Answer 1

Hey There! The discovery of penicillin, one of the world’s first antibiotics, marks a true turning point in human history — when doctors finally had a tool that could completely cure their patients of deadly infectious diseases.  Many school children can recite the basics. Penicillin was discovered in London in September of 1928. As the story goes, Dr. Alexander Fleming, the bacteriologist on duty at St. Mary’s Hospital, returned from a summer vacation in Scotland to find a messy lab bench and a good deal more.  Upon examining some colonies of Staphylococcus aureus, Dr. Fleming noted that a mold called Penicillium notatum had contaminated his Petri dishes. After carefully placing the dishes under his microscope, he was amazed to find that the mold prevented the normal growth of the staphylococci.  It took Fleming a few more weeks to grow enough of the persnickety mold so that he was able to confirm his findings. His conclusions turned out to be phenomenal: there was some factor in the Penicillium mold that not only inhibited the growth of the bacteria but, more important, might be harnessed to combat infectious diseases.
