Methanobrevibacter smithii

Methanobrevibacter smithii is not a bacterium, but an archaeon, which is a separate type of microorganism that can live in the gut. It is involved in methane production during fermentation, the process where gut microbes break down food components. Higher levels may be associated with increased methane related fermentation, gas production, bloating, slower gut movement, or changes in stool consistency. Methanobrevibacter smithii levels can help show whether methane producing microorganisms are contributing to gas related fermentation patterns in the dog’s gut profile.
