Bacteria are very small living organisms made of only one cell . They are present just about everywhere : the air, the soil, and the skin, for example. Many of them are microbes that cause diseases (rhinitis, listeriosis, and others), but others are very helpful to humans. For example, bacteria in the intestine help digestion and we often use bacteria to make food products (yoghurt, sauerkraut, and others).
