Penicillin Bacteriostatic or Bactericidal

"On the Bacteriostatic or Bactericidal Properties of Penicillin"

Penicillin is widely used in medicine. However, there are many opinions on whether it is a bacteriostatic agent or a bactericidal drug, and it is worth exploring.

Watching the reproduction of bacteria is like weeds sprawling. The application of penicillin is like a good farmer treating the field, either controlling its growth or eliminating its roots. Its mechanism of action is related to the formation of the cell wall of the pathogen. The cell wall is like a barrier of the pathogen, protecting the inside and resisting external invasion. Penicillin can interfere with its synthesis and make the construction of the wall out of order.

If it is said to be bacteriostatic, it is because penicillin can slow down the proliferation of pathogens. If the germs are placed in the hotbed, penicillin enters, and the cold wind blows in, making their growth trend slightly suppressed. Although the germs do not die immediately, the way of reproduction is blocked, and the growth is slow, just like a car stuck in the mud, making it difficult to move forward. This is the method of fetters to prevent the spread of germs.

If it is about its sterilization, penicillin is like a fierce fire burning the forest, hitting the key of the germs. With its disturbance of cell wall synthesis, it causes the wall to be incomplete, and the germs are unable to resist the force of the outside world. When internal and foreign affairs are difficult, the germs are like rotten wood in the wind, which disintegrates with a bang, and the cells collapse, and the vitality is exhausted. This is a strategy to cut weeds and eradicate roots, so that the germs cannot be hidden.

However, the bacteriostatic or bactericidal properties of penicillin are not Its effectiveness is controlled by many factors. The types of pathogens have their own characteristics, and the response to penicillin is also different. Like different locks, the key to adaptation is required. Penicillin is suitable for pathogens, and whether it is adapted or not depends on its function. In addition, the concentration of the drug is also the key. When the concentration is low, it can only inhibit the reproduction of pathogens. If the concentration is increased, such as the fire of accumulation of fuel, the fire will become more and more fierce, and the effect of sterilization can be achieved.

When a doctor uses penicillin, he should carefully observe the state of the pathogen and measure the amount of the drug to clarify its bacteriostatic or bactericidal use. If used properly, it can drive away diseases and benefit living beings; if used improperly, it will be difficult to control the pathogen and the disease will prolong. Therefore, the bacteriostatic or bactericidal properties of penicillin are essential for medical practice.
