What do antibiotics do and what do antibiotics do

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.

01 Antibiotics are commonly known as anti-inflammatory drugs (not anti-inflammatory drugs in the real sense), which can selectively inhibit or kill pathogenic microorganisms at a certain concentration, and are important drugs for the prevention and infection of diseases. This is the most well-known anti-infective effect.

02 There are also some roles that everyone is not very familiar with, that is, the role in breeding. Adding antibiotics to the feed can change the intestinal wall, thin the intestinal wall, and make the intestinal villi longer, so that the absorption area increases, and the contact area between the intestinal wall and nutrients can be increased and the absorption can be increased. Increases the rate of weight gain in animals.

03 Antibiotics can selectively kill intestinal bacteria in the intestines, reduce harmful bacteria, reduce unnecessary nutrient consumption, allow beneficial bacteria to multiply in large quantities, and help animals synthesize more nutrients.

04 It can also make animals less sick, reduce unnecessary consumption, and let animals eat and sleep more meat every day. It's just that there is such a role, but this practice is not correct, this breeding method is now very farms for economic benefits, and abuse of antibiotics, which will lead to a decrease in animal resistance, bacterial resistance after illness has no medicine.

I hope everyone has a sense of social responsibility and I hope it can help you.

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. At present, there are no less than 10,000 known natural antibiotics.
