What is the significance of the presence of invincible bacteria?

Superbug does not refer to a specific type of bacteria, but to those bacteria that are resistant to a variety of antibiotics, and its accurate name should be "multidrug-resistant bacteria". These bacteria have a strong resistance to antibiotics and can escape the danger of being killed. The main superbugs that are currently of particular concern are:

Methicillin-resistant Staphylococcus aureus (MRSA), multidrug-resistant Streptococcus pneumoniae (MDRSSP), vancomycin enterococci (VRE), multidrug-resistant Mycobacterium tuberculosis (MDR-TB), multidrug-resistant Acinetobacter baumannii (MRAB), and the newly discovered Escherichia coli and Klebsiella pneumoniae carrying the NDM-1 gene, among others. Since most antibiotics do not work against them, superbugs have caused great harm to human health. <>

I have been in the intensive care unit for several years, and I am afraid that my nose, pores, and nails are all these drug-resistant bacteria, Acinetobacter baumannii, Klebsiella pneumoniae, Maltophage pseudospora ......Taking a bath every day and rubbing your hands with disinfectant may not be able to completely remove it. I feel that these drug-resistant bacteria are like my aunt's cockroaches, stubborn and can't be **, but they won't make a big name. They are not too pathogenic, they only bully the old, weak and seriously ill, and young and middle-aged people such as Zhihu netizens, I am afraid that they should not worry too much.

Patients whose body fluids have cultured these drug-resistant bacteria, even if they do not use sensitive antibiotics, generally have their original disease relieved and their underlying conditions improve, because the symptoms caused by drug-resistant bacteria will also be alleviated. The emergence of antibiotics selectively eliminates bacteria and induces bacteria to develop drug resistance, and drug-resistant bacteria will also prompt human beings to develop new antibiotics. At present, we are more worried about viruses than bacteria.

Once this news spreads, it will cause a lot of panic again. But there's no need to worry too much. If the news is true, the bacterium is not very transmissible and is not yet lethal.

There is still time to develop a new antibiotic. This is the general trend, with the presence of antibiotics, sooner or later such superbugs will appear. Once a deadly bacterium with a high transmissibility rate emerges and becomes resistant to all antibiotics, it is really helpless.

All we can do is try not to abuse and rely on antibiotics in our daily lives. <>

On May 26, the U.S. Centers for Disease Control and Prevention confirmed that the first case of "invincible bacteria" was found in the United States, which could spread rapidly if not properly defended, and the terrible thing is that all antibiotics at this stage are ineffective, even colistin, the only antibiotic that can fight the 'nightmare bacteria', is powerless against this "invincible bacteria". "Invincible bacteria"i.e. "superbugs".

Bacteria are constantly evolving, and the emergence of pan-resistant bacteria has brought a shortcut to those with strong aggression and virulence to acquire pan-drug resistance.

The misuse of antibiotics has led to the increasing resistance of bacteria, and the misuse of antibiotics is the main cause. According to incomplete statistics, at least 10,000 patients die in the United States every year due to ineffective antibiotics. In addition, antibiotics are also overused in livestock, which reduces their resistance to disease in another way.

It's also a warning from nature about our misuse of antibiotics.

The U.S. Centers for Disease Control and Prevention confirmed on the 26th that the first case of "invincible bacteria" was found in the United States, which is resistant to all antibiotics at this stage. This "invincible bacteria" is the bacteria that carry the MCR-1 gene. This gene makes bacteria resistant to all current antibiotics, including colistin, which is considered the "last line of defense".

What is the reason for the emergence of this "invincible bacteria"? The misuse of antibiotics is a major cause of increasing bacterial resistance.

The emergence of "invincible bacteria" has caused people to worry, but we should not be so alarmed. In fact, in medicine, the battle between antibiotics and bacteria has been going on, and it is inevitable that bacteria will develop drug resistance. Only a reduced dose of antibiotics and a reasonable dose of antibiotics can slow down this process.

At the same time, the development of new antibiotic drugs can also solve this problem.

A 49-year-old woman in the United States went to the doctor for a urinary tract infection and finally found this so-called "superbug", which is reported to be ineffective at this stage, including colistin, which doctors consider the "last line of defense". Harvard biologists warn that the bacterium could spread quickly!!

Scared the baby to death [decay] [decay].

It is understood that the misuse of antibiotics is the main reason for the increasing resistance of bacteria. Looking back, I have always felt that we use too many antibiotics in China every year, how much antibiotics are used up every year, and our immune cells have not been able to evolve, while bacteria have been escalating, and the consequences can be imagined......Terrible! This is the inevitable result of antibiotic abuse, and all we can do is wash our hands frequently, protect ourselves, and don't let the Resident Evil really happen.

Heart congestion... As soon as I caught a cold, I found that there were invincible bacteria.

When you see an invincible bacteria, you should think that it is an invincible bacteria, which will not be killed, and it is an immortal body. In fact, this invincible bacterium refers to cases of bacterial infections that are resistant to all known antibiotics, and if this superbug spreads, it can pose a serious danger of daily infection.

Bacteria that no antibiotic can kill, think about how terrible it is, if it spreads, humanity will face extinction, it will definitely be even more terrifying than SARS in 03.

I saw the news a few days ago, and it is said that it can resist all current antibiotics, so if you are infected with this bacteria, basically the current medical conditions are not possible, and we should actively think about and solve the problem of human abuse of antibiotics. The misuse of antibiotics is a major cause of increasing bacterial resistance.

