Because some of the bacteria in the human body fights off diseases, and some cause them. for example, in your antibodies, you have a bacteria that fights certain sickness. Also, a type of bacteria helps you digest food. That's why it's not safe to drink hand sanitizer.
No. Bacteria is part of our existence. We need bacteria in our daily lives. Bacteria are both harmful and useful to the environment and animals, including humans.
Bacteria can be good or bad for you, depending on what bacteria it is.
Bacteria is good and bad for you.
bad bacteria can get you sick and ruin your immune system....and good bacteria helps protect you from the bad bacteria trying to ruin your immune system!!!

No such thing as "bad bacteria" and "good bacteria" because they are all one and the same (though not literally) and can be affected by the same thing if the "bad" bacteria is targeted. A rod-shaped bacterium can be any bacterial species, "good" or "bad."
bacteria, good mushrooms have good bacteria,bad mushrooms have bad bacteria.simple as that
Good bacteria will not harm you if you consume it, it is also used in the production of cheese, alchohol and bread. Good bacteria is aslo used to break down matter in the enviroment.
