I was asking doctors about E Coli, they say that if we had any anomaly about it, it would be detectable through the study of feces and urine, and if there is any alteration caused by E Coli, it would be over in a few years with our lives, then, that Ecoli class would be? An unknown? Well for sure it is difficult to say that is the cause 99.99%? I dont know.
From the studies they didn't measure the toulene from breath instead it was measured from skin. We need to get a Gas chromatography, not sure who can provide this for us.
