Glycopeptides Bacteriostatic or Bactericidal
On the bacteriostatic or bactericidal characteristics of glycopeptide antibiotics
In the medical system, the properties of glycopeptide antibiotics are related to the difference between bacteriostatic and bactericidal, which is a key topic in medicine.
The study of glycopeptides in their bacteriostatic and bactericidal effects has undergone various experimental and clinical experiments. The mechanism of action of glycopeptides is firstly to bind closely with D-alanyl-D-alanine at the end of peptidoglycan, the precursor of bacterial cell wall, to inhibit the synthesis of peptidoglycan, resulting in the blockage of bacterial cell wall construction.
Under certain conditions, glycopeptides can slow down the growth and reproduction rate of bacteria. In case of moderate lack of nutrients in the bacterial growth environment, or when the concentration of drugs does not reach the extreme, although the bacteria do not die immediately, the proliferation trend is gradually weakened. This is because the inhibition of glycopeptides on cell wall synthesis makes it difficult for bacteria to divide as usual, and they are in a state of growth inhibition. It is like a boat meeting a slow flow. Although it has not stopped sailing, its speed gradually slows down.
As for the sterilization power, if the concentration of drugs is sufficient, and the bacteria grow vigorously and have active metabolism, glycopeptides can cause serious damage to the bacterial cell wall, and eventually the bacteria will lyse and die. Because the cell wall is a barrier for bacteria to resist the outside world, if it is damaged, the bacteria cannot maintain the intracellular homeostasis, just like the wall of the house collapses, and everything in the house is exposed to danger, and its vitality is lost.
And the antibacterial and antibacterial performance of glycopeptides to different strains are also different. Gram-positive bacteria have a special cell wall structure, rich in peptidoglycans, and glycopeptides have strong binding force to them, so the antibacterial effect is often good. For some mutated or bacteria with special drug resistance mechanisms, the effect of glycopeptides may be biased to inhibit bacteria. In order to survive, bacteria develop coping strategies to reduce the killing of drugs.
In summary, glycopeptide antibiotics have both antibacterial and antibacterial properties. The bias of their effects depends on many factors such as drug concentration, bacterial growth status and strain characteristics. When a doctor uses it, he must carefully observe all the reasons for the situation and use precise medicine to obtain the best effect and heal the patient's disease.
