What is bacteria?
Bacteria are everywhere. They are on everything we see and touch, in the air we breathe, and even in the water we drink. In fact, right now, the bacterial cells on (and in) your body actually outnumber your own cells. Much of this bacteria is beneficial, helping us to digest our food, fight off sickness, and even keep our breath fresh. "Good bacteria" also helps to displace, or crowd out, the bad bacteria, which when found in drinking water can cause symptoms like nausea, diarrhea, cramps, and headaches. that can cause things like pneumonia, syphilis, cholera, and infections like Strep and Staph.
