There are so many microscopic creatures and certain things that will not help the world. Some people also help the world. I will introduce another part of the contents. Here are some bad things to introduce.

Many kinds of bacteria cause diseases even by humans, animals and plants. Humans are concerned about bacteria causing bacteria poisoning (bacteria live in oxygen-free space like cans), tetanus and E. coli. You should know that there are some good E. coli in your intestine. They help decompose food and send a simple life (yes, they make it smell of smell). There are also E. coli delivered to you from uncooked meat. These harmful bacteria make you very sick or even kill you.

We do not know good viruses in the world. They are an important part of evolution and natural selection. Weak and older animals are more sensitive to infection. These organisms are excluded from the population to allow more healthy animals to survive. However, the life cycle of the virus, the life cycle of the parasite only harm the organism. Some cells even destroy cells for reproductive purposes. And do not think you alone are sick. Virus attacks even plants and bacteria. No creatures are protected from damage. Examples of viruses include rabies, pneumonia, meningitis, etc.

Humans actually produce erroneously stronger bacteria and viruses. The idea of ​​natural selection is that weak creatures are killed and strong creatures survive and replicate. Think about bacteria for the time being. If you eat antibiotics that kill bacteria you will get better

However, because of its wide variety, some bacteria can survive in medicine. There are not enough bacteria to survive to hurt you now, but they are there. Antibiotics may not work again if they become ill to someone. You have hatching superb bacteria! It is happening in the hospital. We are eliminating predisposing diseases, but some mutant strains survived. You may not be able to cure people the next time you get sick.

Note: Antibiotic tolerance occurs when microorganisms carrying bacteria (bacteria, viruses, parasites, or fungi) are no longer affected by drugs that previously killed microbes or prevented microbial growth . Even in a population of microorganisms susceptible to a particular antimicrobial agent, at least some of the organisms are naturally tolerant and their proportion will increase as other organisms die with antimicrobial agents. After all, this process invalidates the drug against microorganisms.

Almost all antimicrobial agents are derived from those naturally produced by soil microorganisms. Imagine that the two kinds of microbes share the same environment and depend on the same nutrient source. If microbial A is capable of producing and secreting antimicrobial agents that inhibit or kill microorganism B, it will have a competitive advantage. Antimicrobial agents damage or kill their target microorganisms by breaking or blocking certain structural features (such as cell walls or cell surface receptors) or metabolic functions. Mutation of the gene or acquisition of the gene by the target microorganism may alter structural features or metabolic processes and the microorganisms and their progeny may no longer be sensitive to microorganisms or other antimicrobial agents that likewise kill or prevent growth There is sex.

Microorganisms account for over 90% of marine biomass. Microorganisms (or microorganisms) are microscopic organisms, which can be unicellular or multicellular. Microorganisms are very diverse and include all bacteria, archaea, and most protozoa. This group also includes specific microscopic animals such as some fungi, algae, rotifers. Many macroscopic animals and plants have microscopic early stages. Some microbiologists classify viruses (and viroids) as microorganisms, but others consider them as inanimate objects. In July 2016, scientists reported that they identified a group of 355 genes, including microorganisms living on Earth, from the last universal common ancestor of life (LUCA).
