Not an expert but there are studies going on. The current process seems to be roughly:

>There are two labs, O'Toole explains, that processed my sample. The first was the wet lab, where, through various molecular assaults, DNA was extracted, 95% of which was bacterial. This was then sent to an external company to be sequenced – there were over 30,000 sequences – and then a huge file of data was crunched by what O'Toole called "a bunch of computer nerds who sit around all day generating stats" in the institute's data lab. (https://www.theguardian.com/science/2014/feb/11/gut-biology-...)

so you get a lot of genetic data mixed up from a lot of strains and it's probably hard to make sense of.
