Ask HN: Microbiome and Diseases

I'm a layman who is very interested in the microbes that live in our gut. I want to initiate a citizen science project to relate gut microbes to known diseases. For instance, this research ties Lupus to gut microbes http://www.hcplive.com/conference-c...obiome-seems-to-have-role-in-triggering-lupus and this research ties asthma to gut microbes http://www.health24.com/Diet-and-nu...een-gut-bacteria-asthma-and-anorexia-20151105 I'm imagining to form a company like ubiome http://ubiome.com/ . My question is: What type of machinery ubiome or anyone who wants to identify gut microbes uses? I'm in Turkey and I want to find out if this test can be done here. My other question is: It is possible to identify gut microbes by traditional lab methods as in a Comprehensive Stool Test without using DNA. İs this technique inferior to DNA method? I contacted ubiome and also American Gut Project http://humanfoodproject.com/americangut/ for answers to these questions but they never answered me. I wrote to several academics and they never replied either. Thanks.
