The Discovery of Penicillin

The discovery of PENICILLIN R. CH3 CH3 COOH TODAY WE USE A HOST OF ANTIBIOTICS TO TREAT DISEASES AND TO PREVENT THE ONSET OF INFECTIONS. DO YOu KNOW THAT THESE LIFE-SAVING ANTIBIOTICS WERE NOT AVAILABLE UNTIL tys THE EARLY 194OS? PENICILLIN WAS DISCOVERED BY A STROKE OF LUCK AT ST. MARY'S HOSPITAL IN LONDON BY DR. ALEXANDER FLEMING. AN ACCIDENT IN 1928, FLEMING WAS RESEARCHING STAPHYLOCoccus AUREUS, A DISEASE-CAUSING BACTERIUM, WHEN HE LEFT FOR A LONG VACATION WITH HIS FAMILY. WHEN HE RETURNED TO HIS LAB, HE FOUND THAT HIS LAB WAS COMPLETELY CLUTTERED. HE HAD FORGOTTEN TO CLEAN UP BEFORE LEAVING! HE STARTED TO SORT OUT THE DIRTY PETRI DISHES THAT WERE COATED WITH STAPHYLOCOccus BACTERIA. DISCOVERY ONE OF THE PETRI DISHES HAD MOLD ON IT. THE MOLD WAS CIRCULAR IN SHAPE AND THE AREA AROUND THE CIRCLE WAS FREE OF THE BACTERIA STAPHYLOCoccus. FLEMING CONCLUDED THAT THE BACTERIA ON THE PETRI DISH AROUND THE RING MUST HAVE BEEN KILLED BY SOME SUBSTANCE THAT HAD COME FROM THE MOLD. FLEMING DISCUSSED THE MOLD WITH MYCOLOGIST C.J. LA TOUCHE WHO HAD HIS OFFICE RIGHT BELOW FLEMING'S. ROLE OF LUCK MOLD SAMPLES TOGETHER, THEY EXAMINED THE MOLD CLOSELY AND FOUND OUT THAT THE MOLD IN THE PETRI DISH WAS A PENICILLIUM MOLD. FROM WHERE DID THIS MOLD COME? MOST LIKELY, FROM LA TOUCHE'S ROOM DOWNSTAIRS! LA TOUCHE WAS COLLECTING VARIOUS ТУРES OF MOLDS FOR HIS RESEARCH AND AS LUCK WOULD HAVE IT, SOME FLOATED UP TO FLEMING'S LAB. KINGSTON LA TOUCHE TEAM EFFORT HOWARD FLOREY THOUGH FLEMING UNDERSTOOD THE POTENTIAL OF PENICILLIN MOLD, HE WAS UNABLE TO ISOLATE THE ACTIVE ANTIBACTERIAL ELEMENT, PENICILLIN. IN 1940, TVWO SCIENTISTS AT OXFORD UNIVERSITY, HOWARD FLOREY AND ERNST CHAIN WERE ABLE TO ISOLATE PENICILLIN. IN 1941, CHARLES FLETCHER, A DOCTOR EMPLOYED AT A HOSPITAL IN OXFORD, CAME TO KNOW ABOUT THEIR WORK. ERNST CHAIN HE HAD A PATIENT WHO WAS NEARLY ON THE VERGE OF DYING BECAUSE OF A BACTERIAL INFECTION IN HIS WOUNDS. DR. FLETCHER USED SOME PENICILLIN ON THE PATIENT AND THE WOUND MADE A REMARKABLE RECOVERY. ALL THE THREE MAIN SCIENTISTS FLEMING, FLOREY AND CHAIN WERE AWARDED THE 1945 NOBE PRIZE IN PHYSIO MEDICINE.
