This is pretty disturbing for sure. Trichomoniasis fortunately die very quickly in unfavorable conditions (when under a microscope they will die in minutes and are actually hard to visualize in time).
A good public health solution is to have wrapping around the seat of the toilet that can be switched after each user. I actually saw these in the Chicago airport awhile ago.
Nice research!
It's not so much a health issue (it is pretty gross though), but perhaps could be a useful tool for getting a feel for what strains of bacteria are prevalent in a given population. Could help in allowing for faster identification of the best possible treatments. More info for doctors is never a bad thing.
For sure! We may know a lot about health but there are way too many studies to be fully up-to-date!
