Crap -- I'm homozygous G for that one too.
An appropriate response to results of a genetic stool test.
I want to point out that in every case of a carcinogenic virus or bacterial pathogen there are strains, often many strains, which do not cause cancer. This leads to questions about where the dangerous genes originate. By and large these have not been answered. While there is enormous controversy about retroviruses infecting human cells there is much less question that some do insert genes in bacteria or even other viruses. An underlying retroviral infection would explain the apparently spontaneous origin of oncogenic strains of EBV, HPV, etc. Why not H. pylori as well?
