Negative bacteria values.

Bacteria are living organisms (most often single-celled) that appeared a very, very long time ago. They are an important link in almost all processes occurring on the planet. There is nothing where they are not. Some bacteria are beneficial, while others are the opposite. Negative and most dangerous are those that cause infectious diseases. Some species are capable of producing toxins that are powerful poison to the body. There are bacteria that can spoil food, as a result of which they should not be eaten, as you can get serious poisoning.
