Gut Bacteria Part 2

Part 2 of an interview with a microbiologist regarding Gut Bacteria.  The first half of this video is a repeat of the techniques used to get the DNA from the different gut bacterias(some of which was shown in Video 1, and is rather technical, but once you understand the idea and concept it makes a ton of sense), and how to separate this bacteria from the other matter that was collected in the human’s stool samples that were used for this test.

Remember, the test was to see if human gut bacteria is changed after people take antibiotics, so Les had to determine what bacteria was in the gut before, during, and after the study.
