Some harmful microbes are responsible for infection and acute disease, while "other bacteria, the more intelligent ones, have taken the evolutionary route of shaping their environment by positively interacting with the host immune system to promote health, which gives them an improved place to live; it's like creating bacterial nirvana," says one of the researchers.
