What are antibiotics for and what are antibiotics used for?

Antibiotics are used to kill germs.

However, it should not be used indiscriminately, and if antibiotics are used regularly, the virus will produce antibodies, and if you are infected with such viruses in the future, the antibiotics will not work.

Until new antibiotics are available, there will be no cure for these viruses.

Therefore, try to use antibiotics sparingly and follow your doctor's instructions.

It is anti-inflammatory, can not be eaten casually, there are many people allergic to some antibiotics, the consequences of indiscriminate use are very serious, and they can only be used under the guidance of a doctor.

Antibiotics are a class of secondary metabolites with anti-pathogen or other activities produced by microorganisms (including bacteria, fungi, actinomycetes) or higher animals and plants in the course of life, and can interfere with the development and function of other living cells. Antibiotics commonly used in clinical practice include extracts from microbial culture broths and chemical synthesized or semi-synthetic compounds.

In layman's terms, antibiotics are drugs used for various bacterial infections or inhibition of pathogenic microbial infections.

Don't abuse ......Antibiotics are antimicrobial like penicillins, cephalosporins, ......It is best to prescribe the right medicine, mix it, and use it crosswise.

The antibacterial or bactericidal effect of antimicrobial agents such as antibiotics is mainly aimed at the mechanism of "bacteria have but humans (or other animals and plants) do not", including four major mechanisms of action, namely: inhibiting bacterial cell wall synthesis, enhancing bacterial cell membrane permeability, interfering with bacterial protein synthesis and inhibiting bacterial nucleic acid replication and transcription.

Antibiotics refer to a class of secondary metabolites with anti-pathogen or other activities produced by microorganisms (including bacteria, fungi, actinomycetes) or higher animals and plants in the course of life, and can interfere with the development and function of other living cells. Antibiotics commonly used in clinical practice include extracts from microbial cultures and chemical synthesized or semi-synthetic compounds.

Antibiotics are generally used to ** infections caused by tiny pathogens in people's bodies, and some types of antibiotics also have other effects. Antibiotics already belong to a kind of drug, and are divided into different types, different types of antibiotics produce different effects, must not be taken at will, to be taken correctly under the guidance of doctors in regular hospitals, and actively cooperate with the doctor's **, after the use of antibiotics, we must pay attention to observe the physical condition, and take measures in time to prevent adverse reactions and cause more serious consequences.

Problem description: What is an antibiotic?

Analysis: A long time ago, it was found that some microorganisms infiltrated by dust had an inhibitory effect on the growth and reproduction of other microorganisms, and this phenomenon was called antibiotic. With the development of science, people have finally revealed the essence of the antibiotic phenomenon, found substances with antibiotic effects from some microorganisms, and called this substance antibiotics, such as penicillin produced by Penicillium and streptomycin produced by Streptothrix griseus have obvious antibacterial effects.

Therefore, people call a class of chemicals produced by certain microorganisms in the course of life and have an inhibitory or killing effect on some other pathogenic microorganisms as antibiotics.

Because some of the first antibiotics were discovered to have a bactericidal effect, antibiotics were once called antibiotics. However, with the continuous development of antibiotics, antiviral, antichlamydia, antimycoplasma, and even anti-tumor antibiotics have been discovered and used in clinical practice. The emergence of anti-tumor antibiotics shows that the chemicals produced by microorganisms have the effect of inhibiting or inhibiting the proliferation or metabolism of cancer cells in addition to the original inhibition or killing of some pathogenic microorganisms, so the definition of modern antibiotics should be:

Chemicals produced by certain microorganisms that inhibit the proliferation of microorganisms and other cells are called antibiotics.

An antibiotic is a substance produced by various microorganisms (including bacteria, fungi, actinomycetes) that kills or inhibits other microorganisms. Antibiotics are divided into natural antibiotics and artificial semi-synthetic antibiotics, the former is produced by microorganisms, and the latter is a semi-synthetic product obtained by structural modification of natural antibiotics.

In 1941, antibiotics were really used in clinical practice, and in 1981, the fourth national antibiotic academic conference in China defined antibiotics as chemicals produced by certain microorganisms and substances that can inhibit the proliferation of microorganisms and other cells.

1) - Lactams: the most variety, the most widely used, this class includes two parts. Penicillin (quinnary cyclolactam):

Commonly used varieties are penicillin sodium, penicillin potassium, ammonia sunbylsibil rolling tremor sodium, amoxicillin, piperacillin, penicillin v potassium, etc. Cephalosporins (six-membered cyclolactam): commonly used varieties are cephalexin, cefadroxil, cefazolin sodium, cefradine, ceftriaxone sodium and other "cephalosporins".

2) Aminoglycosides: commonly used varieties are streptomycin, gentamicin, kanamycin, amikacin, nomicin, etc.

3) Tetracyclines: tetracycline, oxytetracycline, doxycycline, minocycline, etc.

4) Macrolides: commonly used varieties are erythromycin, erythromycin, roxithromycin, madisomycin, acetylspiramycin, guitaromycin, etc.

5) Chloramphenicol: the commonly used variety is chloramphenicol.

6) Lincomycin: lincomycin, clindamycin.

7) Quinolones: haloperic acid, ofloxacin, lomefloxacin and other "floxacin".

8) Other major antibacterial antibiotics: commonly used are norvancomycin, fosfomycin, capreomycin, rifampicin.
