Researchers in the UK (affiliated with ZOE, if anyone's familiar) have discovered that regular coffee consumption is associated with the presence of this intestinal bacteria. It was recently identified, and not a whole lot is known about it but it is a butyrate producer, so perhaps that contributes to coffee's benefits in PD?

And here's the study in Nature; nature.com/articles/s41564-...
