Viruses and bacteria are two words that are often mentioned in daily life. They will not only cause great harm to the patient's physical health, but also seriously affect their normal life and work. Therefore, it is particularly important to have a certain understanding of viruses and bacteria and to better distinguish between the two. Many people don’t know which one will get better faster, viruses or bacteria. There is no accurate answer to this question, which will vary depending on the types of viruses and bacteria. 1. Understand their basic differences. Viruses and bacteria differ significantly in size, origin, and effects on the body. Viruses are the smallest and simplest living organisms, 10 to 100 times smaller than bacteria. Bacteria are single-celled organisms that can live inside or outside of other cells. It can survive even without a host. However, viruses are intracellular organisms that need to invade other cells and survive inside them. Viruses change the genetic material of their hosts, thereby using the hosts to produce large numbers of viruses. Antibiotics cannot kill viruses, they can only kill bacteria, but antibiotics are also powerless against bacteria that are immune to antibiotics. It is the abuse of antibiotics that leads to the existence of bacteria immune to antibiotics, which greatly weakens the ability of antibiotics to kill deadly bacteria. Gram-negative bacteria are highly immune to antibiotics, but there are still antibiotics that can kill them. 2. Bacteria and viruses also differ in their proliferation. Whether it is an animal or plant cell, a virus must find a host cell in order to reproduce, but most bacteria can live alone without relying on any host. Bacteria have a complete set of equipment (organelles) to ensure their own growth and proliferation, and bacteria usually reproduce asexually. Instead, viruses typically package their genetic information, such as DNA or RNA, inside a shell such as a protein. They need to use the host's organelles to replicate themselves. The bacteria use the "feet" on their shell to attach to the cell and then inject their genetic material into the interior of the cell. But in reality, viruses that use shells to wrap genetic material are not really alive. They do not have any life characteristics until they encounter a host. 3. Viruses and bacteria can also be distinguished based on whether they are beneficial to humans. Although it may seem unbelievable, our bodies are home to a multitude of microorganisms (which are separate entities from our body cells). If we use cells alone as the unit of measurement, most people are made up of about 90% microbes and 10% human cells. Many bacteria coexist peacefully with the human body, and many even perform very important jobs, such as producing vitamins, breaking down waste, and creating oxygen. For example, most digestive processes are carried out by intestinal flora. These bacteria also help maintain the acid-base balance in the human body. Although humans are very familiar with probiotics (such as intestinal flora), in fact, there are also some "good" viruses, such as bacteriophages. Bacteriophages can "hijack" bacterial organelles and kill bacteria. Yale researchers have also designed a virus that can fight brain tumors. But most viruses are harmful to the human body and have no good effects. 4. See whether the microorganism meets the standards of life. Although there is currently no standard and precise definition of what constitutes life. But there is no doubt among scientists that bacteria are alive. Instead, bacteria are more like zombies: They're not dead, but they're not alive either. Viruses do have many of the characteristics of living things, such as having genetic material, evolving through natural selection over time, and being able to multiply. However, viruses do not have cell structures or their own metabolism; they require hosts to multiply. In other aspects, viruses do not meet the requirements of living organisms. |
