What Are Bactericidal Antibiotics
Bactericidal antibiotics are a class of drugs that can directly kill bacteria. Its mechanism of action is quite specific, and it can exert force on the key link of bacterial growth and reproduction.
or act on the synthesis of bacterial cell walls, blocking the construction of cell walls, just like the wall of a house cannot be firmly built, and bacteria are prone to rupture and death due to imbalanced osmotic pressure. For example, beta-lactam antibiotics can combine with specific penicillin-binding proteins on the bacterial lining to inhibit transpeptidase activity, interfere with the cross-linking of cell wall peptidoglycans, and cause cell wall defects.
Or act on the synthesis process of bacterial proteins, making bacteria unable to normally produce proteins required for life activities. For example, aminoglycoside antibiotics can bind to the 30S subunit of the bacterial ribosome, causing misreading of the genetic code, synthesis of abnormal and non-functional proteins, and eventually death of bacteria.
Furthermore, it also acts on bacterial nucleic acid metabolism, hindering the replication and transcription of bacterial genetic material, causing bacteria to lose their ability to reproduce, and then die.
Bactericidal antibiotics are effective in anti-infective treatment, which can quickly remove pathogenic bacteria, relieve diseases, and save patients from pain. However, when applying, it should be done with caution. Reasonable selection should be based on the type of pathogenic bacteria, drug susceptibility results, etc., and attention should be paid to their adverse reactions in order to achieve the best therapeutic effect.
