These are single-cell organisms that can multiply rapidly on their own. Most are harmless or beneficial but some can cause infectious diseases such as strep throat or tuberculosis.
What are bacteria?
This is the process of gathering data and making assumptions to estimate short- and long-term harmful effects on human health or the environment from exposure to hazards associated with the use of a particular product or technology
