Bacteria are microbes that are invisible to the naked eye because of their size. You can observe them under a microscope.

There are two types of bacteria: beneficial (or good) bacteria and harmful (or bad) bacteria. The beneficial ones stay in the body and help in digestion, make some vitamins, and fights off infection. The harmful bacteria are found in the environment and can enter your body when you come in contact with them, causing diseases when your immunity is weak. These cause infections and hence are also referred to as infectious bacteria.
