What pathogenic microorganisms are targeted by toxoid and antitoxin antibiotics?

Exotoxin: refers to a metabolite secreted outside the body of some pathogenic bacteria during the growth and reproduction process. Its main component is soluble protein. Strong toxicity.

Endotoxins: a general term for toxic substances present in bacteria. Its chemical composition is phospholipopolysaccharide

-complex, which is less toxic.

Both are antigens

Toxoids: For example, certain bacterial exotoxins can be detoxified after treatment with formaldehyde. The toxicity

although it disappears, The immunogenicity remains unchanged, so it still stimulates the body to produce antitoxins, so that the body can automatically immunize against certain diseases. They are widely used to prevent certain infectious diseases.

Equivalent to a vaccine, used for immune vaccination

Antitoxin: the corresponding antibody to bacterial toxins (usually exotoxins) or the immune serum containing such antibodies. It neutralizes the toxic effects of the corresponding exotoxins.

Equivalent to antibodies

Antibiotics: produced by microorganisms (including bacteria, fungi, and actinomycetes) or higher animals and plants during their daily life

A class of metabolites with antipathogenic or other activities, chemicals that can interfere with the developmental functions of other living cells. Works on bacteria, not viruses.
