Instead of relying on culture techniques (trying to take bacteria from our guts and grow them on an agar plate or in a tube- which they don’t like, because they only like to grow in our guts), we can now identify them using DNA/RNA sequencing of their genes. And wow! We discovered that thousands of different kinds of bacteria live in our guts, and some of them are the same …
