A large number of “super bacteria” have been discovered internationally, such as extended-spectrum β-lactamase Enterobacter, multiple drug-resistant Mycobacterium tuberculosis, vancomycin-resistant Staphylococcus aureus, etc. Several super bacteria have been found in my country, such as feces. Enterococcus and Acinetobacter baumannii, super bacteria are caused by the use of antibiotics, most common bacteria are killed, so those bacteria that did not have a quantitative advantage, the drug-resistant “super bacteria” survived and began to multiply, And the dominant position makes the amount of antibiotics larger and larger, and the ineffective antibiotics are also increasing. Another situation is mutation. Although it rarely occurs, it is not without. The latest typical example is the new type of pneumonia virus. In the United States only two years since it appeared last year, a variety of mutations have occurred, leading to the Ruihui vaccine in the United States. The curative effect of it has dropped significantly, and after being screened by the Indian virus nest, it has become the current delta, which has become more difficult to defend.
