyA proteins are expressed in a variety of pathogenic bacteria and possess dual hemolytic and ribosomal RNA methyltransferase functions. While the mechanism of TlyA mediated rRNA methylation is well understood, relatively little is known ...

Swine dysentery disease mechanism: Brachyspira hampsonii impairs the colonic immune and epithelial repair responses to induce lesions.

open access: yesMicrobial Pathogenesis, 2020
Swine dysentery (SD) is a global, production-limiting disease of pigs in commercial farms. It is associated with infection by Brachyspira hyodysenteriae and B.

Investigation of the impact of increased dietary insoluble fiber through the feeding of distillers dried grains with solubles (DDGS) on the incidence and severity of Brachyspira-associated colitis in pigs. [PDF]

open access: yesPLoS ONE, 2014
Diet has been implicated as a major factor impacting clinical disease expression of swine dysentery and Brachyspira hyodysenteriae colonization. However, the impact of diet on novel pathogenic strongly beta-hemolytic Brachyspira spp.
