A member asked:
Are bacterial infections harmful and are they contagious?
A doctor has provided 1 answer
Yes/yes: We often have bacteria in/on our bodies in harmony.The process is labeled colonization and can be useful. You clot your blood with the help of gut bacteria's effect on vitamins. We usually reserve the term infection to note a harmful process. Bacteria are acquired from the environment, whether that be from persons,animals or objects where they live.The degree of contagiousness varies.
