RESISTANCE TO ANTIBIOTICS IS A BIG PROBLEM. HOW CAN WE REDUCE IT? The problem Antibiotics have been vitally important for many years in the treatment of infectious diseases in both humans and animals. Their discovery was described as the miracle of the 20th century [1]. However, the overuse of antibiotics has caused the emergence of a new problem, antibiotic resistance. In the 1940s, antibiotics completely changed medical care. It has also saved many lives over the years. The most important role of antibiotics is to treat a number of harmful diseases caused by bacteria, and during the early years antibiotics developed faster than bacteria developed resistance. Between the 1950s and 1960s, scientists managed to discover many new antibiotics, but in the 1980s and 1990s, scientists only managed to improve existing ones. A report from the Standing Medical Advisory Committee states that microorganisms are advancing and no more antibiotics are being discovered [2]. Bacteria usually live on and in all creatures. Not all bacteria are pathogenic (disease producing), in fact many are harmless. Pathogenic bacteria can cause very serious infections. Before antibiotics were discovered, many deaths occurred due to bacterial infections [1]. Penicillin was the first antibiotic discovered in 1928 by Alexander Fleming. He observed a series of culture plates used to grow staph. He saw that a mold was growing around the staph, producing a bacteria-free ring around itself. Two other scientists, Florey and Chain, developed penicillin into an effective drug. Penicillin has been tested for over 20 years on both humans and animals. In 1941 scientists noted that even low doses of penicillin produced prevented many deadly fields... middle of paper... medicine, healthcare, Internet technology, and business. It also contains a peer-reviewed editorial policy that allows it to be a reliable source. YouTube [16] is a popular website known worldwide by many people around the world. Reliability depends on the video chosen and who is hosting it. The video I chose is hosted by Dr. Karl Klose. Dr. Klose has a doctorate in microbiology from the University of California Berkeley and performed postdoctoral studies in microbial pathogenesis at Harvard Medical School. This means that it is not just any person talking about the problem; in fact he knows bacteria and has studied them. Dr. Klose may be a biased scientist, which would mean that he only speaks from his point of view. Searching other sources I noticed that what it said was found in other websites, so this source is reliable.
