       | possibly hadn't been seen before.

           | even other bacteria such as one species of large rod bacteria
           | that has a different species of little rod bacteria that live
           | on it, biofilms, etc.

             | I know, but I would expect doctors would, by know, not be
             | so frequently surprised by things lurking in their own
             | bodies.

             | Not that long ago a never before observed structure every
             | human always had was discovered:

             | Doctors don't ask about this. People still take Prilosec,
             | and it's acknowledged that it causes cancer. You get what
             | you give: confirmation bias.
             | 
             | Edit: The essential problem is that ranitidine isn't shelf-
             | stable. This could explain some problems with other
             | theraputics which we won't name to avoid downvoting /
             | politics.

       | It advances research, but personalized microbiome research seems
