The history of penicillin follows observations and discoveries of evidence of antibiotic activity of the mould Penicillium that led to the development of penicillins that became the first widely used antibiotics. Following the production of a relatively pure compound in 1942, penicillin was the first naturally-derived antibiotic.
In 1907 Alfred Bertheim synthesized Arsphenamine, the first man-made antibiotic. In 1927 Erik Rotheim patented the first aerosol spray can. In 1933 Robert Pauli Scherer created a method to develop softgels. William Roberts studies about penicillin were continued by Alexander Fleming, who in 1928 concluded that penicillin had an antibiotic ...
Antiseptics, which were used at the time to treat infected wounds, he observed, often worsened the injuries. [12] In an article published in the medical journal The Lancet in 1917, he described an ingenious experiment, which he was able to conduct as a result of his own glassblowing skills, in which he explained why antiseptics were killing ...
The mould was found to be a variant of Penicillium notatum (now called Penicillium rubens), a contaminant of a bacterial culture in his laboratory. The work on penicillin at St Mary's ended in 1929. The work on penicillin at St Mary's ended in 1929.

Overuse of antibiotics in kids under 2 years old may be linked to health issues later in life, a new study finds. But experts say the drugs are safe when used correctly and have been a "game ...
However, these classifications are based on laboratory behavior. The development of antibiotics has had a profound effect on the health of people for many years. Also, both people and animals have used antibiotics to treat infections and diseases. In practice, both treat bacterial infections. [1]
