There are some types of bacteria that can be harmful to you and your family. This can cause discomfort if these bacteria enter your body through certain entry points or if you come into contact with them in other ways. Dangerous bacteria are also often called pathogenic or disease-causing bacteria because they can cause illnesses or complaints such as sore throat, abscesses or food poisoning. While some bacteria can cause disease, there are a large number of bacteria that are harmless. These bacteria are found in foods such as yogurt or in the human digestive system. Many bacteria are beneficial to us and, for example, promote digestion or physical well-being in general.
