An inventions of 20th centurie: The penicillin

Penicillin is an antibiotic that has its roots in a fungus called Penicillium notatum. As an antibiotic,penicillin kills bacteria and prevents them from continuing their growth, however, only has the power to fight those pathogens found in growht and multiplicattion, and not those who are still dormant. Penicillim and its beneficial properties were discovered acidentally by renowned British bacteriologist Alexandre Fleming in 1928, which realized that the presence of certain fungi on bacterial growth inhibited their growth. However, in order to producee large amounts of the antibiotic was necessary cooperation and contibutions of other geat bacteriologists,also Brithis, as Ernst Boris Chain and Howard Walter Florey. Penicillin is able to effectively fight the bacteria responsible for causing many diseases, among which we find the pneumococci, streptococci, gonococci, meningococci, the clostridium tetani and the spirochete. The last two are responsible for causing tetanus and syphilis, respectively.
