Why can’t we breed weaker bacteria to outcompete “superbugs”?
Well, you can't really selectively breed bacteria, they reproduce asexually, so every trait of the previous generation gets passed down to the next generation unless there is a mutation. The only way to get bacteria to get the traits we want is to somehow invoke natural selection: we allow the ba…
The Short Answer
Well, you can't really selectively breed bacteria, they reproduce asexually, so every trait of the previous generation gets passed down to the next generation unless there is a mutation. The only way to get bacteria to get the traits we want is to somehow invoke natural selection: we allow the bacteria that have the traits we want to survive, and kill the rest. If you can think of a way to selectively kill only the bacteria that are capable of causing infections, or only kill the bacteria that are resistant to antibiotics, then clear off some shelf space, because you're about to get a Nobel Prize.
