The Advent of Penicillin

Emergence of penicillin The emergence of penicillin has greatly changed the findings of the medical community, has the ability to treat diseases, is deadly then, is now considered common and easy to treat. Because antibiotics are one of the most prescribed medicines in the world today, penicillin is one of the greatest discoveries of the 20th century. Its discovery is often described as a coincidence, but its cultivation process is very detailed, and further development of penicillin is continually drawing attention.

Several developments in the early twentieth century improved the prognosis of patients with pneumonia. Due to the emergence of penicillin and other antibiotics in the 20th century, modern surgical techniques and intensive care, the pneumonia mortality rate has reached nearly 30%, which is falling sharply in developed countries. Infant vaccination against H. influenzae type B began in 1988, and the number of cases rapidly decreased immediately. Adult vaccination against S. pneumoniae began in 1977 and children caused a similar decline in 2000

Penicillin (PCN or pen) is a group of antibiotics including penicillin G (for intravenous use), penicillin V (for oral use), procaine penicillin and benzathine penicillin (intramuscular use). Penicillin antibiotics are the first to be effective against bacterial infections caused by staphylococci and streptococci. Though they are widely used today, many types of bacteria have demonstrated resistance after extensive use. Penicillin was discovered by Scottish scientist Alexander Fleming in 1928. It was used in the treatment of infectious diseases in 1942. There are several enhanced penicillin families that are effective against other bacteria; they include anti-staphylococcal penicillin, aminopenicillin, and anti-Pseudomonas penicillin. They are derived from Penicillium

Penicillin is being developed as an antibiotic. In 1928, British bacteriologist Alexander Fleming (1881-1955) discovered the bactericidal properties of penicillin. Fleming pointed out that fungus that accidentally fell into the bacterial culture in his laboratory killed the bacteria. After identifying mold as fungus Penicillium notatum, Fleming used it to make juice and named it penicillin. After handing it to the experimental mouse, he discovered that it could kill mouse bacteria without harming healthy somatic cells. Fleming found an incredible finding, but he was unable to produce penicillin in a useful form for the doctor.

When Alexander Fleming first discovered it in 1928, the antibiotic penicillin was welcomed as a miracle medicine as it blocked the bacteria that caused the infection. In the next few years, penicillin has been developed as a medicine for humans and livestock, and dead infection can be treated with normal injections or pills. Life expectancy increased, infant mortality rate declined. Thirty thousand Americans died of bacterial diseases in 1930 and less than 95,000 people died in the same disease despite the fact that the population increased nearly 30% in 1952.
