What is Antimicrobial Resistance? What does resistance mean

Antimicrobial resistance refers to the tolerance and resistance of a pest to a certain pesticide that has been repeatedly exposed to it for a long time. In agricultural production, it is manifested in the reduction of the sensitivity of plant pathogenic bacteria, insects, grasses and rodents to pesticides, which is also the main reason for the decline of pesticide control effect. There are many reasons for the emergence of antimicrobial resistance, including changes in the biological characteristics of the pest itself, enhanced detoxification enzyme activity in vivo, reduced sensitivity of target sites, and changes in pesticide permeability.

Drug resistance, also known as drug resistance, refers to the reduced sensitivity of pathogens and tumor cells to chemical drugs. When a drug fails to kill or inhibit the pathogen, the term resistance is equal to drug dose failure or drug tolerance. It also refers to the situation that the same dose is not as effective as the original due to long-term medication.

In order to maintain the effectiveness of antibiotics, attention should be paid to their rational use.

Drug resistance is that bacteria lose their sensitivity to drugs, making ** lose their effectiveness or reduce their efficacy. This is related to substandard medications, incorrect dosages, irregular medication and overtreatment.

The bactericidal effect of antibiotics is mainly to interfere with the biochemical and metabolic processes of pathogenic bacteria, thereby affecting their structure and function, causing them to lose their ability to grow and reproduce, and to inhibit or kill bacteria.

After repeated contact between bacteria and drugs, the sensitivity of bacteria will decrease or even disappear after the bacteria gradually adapt to the drugs, resulting in reduced or ineffective antimicrobial drugs against drug-resistant bacterial infections.

There are only two ways to determine drug resistance: 1. Do a drug susceptibility test. It is to inoculate bacteria in a medium containing drugs, and look at the growth of bacteria to determine whether the bacteria are resistant and the degree of resistance.

But people who can't cultivate bacteria can't do it) 2. **No effect.

There are two types of drug resistance: primary drug resistance and secondary drug resistance. The bacteria that make you sick are resistant to antibiotics, which is primary antibiotic-resistant; Drug resistance occurs due to your inappropriate dosage (wrong dosage, usage or irregular medication, etc.), which is secondary drug resistance.

It is an attempt to take or use an antibiotic that causes the virus to become immune to such a drug.

Resistance of some animal microorganisms to drugs.

Drug resistance refers to the tolerance of microorganisms, parasites and tumor cells to chemotherapy drugs. Antimicrobial resistance includes tuberculosis bacteria, viral resistance, and more common cases, such as hepatitis B virus, which develop resistance to antiviral drugs for hepatitis B. Mycobacterium tuberculosis is resistant to anti-tuberculosis drugs, and pyogenic bacteria, such as streptococcus, are resistant to penicillin, and some bacteria may be resistant to cephalosporins or other antimicrobials.

Drug resistance refers to drug resistance, which refers to the tolerance of microorganisms, parasites and tumor cells to the action of chemotherapy drugs.

According to the cause of drug resistance, it can be divided into acquired resistance and natural resistance. Natural resistance can also occur in pathogens in nature, such as a strain of bacteria.

When antibiotics are used for a long time, the majority of susceptible strains are continuously killed, and drug-resistant strains multiply in large numbers to replace sensitive strains, and the bacterial resistance rate of the drug continues to increase, which is believed to be the main reason for the emergence of drug-resistant bacteria. In order to maintain the effectiveness of antibiotics, attention should be paid to their rational use.
