In the 20th century, Death rates in hospitals were increasing and this is due to infection to wounds when patients are being operated on. Bacteria entering the wound would cause infection to the blood, poisoning the patient. What was missing in the at this point of time was an antiseptic that could be taken through the mouth and destroying the bacteria in the body.However this was the 20th century thus such antiseptic seem like it will never be found.

But his excitement did not last long and soon forgotten. Soon Alexander Fleming found a new discovery which he called lysozyme was effective at destroying harmless microbes but seems ineffective at destroying microbes that cause diseases.

Alexander Fleming, however, did not give up and in the 1928 his diligence and hard work finally paid off. In his laboratory Fleming was in the middle of developing staphylococci. When he removed the lids of one of the culture, he found out that the dish containing the culture he mistakenly left open, which was contaminated by blue-green mold which grew to a point where-by it was visible and around the mold there was a halo that was inhibited. . Something produced by the mold was dissolving the bacteria.

After further testing, Fleming was able to isolate the juice of the mould and it was then that he named it penicillin. This new breakthrough destroyed such nasties as gonorrhea, meningitis, diptheria and pneumonia bacteria and it would not cause harm to humans. However, the medical community reacted coldly to this new discovery and were adamant that once a bacteria entered the body, there was nothing that could be done and thus seen as a non-event to them.

After much refinement they were able to develop a powdered form of penicillin. In 1941 the first human was successfully treated. Before long, penicillin was in full production. Fleming, Florey and Chain were awarded the Nobel Prize for Medicine in 1945.
