Living organisms serve as a habitat for parasitic bacteria. Parasitism is when one organism (parasite) lives in another living organism, using it as a food environment. There are ways in which parasites enter the body of the “host”: 1) A small parasite settles near the house or near a large organism (animal, bird, etc.). And then over time it goes to his body. 2) The predator attacks the prey more than him, and unable to defeat it can be eaten by itself. In this way, once inside the “host” it begins to adapt there and becomes a parasite. 3) Accidental hit, when small pests enter a large animal, through food, etc. surviving begin to parasitize.
