How do Antibiotics work

Until the last century, [Who discovered antibiotics] people did not know that the infection was caused by bacteria, bacteria were the number one cause of human death in the developed world. There were many types of diseases caused by bacteria such as pneumonia and diarrhea – which are caused by bacteria.

Antibiotics have been used to treat infections for centuries, do you know how anti-bacterial drugs or “antibiotics” were discovered

Who discovered antibiotics

The discovery of the world’s first antibiotic drug goes to Alexander Fleming, the discovery of penicillin by mistake. Returning from a holiday in Suffolk in 1928, Fleming noticed that a fungus, Penicillium notetum, had contaminated a culture plate of Staphylococcus bacteria that he had accidentally left open. Wherever the fungus grows on the plate. 

Created bacteria-free zones. In pure culture the mold broke apart and evolved. He found that P.W. Notum proved to be highly effective even at very low concentrations, [Who discovered antibiotics] was also diluted 800 times in preventing the growth of Staphylococcus, and was less toxic than the disinfectant used at the time.

Penicillin found early trials successful in treating human wounds, cooperation with British pharmaceutical companies ensured that large-scale production of penicillin was possible. 

Treatment with penicillin was highly successful, and the US government began to support mass production of the drug. By D-Day in 1944, penicillin was widely used throughout Europe and in hospitals to treat soldiers for infections. By the end of the Second World War, penicillin was given the nickname ‘drug of wonder’ and saved many lives. 

Penicillin Structure

The term “penam” is used to define the main structure of a member of a penicillin antibiotic. A molecular formula of this structure is R-C9H11N2O4S, in which R (R) is a variable side chain. 

Normal penicillin has a molecular weight ranging from 313 to 334 grams per molecule (the second of which is for G). The penicillin type containing additional molecular groups has a molecular group of about 500 g per molecule. For example, [Who discovered antibiotics] cloxacillin has a molecular group of 476 grams per molecule and dicloxacillin has a molecular group per gram per molecule
