What is the difference between a virus and bacteria?
There are a number of differences between a virus and bacteria, or more appropriately, viruses and bacteria, including their relative sizes, reproduction methods and resistance to medical intervention. Bacterium, the singular form of the word bacteria, is a one-celled living organism, with complete sets of both ribonucleic acid (RNA) and deoxyribonucleic acid (DNA) genetic codes. A virus is little more than a section of RNA or DNA covered by a protein shell. Bacterium, therefore, is at least a hundred times larger than a typical virus. One major difference between viruses and bacteria is the method of reproduction. Bacterium is a completely self-contained and self-reproducing unit. When the time is right, bacterium will split its DNA and RNA genetic material in two. Separate cell walls will build up around these two new bacteria, and this process will continue until thousands or millions of bacteria have formed. This is how strains of bacteria survive in almost every environment on Ear
Bacteria and viruses are both germs. Bacteria cause infections such as sore throats, ear infections, cavities and pneumonia. Viruses can cause colds, flu, chicken pox, measles and many other diseases. There are “good bacteria” and “bad bacteria” but there are almost no “good viruses.” Viruses and bacteria are very different from each other and can require different products to kill them.
