First molecular detection of Brachyspira hampsonii on pig farms in Poland [PDF]
Acta Veterinaria HungaricaAbstractNowadays, the three strongly beta-haemolytic spirochaetes, Brachyspira hyodysenteriae, Brachyspira suanatina and Brachyspira hampsonii are thought to be causative agents of swine dysentery, an economically devastating disease of grow-finish pigs characterised by severe mucohaemorrhagic diarrhoea. 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]
PLoS 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.

In vitro attenuation of a virulent swine isolate of Brachyspira hampsonii [PDF]
Pathogens and Disease, 2017 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.

An optimized swine dysentery murine model to characterize shedding and clinical disease associated with "Brachyspira hampsonii" infection. [PDF]
BMC Vet Res, 2017 The 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. However, none of the murine models published to date have been used to characterize the clinical signs of disease in mice, instead focusing on pathology following oral ...

Brachyspira Species Avidity to Colonic Mucins from Pigs with and without Brachyspira hyodysenteriae Infection Is Species Specific and Varies between Strains. [PDF]
Infect Immun, 2021 Brachyspira hyodysenteriae is commonly associated with swine dysentery (SD), a disease that has an economic impact on the swine industry. B. hyodysenteriae infection results in changes to the colonic mucus niche with massive mucus induction, which ...

Xenotransplantation, Volume 30, Issue 5, September/October 2023., 2023 Abstract Xenotransplantation has the potential to address shortages of organs available for clinical transplantation, but concerns exist regarding potential risks posed by porcine microorganisms and parasites (MP) to the health of human recipients. In this study, a risk‐based framework was developed, and expert opinion was elicited to evaluate porcine ...

Phenotypic and molecular characterization of a novel strongly hemolytic Brachyspira species, provisionally designated “ Brachyspira hampsonii ” [PDF]
Journal of Veterinary Diagnostic Investigation, 2012 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.

Fluorescent in situ hybridization for detection of “ Brachyspira hampsonii ” in porcine colonic tissues [PDF]
Journal of Veterinary Diagnostic Investigation, 2013 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.

Cross-reactions in specific Brachyspira spp. PCR assays caused by “ Brachyspira hampsonii ” isolates [PDF]
Journal of Veterinary Diagnostic Investigation, 2016 An emerging novel spirochete in swine, provisionally designated “ Brachyspira hampsonii,” has been detected worldwide. It has been associated with swine dysentery and cannot be differentiated from B. hyodysenteriae, the classical etiologic agent of this disease, using standard phenotypic methods. We evaluated cross-reactions of “ B. hampsonii” isolates

Comparison of culture, polymerase chain reaction, and fluorescent in situ hybridization for detection of Brachyspira hyodysenteriae and “ Brachyspira hampsonii ” in pig feces [PDF]
Journal of Veterinary Diagnostic Investigation, 2014 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 ...
