Prions, bacteria, and viruses are all kind of blurred together and known generically as the same thing. All of them infect your body in some way, whether it is a viral infection or a bacterial infection. Most diseases can be treated and/or prevented by the aid of vaccines and antibiotics. Bacteria contain both DNA and RNA. These nucleic acids float freely in the cytoplasm of the cell. Bacterium reproduces asexually by using bacterial fission. Fission is kind of like mitosis, the cells insides are copied and the cell splits into two, then four, etc. Some bacteria is beneficial for our bodies, the bacteria that is unwanted can be cured by using antibiotics. Bacterium infect through parasitism, mutualism, or commensalism. Viruses cannot contain both DNA and RNA; it has either one or the other. They reproduce sexually by invading a host cell; the virus then releases its nucleic acid. The released acid merges with the healthy cell and makes it become infected. Viruses are not beneficial in any way, and they are hard to cure. Vaccines can prevent the virus from spreading, but not much else can be done. Prions don’t contain DNA or RNA. Prions are made of misshapen proteins, the protein then merges with the rest of the cell incognito, and after this has happened it begins to take control of the body. Infections caused by prions aren’t the most popular type, but they still happen. All of the infections your body is exposed to can be harmful, whether it’s through bacterium, viruses, or prions.
