Penicillin is used to kill bacteria that cause damage. It kills the bacteria which can cause ear damage.
The two microscopic organisms that cause disease are bacteria and viruses. Bacteria are single-celled microorganisms that can multiply and cause infections in the body, while viruses are smaller infectious agents that can only replicate inside the cells of living organisms.
Both viruses and bacteria can cause diseases, reproduce, infect something, contain genetic material, and are single celled.
pathogen
by spreading bacteria
They all can be, but not all bacteria ec cause disease and some are symbiotes.
