called accidental discoveries that have been key to the history of science would definitely not be complete without the next one, probably the most famous one of all time. Scottish bacteriologist Alexander Fleming was serving as the Professor of Bacteriology at the St. Mary's Hospital in London in 1928. He had just returned from the holidays when he immediately noticed something unusual as he sorted through his petri dishes that contained Staphylococcus. One dish had a blob of mold…
It must also be recalled that the founders of WHO, was activated for the benefit of its member state. Thus, the emphasis on prevention and direct control is not unexpected. At the same time, by 20th century the rising of germ theory and modern bacteriology were also affecting the institution in two ways (Scott 2015: 34). First, infectious disease outbreaks posed a direct threat to social contact between citizens and the government (Scott 2015: 34). If the government allowed the disease to rage…
In order to correctly identify each organism, a chart was created from Bergey’s Manual of Determinative Bacteriology that incorporated all known biochemical test results for each of the thirteen possible organisms. The thirteen organisms were separated into three separate categories, Gram-negative bacilli, Gram-positive bacilli, and Gram-positive cocci. This table can be found in the appendix (Bergey and Holt, 1994). Based on the information in the chart, the order of biochemical tests…
in which blood transfusions were practical.16 The last and most significant inventions are antibiotics. They are considered to be the miracle drug of the 20th century. Alexander Fleming invented penicillin in 1928.17 Fleming was a professor of bacteriology at St. Mary’s Hospital Medical School in London. He discovered bacteriolytic agents that destroyed the structures of certain bacteria. He called these agents lysozymes. This was the backbone of his research on penicillin. His discovery was…
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…
Hawaii Health System Corporation consists of more than 70 affiliation agreements with various educational institutions that provide training and residency programs for all health care professionals (Hawaii.gov, 2014). Hawaii Health System Corporation (HHSC) operates over 1,200 patient beds with more than 4,000 employees in facilities situated on five Hawaiian Islands (Hawaii.gov, 2014). Hawaii Health System Corporation facilities run a critical care hospital, community hospitals, long-term care,…
Medicine has been around since the 20th century and is still in use today. Antibiotics are a type of medicine that helps stop infections caused by bacteria. The first Antibiotic (Penicillin) was discovered by Alexander Fleming in 1928. Since the discovery of Penicillin many other antibiotics have been discovered. The development of antibiotics was an important innovation because it cured infections, treated patients during World War I with infections and burns that led to the development of…
Abstract: The objective of these series of experiments was to identify two unknown bacteria’s. Broth culture #20 was selected and subjected to qualitative tests for identification. Gram stain tests were performed in order to identify which unknown is gram positive and gram negative. Using selective and differential media, like MacConkey agar which allows the growth of gram negative bacteria only that are able to ferment lactose. Also, mannitol agar was used which isolates and detects…
People are not aware of the problems that are likely to cause an end to life as known. Antibiotic resistance is a life-threatening problem most choose to ignore. “Each year in the United States, at least two million people become infected with bacteria that are resistant to antibiotics,” says Centers for Disease Control and Prevention (2016). Doctors are prescribing antibiotics when they should not be used, or should use a weaker dose of that antibiotic. Before too long, the bacteria are going…
The idea of evolution was once taboo for its new ideas at the time, it was seen as wrong because it challenged ideas already established about the world, especially how life came to be. Evolution is a relatively new idea discovered by Charles Darwin. This discovery came to be when Darwin was traveling along the Galapagos islands where he studied finches and discovered that these finches had all originated from one species of finch and eventually became differentiated leading the species to split…
