What are Fungi?

Fungus is a eukaryote. The most common fungi are various types of fungi, and fungi include molds and yeasts. More than 70,000 fungi have been discovered, and it is estimated that only a small part of all exist. Most fungi were originally classified into animals or plants, but now they have become their own realm, divided into four categories. Fungi are themselves different from plants, animals, and bacteria. The biggest difference between fungi and three other organisms is that the cells of the fungus have a cell wall containing chitin (also known as chitin, chitin, chitin) as the main component, and the cell wall of the plant is mainly composed of cellulose different.

The origin, evolution and evolution of fungi

In 1550 BC, there was a doctor using lard in ancient Egypt.

1. Obstruction

Sugar derivatives

Mainly composed of derivatives of aminohexose.

Peptide antibiotics

It consists mainly or entirely of amino acids and has certain characteristics of polypeptides or proteins.

Polyene antibiotics

There are multiple double bonds in the molecular structure.

Macrolide antibiotics

It consists of one or more monosaccharides and forms a huge aromatic lactone compound with the carbon chain.

Tetracyclic antibiotics

Both have four condensed benzene rings.

Purine antibiotics

Both contain purine rings.

Act directly on bacterial cells

Antibiotics can selectively act on specific links in the cell's DNA, RNA, and protein synthesis systems, interfere with the cell's metabolism, hinder life activities or stop growth, or even die. It is different from non-selective ordinary disinfectants or bactericides.

Selective

The effects of antibiotics are selective. Different antibiotics have different effects on different pathogens. The type of pathogens that are sensitive to an antibiotic is called the antibiotic's antibiotic spectrum (

1. Nervous system toxicity; 5 antibiotics that baby is most afraid of

2. Toxic reactions of hematopoietic system;

3. Liver and kidney toxicity;

4. Gastrointestinal reactions;

5. Antibiotics can cause dysbiosis, causing vitamin B family and K deficiency;

6, antibiotic allergic reactions are generally divided into anaphylactic shock, serotype reactions, drug fever, rash, angioedema and allergic myocardial damage.

7. Antibiotic sequelae effect refers to the sequelae biological effect after drug withdrawal.

1. Antibiotics are mainly used in medicine.

To human pathogenic fungi

Common fungi

The whole of the mycelium developed from a section (or a cluster) of mycelium or a (or a group of) spores on a natural substrate or artificial medium is called a colony. Fungal

Plant roots and fungi also have

Plants and animals are composed of cells, and there are nucleus in the cells. Only fungi in microorganisms have true nucleus and complete organelles, so they are also called eukaryotic cell-type microorganisms. Bacteria only have primitive nuclear structure, no nuclear membrane and The nucleoli has few organelles and belongs to prokaryotic cell type microorganisms. The virus has no cell structure and belongs to protozoan microorganisms. Therefore, although some fungi are also tiny and can make people sick, they are fundamentally different from bacteria and viruses.
