Brachyspira is a genus of bacteria classified within the phylum Spirochaetota

Brachyspira is a genus of bacteria classified within the phylum Spirochaetota . [2] [3] [4] Brachyspira species include pathogens in pigs, birds, dogs, and humans. B. pilosicoli colonizes millions of humans worldwide, leading to human intestinal spirochaetosis , a chronic, intermittent watery diarrhea vastly underdiagnosed [5] because of the lack of a simple diagnostic tool for clinicians. Multiplex qPCRs are promising diagnostic tools, as Brachyspira do not grow on conventional media. [6] B. pilosicoli also cause avian spirochetosis: [2] birds might be considered as the natural reservoir. B. hyodysenteriae leads to diarrheal disease in growing pigs worldwide, causing the so-called swine dysentery, typhlocolitis or porcine intestinal spirochaetosis , which contributes to major "production losses" in agrobusiness. Some species like B. innocens or B. intermedia seem to be less virulent.    https://en.wikipedia.org/wiki/Brachyspira

New Research Links Brachyspira to IBS-D New research out of the University of Gothenburg in Sweden might have found a new lead on the possible link between bacteria and IBS: a tiny, twisty troublemaker called Brachyspira. 1,2 Brachyspira is a spiral-shaped bacterium that is found in the bowels and is known to cause diarrhea in a range of animals. Only now has it been identified in humans and potentially linked to IBS-D, the type of irritable bowel syndrome that causes diarrhea. Brachyspira can survive in environments with no air, which is one reason why it has been so difficult to detect and what makes this new study so significant. Hiding in the gut Researchers have long puzzled over the connection between bacterial infections and IBS. However, they do know that a person’s risk of developing IBS increases after experiencing gastroenteritis (inflammation of the stomach and intestines, usually due to bacteria). For that reason, fecal analysis has long been used both at sma
