Brachyspira hampsonii

Brachyspira hampsonii is a gram-negative, spiral-shaped microbe that thrives in mesophilic temperatures, classified as a chemoheterotroph, and can inhabit various body sites in multiple species, including the intestinal tracts of pigs, birds, and humans. As an obligate anaerobe, it requires the absence of oxygen to survive and grow. The gram-negative characteristic indicates that the microbe's cell wall contains a thin peptidoglycan layer, making it more resistant to certain antibiotics. Its spiral shape allows it to move and colonize efficiently in its environment. Being a mesophile, Brachyspira hampsonii grows best in temperatures between 20-40°C, which is typical for many intestinal microbes. As a chemoheterotroph, it relies on organic compounds for energy and carbon sources, breaking down complex molecules to sustain its growth. This microbe can be found in various body sites, including the gastrointestinal tracts of different hosts, where it can cause disease or coexist as a commensal. The obligate anaerobic nature of Brachyspira hampsonii makes it well-suited to the low-oxygen environments found in the intestines. Brachyspira hampsonii has been associated with colonic spasms and diarrhea in pigs, and its ability to infect multiple species has raised concerns about its potential impact on animal and human health. The microbe's unique characteristics have led researchers to investigate its role in the development of intestinal diseases, and studies have shown that it can outcompete other microbes in the gut, potentially leading to an imbalance in the intestinal microbiota.
