What causes superbugs to form? Please tell me.

The diseases caused by superbugs are no longer a fatal threat to human beings. Every infectious disease can be treated with antibiotics, but this was before antibiotics were abused. Every year, about 5% of antibiotics are abused all over the world, and the proportion in China is even close to 8%. It is precisely because of drug abuse that bacteria quickly adapt to the antibiotic environment. Various superbugs have been born one after another. In the past, a patient could survive with dozens of units of penicillin, but now millions of units of penicillin have no effect for the same condition. Because of the infection caused by drug-resistant bacteria, antibiotics can't be controlled, which eventually leads to the death of patients. In the 196s, the number of people who died of infectious diseases around the world was about 7 million every year, and this number rose to 2 million at the beginning of this century. The number of people who died of septicemia increased by 89%. Most people die from the difficulty of drug use caused by superbugs. People are trying to find a new drug to overcome superbugs, but it has never worked. Not only that, with the world's awareness of antibiotic abuse gradually reaching * * *, the status and role of antibiotics are suspected, but they are also strictly managed. While the germs spread, the research and development of antibiotics have gradually stagnated. Without antibiotics, this once powerful weapon, People began to look for inspiration to fight against diseases from the simple treatment methods in the past. Finding a healthy and natural treatment and using human autoimmune to resist the attack of superbugs has become a new knowledge of diseases for many people. The production of superbugs is completely a gene that has entered this bacteria. Some bacteria have been found to contain NDM-1 gene. Researchers believe that, The abuse of antibiotics is the reason for the emergence of superbugs. Antibiotics used to be a magical weapon for sterilization at the beginning, but bacteria have gradually evolved drug resistance. In recent years, superbugs that can resist multiple antibiotics have appeared repeatedly. Because the research and development speed of new antibiotics is relatively slow, Dealing with superbugs has become a difficult problem in modern medicine. There is a thing called defatted substance lipid that divides bacteria into two societies. The content of this thing in the cell wall determines whether bacteria can be colored by aniline pigment. Those that can be dyed are called Gram-positive bacteria, and the other is called Gram-negative bacteria. MRSA belongs to Gram-positive bacteria. At first, penicillin did not work on Gram-negative bacteria. However, a small number of MRSA strains quickly obtained the penicillin-resistant genes of Gram-negative bacteria. The widespread abuse of penicillin made the human environment worse for all bacteria, which caused great evolutionary pressure on the remaining drug-resistant bacteria, forcing them to adjust all the gene programs to reproduce. In the end, MRSA, which was originally rare, became the dominant species that survived after natural selection. At first, penicillin could almost completely destroy staphylococcus. After 3 years, that number has dropped to 1%. In the 196s, most doctors gave up penicillin with the help of dimethoxycillin. The new drug destroyed the resistance of penicillin-resistant staphylococcus, which lasted only a few years, and MRSA defeated dimethoxycillin again. More complex antibiotics appeared, but MRSA continued to gain stronger resistance. At present, more and more drugs can destroy MRSA infection. In addition to the traditional glycopeptide drugs vancomycin and teicoplanin, it is also beneficial to nazole, tigecycline and daptomycin. However, an enterococcus also produces antibodies to vancomycin. In hospitals, this enterococcus and MRSA are often neighbors parasitic on patients' wound bandages. We have reason to worry that enterococci will selflessly hand over this weapon to MRSA. The cost of fighting the super infection of "superbugs" has soared like a rocket launch. The prolonged hospitalization time of patients and the use of more expensive antibiotics will increase the annual expenditure by 3 billion dollars. The transition from penicillin to meticillin has increased the basic medical expenses tenfold. The more expensive and complicated antibiotics are used for treatment, which has led to greater drug resistance of "superbugs". In "Undead"
