30,000 times is very high mag. I don't know about identifying anything at that level, because how do you know the difference between proteins and independent life forms.
Besides, we can do molecular amplifications of RNA now, which can verify foreign RNA in cells.
But, I will tell you this much; I can create conditions in a test tube, that will allow the different components of microbes to come together, and recreate the mechanisms for reproduction of the primary mature form.
This is fascinating stuff to see materialize.
I cannot do this with ordinary microbes, only in body fluid samples of those with chronic illness.
