Matt Kelly explains how antibiotics kill beneficial bacteria, letting biofilm-forming microbes overgrow and create protective barriers that allow opportunistic infections to take hold. When good bacteria disappear, bad ones move in and build fortified communities.
So let's say you get a whole bunch of antibiotics or you get chemotherapy or you're just really sick for a long time. What will happen is that the bugs in the small quantities will start to overgrow and they'll take the place of your good bacteria that you killed with, you know, a drug or being sick a long time or whatever. So then if you have a higher and higher quantity of a biofilm-creating bacteria, for example, other things can make biofilm. Then what'll happen is they start to make biofilms, 'cause that's what they do. They're trying to protect themselves, 'cause now they're taking over the neighborhood. And so what goes on then is they're building these things, and then other, you can call them inappropriate or pathogenic organisms, whether they're fungal or viral or bacterial or whatever, can get in there. And like I say, they all work and live as a hive.
