IntroductionSwine dysentery (SD) typically manifests as a severe mucohemorrhagic colitis arising from infection of the caecum and colon of grower-finisher pigs with the anaerobic intestinal spirochete Brachyspira hyodysenteriae [1]. SD can severely depress feed conversion efficiency, may require considerable antimicrobial use for its control, and represents an animal welfare issue. Strains of B. h ...

IntroductionThe genus Brachyspira includes seven officially named and several unofficially named species of anaerobic spirochaetes that colonize the large intestine of mammals and birds [1]. The three most commonly reported pathogenic species are Brachyspira hyodysenteriae, the agent of swine dysentery, Brachyspira intermedia, a pathogen mainly of adult chickens, and Brachyspira pilosicoli, the ca ...

IntroductionThe Intestinal spirochete Brachyspira hyodysenteriae is the etiological agent of swine dysentery (SD)—a severe mucohemorrhagic colitis of pigs [1] Despite the economic importance of SD and the need to control the disease, knowledge is lacking about metabolic and other adaptations that have allowed the spirochete to successfully colonize the complex and potentially hostile environ ...

IntroductionBacteria of the genus Brachyspira are anaerobic intestinal spirochaetes that can cause diarrhoea and mortality in pigs and other species. This genus comprises seven officially named species and several provisionally named species. Six of these can be found in the porcine large intestine, and currently three are considered to be enteropathogenic to the pig [1]. The most important is Bra ...

IntroductionThe intestinal spirochaete Brachyspira hyodysenteriae is the classical causative agent of swine dysentery (SD), a disease typically associated with severe colitis and bloody mucoid diarrhoea mainly seen in grower and finisher pigs [1]. Two related species, Brachyspira suanatina and “Brachyspira hampsonii”, also have been shown to occur in pigs and to cause SD on occasion [2 ...

The name “Brachyspiral colitis” recently was introduced into the literature on swine diseases to describe the situation where colitis, diarrhea and/or dysentery occur in pigs infected with one or more pathogenic Brachyspira species (Hampson, 2012). The term was created to emphasise an increasing understanding of the diversity of anaerobic intestinal spirochetes in the genus Brachyspira ...
