Презентация на тему I will tell you about Alexander Fleming

Discovery of medicinal properties penitsyliumu, comprehensive research and receiving

their first batches of the antibiotic penicillin like a detective story. Doctors have long drawn attention to the unusual properties of green mold. The first steps on the long road to penicillin were made by Russian doctors VA Manaseyinym and OG Polotyebnovym

in England bacteriological laboratory at the Medical College of

St. Mary A. Fleming studied the effect of various antiseptics on staphylococci - germs festering diseases. Fleming had already long defined his main task in the research: he was looking for a substance that could destroy pathogens without harming the cells of the patient.

substance that killed bacteria - lysozyme. Lysozyme was found in saliva, in breast milk, fish roe, the leaves and stems of plants, etc.. But lysis did not To the substance that would allow medicine to obtain a glorious victory in the fight against pathogenic organisms.

with his colleague Dr. Price, who came to consult

him, looking for a cup of old cultures. In one of the cups they saw culture where grown fungi and bacteria colonies around him disappeared. Nothing unusual for bacteriologist Price in this was - fungal spores often entered the air in bacterial cultures and formed colonies. And Fleming saw this conventional picture something new is what he observed during his research - colonies of bacteria disappeared not themselves, their pathogenic cocci destroy fungi. This was done first on the road to great discovery.

laboratory studies were small victories and fails, much time

passed until it received its first industrial penicillin. Fleming stopped all other work and devoted all his time to study the properties penitsylium notatum and its relatives. If previously for lysozyme scientist forced all posters and collected tears, he now surprised that collected various moldy objects.

began his work with penitsylium notatum. During all these decades has not diminished, but rather increased the interest of researchers to antibiotics and other fungi. The result of this painstaking work is new antibiotics derived from fungi. Case Fleming continues!
