Meet doctor Cristina Gibson and her team of the center for Mike O'Brien an inflammatory researching the million British Columbia I say that number could be and that's because I've actually known about clone four collecting infant. Food everywhere if I'm asking all of Paris where there's so they still a silly to understand what kind of microbes are present. Aspects they know about the hundreds of different species that live earth. Teaming up with microbes actually is and Fairfax is seeing streets at Cole I bet that a bacteria have laughed bacillus what was on the outside. Doesn't always live on the inside. And lives on one end is annoys some on the other. Very numbers with just my doctor Gibson and her team believe the best way to test who is to first mix of moment. The testing just a portion of the Athens news doesn't tell us every. So she team that developed to process they call homogenization. Which they aren't. Offers much more reliable and represented in data. Where we get to not. I'm attempted to donate about five times in fact they tried this morning and with great difficulty I still couldn't manage to collect the samples. I tied you try for science. Fortunately for this demonstration. And old from the shot will be used. Here's where the teen introduces their own unique procedure. Essentially all you do things you take your stool put it into a peep show people. On the presence of liquid nitrogen and you write it into a fine powder it's like Atlanta had a workout Democrats yeah. Now traditional foods has been homogenized. This sample provided complete and accurate snapshot of everything in her. We're back on track ready to Pratt DNA analysis. Which means all the cellular components of broken up. Freeing the DNA. Once DNA is cleaned contaminants. It's then extracted in sequence. When the DNA of the areas microbes in the Asia still have been identified. That data is then visualize. When we're looking at my provided they'd advertising effort meaningful. Information from these mass amounts of data the red dot is snitch shot. Each green dot represented healthy individuals and new shots each group. Since doctor Gibson and her team have used the homogenization process. The convey our ally at least seen that the bacterial community in the shops who is unusual. That can be due to an infection caused by bad bacteria. But more likely having moved to Canada from Bangladesh by the years ago bishop who tells a different story. Compared to the green dots people who grew up in Canada.
