I'm a brand new pharm tech. I am trying to learn as much as I can about the medical field. But what constitutes a Bacterial Infection? And why are Antibiotics usually prescribed for them? Why aren't Antibiotics prescribed for someone who has a virus? Thank you in advance.

PS-I love this site. I keep coming back because I love to see new content and new questions being answered. I've already purchased your Premium Package and I'm in the process of reading it. Thank you so much for writing it!

More than 99% of Bacteria is "Good" Bacteria...
by: David

Bacteria are tiny, living, one-celled organisms. More than 99% of bacteria won't harm you. Bacteria are widespread in the body. Bacteria helps you digest your food, give your body essential vitamins, and eliminate/kill cells in your body that carry disease. Healthy and "good" bacteria are actually contained in some nutritious dairy foods, such as cheese and yogurt.
However, not all bacteria are "good" bacteria. Infectious Bacteria constitutes less than 1% of all bacteria. This "bad" bacteria causes sickness and infection.

"Bad" bacteria can give off toxins when they are inside your body, which can cause you to be ill. They may also damage tissues in your body.

Enter: the Antibiotic.

How do Antibiotics work?

Well, simply put, antibiotics slow the growth of bacteria and stop them from multiplying. Or, they work to destroy the infections bacteria altogether.