The news of the discovery of invincible bacteria in the United States has aroused special attention in the world, this invincible bacteria can not be dealt with, all antibiotics at this stage are helpless, the United States has found the first case of "invincible bacteria", some experts suggest that in order to avoid infection, the public should wash their hands carefully, fruits and vegetables should be thoroughly washed before eating, and other ingredients should be handled in the right way. Cases of invincible bacteria have been detected in the United States, and it is unlikely that they have spread to other places so far.

The discovery of the first case of "invincible bacteria" in the United States is itself fake news. The so-called "invincible bacteria", the scientific name is: super drug-resistant bacteria. In recent years, it has been detected in many places at home and abroad. It's not a new thing for a long time.

Superdrug-resistant bacteria are a type of bacteria, a variant of staphylococci that are resistant to almost all drugs. In layman's terms, this bacterium has been selectively cultivated by antibiotics and has become resistant to all drugs currently used in medicine, so any drug is helpless and powerless against it.

This time, the news just changed the name of the superdrug-resistant bacteria, and nothing else was new. The battle between antibiotics and bacteria has been going on, and it is inevitable that bacteria will develop resistance. Only a reduced dose of antibiotics and a reasonable dose of antibiotics can slow down this process.

At the same time, the research and development of new antibiotic drugs is the most important.

As soon as you hear the invincible bacteria, you can understand that this is a particularly powerful bacteria, and nothing can destroy it, so it is called an invincible bacteria. Doesn't it sound scary, this invincible bacteria is unexpectedly incurable, and all antibiotics are useless at this stage, so what should we do? d(őд

Some experts suggest that to avoid infection, the public should wash their hands carefully, wash fruits and vegetables thoroughly before eating, and handle other ingredients in the right way. Cases of invincible bacteria have been found in the United States, and they should not have spread to other places yet, "This is a crisis, a global crisis," she warned.

Therefore, we should pay attention to our physical health and safety, wash our hands frequently, and seek medical attention in time if we find that we are not feeling well. (゜

The U.S. Centers for Disease Control and Prevention confirmed on May 26 that the first case of "invincible bacteria" was found, and it is resistant to all antibiotics at this stage.

This is because the bacterium is resistant to all antibiotics at this stage, including colistin, which is considered the "last line of defense". So it is called "invincible bacteria" (* too scary birds

Has anyone been infected?

A 49-year-old woman in the United States was found infected with the bacterium after seeking medical attention on April 26 with symptoms of a urinary tract infection, according to a report in the journal Antimicrobial Agents and Chemistry**, the journal of the American Society of Microbiology. The report did not say what the woman's condition was.

Why do you have such a powerful bacteria?

The misuse of antibiotics is a major cause of increasing bacterial resistance.

1. If the patient is sick, he will take certain antibiotics.

2. Antibiotics are also abused in livestock, which reduces their disease resistance effect from another aspect.

What should you do as an ordinary person?

1. Wash your hands frequently, wash your hands carefully, wash fruits and vegetables thoroughly before eating, and use the correct method when handling other ingredients.

2. Don't take antibiotics at every turn.

Globally, pharmaceutical companies must be pushed to develop new drugs to combat "superbugs" with strong drug resistance. In addition, strengthening the supervision of the application of existing drugs is also to protect antibiotics to a certain extent.

There are many natural enemies of bacteria, such as temperature and drugs, many bacteria cannot survive in high temperature conditions, and there are many bacteria that can be used by drugs

If the natural enemy of human beings is bacteria, then the natural enemy of bacteria must be high temperatures, and bacteria will be killed in the case of high temperatures, and they will not be resurrected again.

The natural enemy of bacteria should be bacteriophages, as the name suggests, they have a phagocytic effect on bacteria, killing the cells of bacteria.

The natural enemy of bacteria is the bacteriophage, and phage scientists have discovered that it is actually a virus, and with it the number of bacteria on the earth is suppressed.

Whether there is harm or not is for human beings.

Bacteria are everywhere, but not all bacteria can pose a threat to the human body, because most of them are blocked or eliminated by the body's **, mucous membranes, lysozyme and other structures and substances. Only bacteria that cross the three barriers of the body's immunity can cause harm to the human body.

In addition, some bacteria are beneficial to the human body, the most typical such as lactic acid bacteria, which can promote the digestion of food by the body. There are also bacteria that are used to produce vaccines, to ferment (e.g., yogurt), to synthesize certain important proteins as cells that receive the gene of interest, and to preserve certain genes in gene libraries. The development of contemporary bioengineering is deeply dependent on bacteria.

The so-called "outside the mountain, Qingshan Lou Wailou", bacteria are experts in invading other things, but they don't know that the praying mantis catches cicadas, the yellow finch is behind, and behind the bacteria, there is its natural enemy-bacteriophage? Bacteriophages were discovered in 1915, and like other viruses, they can pass through bacterial filters? They resemble tadpoles, with a round or polygonal head followed by a tubular tail and 6 tail filaments at the ends.

When the phage infects the bacterial cell, the tail filament first grabs the cell wall of the bacterium and secretes an enzyme to dissolve the cell wall of the bacterium to form a hole, and then the tail sheath penetrates into the cell and injects the nucleic acid from the head into the cell like a syringe?

After these nucleic acids enter the cells of bacteria, they become the "kings" of the cellsIt commands the cell to stop the original synthesis of the substance and instead make the substance needed for the phage's progeny? Finally, it also causes the cell wall of the bacteria to rupture, releasing new bacteriophages?

From the beginning of the invasion to the final host cell "the country is ruined", the phage takes the "fungus" and "fungus" to open up a new colony, and it generally only takes 20 minutes to replicate about 150 phages in the cell of a bacterium? This bacteriophage is usually called a virulent bacteriophage, and is destroyed by a virulent bacteriophage? Are dissolved microorganisms called susceptible bacteria? Bacteriophage.
