Bacteria

Infections can occur when bacteria enter your body. Bacteria are small organisms that are found almost everywhere; in and around us, on the skin, mouth, intestines and air, water and soil. Many of them we benefit from, e.g. in our stomach and intestines to help us break down food that we eat, but there are also harmful types of bacteria that wants to enter the human body by passing our natural defense system (skin, mouth, nose, eyes, ears and abdomen).

Our immune system in the body helps to attack these foreign organisms, but if the bacteria manage to enter the body, an infection occurs. Many of these the body can take care of, but sometimes the infection is so large that the body needs external help with bactericidal drugs, so-called antibiotics.
