Discovered in the gut of the brown surgeonfish, Epulopiscium actually means "guest at a banquet of fish." It's a large bacteria - the size of a hyphen in a printed text, visible to the naked eye.
It's prevalence could be as high as in 50% of the sufferers experiencing the worst symptoms, decreasing as symptoms lessen. The prevalence of this bacteria in those with strong but rarely manifested symptoms is about the same as in general population, but we never observed these bacteria in those with mild occasional symptoms or no symptoms at all.
Of course, this is not the only responsible microorganism for odors or PATM. We will be reporting more, along with what seem to help in reducing the levels.
We will also tell about bacteria "neutralizing" the odors, found in remission. Some of them are antiinflammatory, others help with digestion. Interestingly, a number of butyric acid-producing microbes also seem to help, even though butyric acid is not supposed to smell pleasant. We'll talk about it next time.
