What Are The Key Discoveries In The 1920's

Antibiotics were a pivotal discovery which saved many lives during epidemics and pandemics over the recent centuries. During the 1920’s a scientist named Alexander Fleming was working as the professor of bacteriology in London at St. Mary's Hospital. Alexander was working on staphylococcus and had left some on the table which got contaminated. Later a colony was spotted in one of the samples resembling a white fluffy mass which multiplied rapidly and caused the staphylococcus to become transparent. Weeks later the bacteria had exhibited antibacterial properties and was especially effective on pathogenic strains. This would urge fleming to bring this to other universities and further research.
In 1925 Fleming published his work in the British journal of pathology where he talked about its abilities to kill bacteria that cause strep throat and other pathogens. The article had led Oxford university to start research on the substance. Researchers at Oxford were working on the purification of penicillin and had turned the raw substance into a life saving drug. The continued research of penicillin made increased amounts of refined product to be produced. Making 500 litres a week, the researchers had started to refine penicillin for clinical trials.

These places are full of bacteria and hosts. The hosts are usually pigs and cows that are kept in close quarters. These animals are given antibiotics whenever they are fed regardless of the health. This causes harmless bacteria to become completely antibiotic resistant. While they are resistant the meat of the animal still contains high amounts of antibiotics that remain in the meat even after they are cooked. Since humans are host for many harmless and harmful bacteria, eating antibiotic infused eat is harmful since the bacteria will become resistant and can spread that resistance to other species of
