Detailed explanation-1: -Not all bacteria are harmful, and some bacteria that live in your body are helpful. For instance, Lactobacillus acidophilus-a harmless bacterium that resides in your intestines-helps you digest food, destroys some disease-causing organisms and provides nutrients.
Detailed explanation-2: -Microscopic creatures-including bacteria, fungi and viruses-can make you ill. But what you may not realize is that trillions of microbes are living in and on your body right now. Most don’t harm you at all. In fact, they help you digest food, protect against infection and even maintain your reproductive health.
