Determine Antibiotic Bactericidal or Bacteriostatic
The method of distinguishing between antibiotic sterilization and bacteriostatic
If you want to distinguish whether antibiotics are bactericidal or bacteriostatic, you need to follow the scientific method and explore in detail.
First, look at its impact on bacterial growth. In a suitable medium, inoculate an appropriate amount of bacteria and apply the desired antibiotic. If the number of bacteria decreases sharply after a certain period of time, or even nearly goes extinct, this antibiotic is likely to have the ability to kill bacteria. Cover because it can directly kill bacteria, making them unable to survive and multiply. If bacteria are not extinct, but their growth and reproduction are significantly inhibited, and the number of growth is slow, then most of them are bacteriostatic antibiotics. Its function is to inhibit the growth process of bacteria, making it difficult to multiply rapidly.
Second, observe the change of bacterial morphology. With the help of microscopy and other tools, observe the morphology of bacteria before and after the use of antibiotics. If serious structural damage such as bacterial cell wall rupture and cell membrane damage is seen, this is a sign of the action of bactericidal antibiotics. Because bactericidal antibiotics can destroy the key structure of bacteria and cause their death. If the bacterial morphology does not show obvious damage, but only the growth trend slows down, it tends to be bacteriostatic antibiotics, which mainly interfere with the growth links such as bacterial metabolism, rather than directly destroy its structure.
Third, consider the mechanism of action of antibiotics. Different mechanisms of action often determine whether it is bactericidal or bacteriostatic. If it acts on the synthesis of bacterial cell walls, the cell walls cannot form normally, resulting in the rupture and death of bacteria due to unbalanced osmotic pressure, most of them are bactericidal antibiotics. If it acts on the bacterial protein synthesis or nucleic acid synthesis process, it only interferes with its normal metabolism and slows down growth, which is mostly a bacteriostatic antibiotic.
In short, in order to accurately determine whether an antibiotic is bactericidal or bacteriostatic, when the above methods are combined and carefully analyzed, a definite conclusion can be obtained, providing a solid basis for clinical rational drug use.
