When it comes to bacteria, you might as well be talking about the witches of Oz: Are you a good microbe or a bad microbe? Good bacteria is the stuff that's in our yogurt and kombucha; it's said to do vague things like "promote gut health" and "aid in digestion." Bad bacteria is the stuff that's on toilets and kitchen sponges and airport check-in kiosks; they're the bugs that can make you sick. The way people talk about them, you'd think there must be a list somewhere defining the bacteria that are beneficial and the bacteria that are harmful. But there isn't, and there never will be. That's because there's no such thing as "good" or "bad" bacteria. What they do for you depends on context.
