About:
Bacteria are the most abundant type of all living things, and they exist widely in the natural environment or are parasitic to other organisms. Most of the bacteria are harmless or even beneficial. For example, lactic acid bacteria are widely used in the production of yogurt and beverages. However, some bacteria have serious harmful effects on the human body, such as Shigella, Salmonella, and other pathogenic bacteria.
