Penicillin is a type of antibiotic, which is a drug extracted from the culture of Penicillium and is the first antibiotic capable of human diseases.

The inventor of penicillin, the British scientist Fleming, in his laboratory.

The discoverer of penicillin was the British bacteriologist Fleming. One day in 1928, Fleming was studying staphylococcus bacteria, which cause fever in the human body, in one of his modest laboratories. Since the lid was not properly closed, he noticed that the agar used to grow the bacteria had a layer of Penicillium attached to it.

This was from the window of a scholar who studied penicillium upstairs. To Fleming's surprise, in the immediate vicinity of Penicillium, the staphylococci suddenly disappeared. Fascinated by this serendipitous discovery, he managed to grow the mold in several experiments that proved that penicillin could kill all staphylococci in a matter of hours.

Fleming thus invented penicillin, the nemesis of staphylococcus.

In 1935, Philip Lee, a biochemist at the University of Oxford, and Flory, a physicist, became interested in Fleming's discovery. Chin was responsible for the cultivation of Penicillium and the isolation, purification and strengthening of penicillin, which increased its antibacterial power by thousands of times, and Florey was responsible for observing and testing animals. So far, the efficacy of penicillin has been demonstrated.

Due to the discovery and mass production of penicillin, the lives of millions of patients with pneumonia, meningitis, abscess, and sepsis were saved, and many wounded and sick people were rescued in time. The advent of penicillin caused a sensation in the world at that time. In recognition of this contribution to the benefit of mankind, Fleming, Chin and Florey were jointly awarded the Nobel Prize in Medicine and Physiology in 1945.

The bacteria farthest from penicillin are large, dark-colored, and vigorous; Bacteria that are closer to Penicillium are smaller, lighter in color, and less viable; The bacteria closest to Penicillium are the smallest, whitish in color, and apparently dead.

Penicillin, an antibiotic, was actually discovered in an accident? What exactly is the truth.

Penicillin is a -lactam drug, that is, penicillin, which is called penicillin, so why is it called penicillin, which is literally translated from the foreign name, as Chinese is penicillin. Now penicillin belongs to the class of lactams, and when using penicillin or penicillin, it is important to pay attention to whether the patient has allergies, whether there is a history of allergies, especially whether there is a history of anaphylactic shock. There is a history of anaphylactic shock, penicillin is contraindicated.

In addition, patients with a history of allergies are not advocated, especially those with a history of penicillin allergy, and those who are allergic to other drugs should be used with caution. What kind of infection can penicillin control, the main infection to be controlled is cocci-based infection, especially Streptococcus pneumoniae infection. However, when we apply it, we must apply it under the guidance of a doctor, because the application of these drugs is high-risk, and the disease must be correct, otherwise due to improper application, one may cause adverse consequences, and then it will make ** fail.

Penicillin is another name for penicillin, is the name of the direct transliteration of the English name of penicillin, penicillin mainly plays a bactericidal role by destroying the cell wall of bacteria, penicillin is an antibiotic extracted from penicillium, *** is very small, but the most important thing is that there is penicillin allergy, so a skin test must be done before applying penicillin. Penicillin allergic reactions can be fatal, so it should only be used in a medical setting.

Penicillin is the current use of penicillin G, which is a transliteration of English. This drug belongs to the earliest application of penicillin drugs, which has a strong antibacterial effect and has a relatively good effect on bronchitis, pneumonia, tonsillitis and other diseases. Penicillin mainly acts on the cell wall of bacteria, and has no ** effect on bacteria without cell wall, and the antibacterial spectrum is relatively narrow.

In addition, drug resistance is easy to occur, so it is best to do a drug susceptibility test before taking the drug, and if you have drug resistance, you cannot continue to use it.

Penicillin (or transliterated as penicillin) is also known as penicillin G, peillin G, penicillin, penicillin, penicillin sodium, benzylpenicillin sodium, penicillin potassium, benzylpenicillin potassium. Penicillin is a kind of antibiotic, which refers to a class of antibiotics that contain penicillane in the molecule, can destroy the cell wall of bacteria, and play a bactericidal role during the reproduction period of bacterial cells, and is an antibiotic extracted from Penicillium.

Penicillin is a medicine, also called penicillin, which is an antibiotic.

Penicillin (benzylpenicillin penicillin) is also known as penicillin G, peillin g, penicillin, penicillin, penicillin sodium, benzylpenicillin sodium, penicillin potassium, benzylpenicillin potassium. Penicillin is a type of antimicrobial

Penicillin refers to penicillin. 1. Penicillin 1, penicillin (or transliteration of penicillin) is also known as penicillin G, peillin G, penicillin, penicillin, penicillin sodium, benzylpenicillin sodium, penicillin potassium, benzylpenicillin potassium. Penicillin is a type of antibiotic that contains penicillane in the molecule and can destroy the cells of bacteria.

What is penicillin Penicillin generally refers to penicillin, penicillin, mycin is a type of antibiotic, which refers to a class of antibiotics that contain penicillin in the molecule, can destroy the cell wall of bacteria and play a bactericidal role during the reproduction period of bacterial cells.
