Infection of porcine colon explants with “Brachyspira hampsonii” leads to increased epithelial necrosis and catarrhal exudate [PDF]
Mucohemorrhagic diarrhea in pigs caused by Brachyspira spp. has a global distribution, and an economic impact on affected farms due to poor performance of animals. Demonstrations that "Brachyspira hampsonii" is pathogenic have been achieved using in vivo animal models, but a critical knowledge gap exists regarding the pathogenic mechanisms employed by ...

In vitro attenuation of a virulent swine isolate of Brachyspira hampsonii [PDF]
Brachyspira hampsonii causes dysentery-like disease in infected pigs. Serial passage of a virulent swine isolate (P13) one-hundred times in laboratory culture medium was conducted to produce an attenuated strain, and to identify genomic determinants of virulence through comparison of genome sequences of the original and passaged strains.

Comparison of culture, polymerase chain reaction, and fluorescent in situ hybridization for detection of Brachyspira hyodysenteriae and “Brachyspira hampsonii” in pig feces [PDF]
Swine dysentery is characterized by mucohemorrhagic diarrhea and can occur following infection by Brachyspira hyodysenteriae or “ Brachyspira hampsonii ”. A definitive diagnosis is often based on the isolation of strongly beta-hemolytic spirochetes from selective culture or by the application of species-specific polymerase chain reaction (PCR) assays ...

Fluorescent in situ hybridization for detection of “Brachyspira hampsonii” in porcine colonic tissues [PDF]
Swine dysentery is classically associated with infection by the strongly beta-hemolytic Brachyspira hyodysenteriae; however, the proposed novel species “ Brachyspira hampsonii” has also been isolated from clinical cases of dysentery in the United States and Canada. Microbial culture is highly sensitive for detecting Brachyspira in clinical samples but

Swine dysentery is classically associated with infection by Brachyspira hyodysenteriae, the only current officially recognized Brachyspira sp. that consistently imparts strong beta-hemolysis on blood agar. Recently, several strongly beta-hemolytic Brachyspira have been isolated from swine with clinical dysentery that are not identified as B ...

Phenotypic and molecular characterization of a novel strongly hemolytic Brachyspira species, provisionally designated “Brachyspira hampsonii” [PDF]
Since 2007, outbreaks of severe bloody diarrhea and hemorrhagic colitis have been reported in the United States and Canada. Though the primary causative agent of swine dysentery is Brachyspira hyodysenteriae, which is strongly hemolytic, the current report describes the isolation of a novel strongly hemolytic Brachyspira sp. This novel Brachyspira sp.

"Brachyspira hampsonii" clade I isolated from Belgian pigs imported to Germany.
Veterinary Microbiology, 2014This report describes the detection of "Brachyspira (B.) hampsonii" clade I in Belgian pigs imported to Germany. Two of seventeen pigs from one herd were reported positive for Brachyspira hyodysenteriae by culture in a Belgian diagnostic laboratory, but negative for this Brachyspira species by specific PCR.

'Brachyspira hampsonii' is a recently proposed new species within the Brachyspira genus, which produces a dysentery-like disease in pigs. This study aims at investigating whether a 'B. hampsonii' isolate recovered from a migrating waterfowl was capable of colonizing pig intestines, inducing clinical signs of dysentery and being transmitted among pigs ...
