Antibiotics have played a major role in our society thanks to Sir Alexander Fleming's careful observations in 1928. Without it, many lives would be in danger due to infectious diseases. Antibiotics are chemical substances produced by various species of microorganisms and other living systems that are capable in small concentrations of inhibiting the growth of or killing bacteria and other microorganisms. These organisms can be bacteria, viruses, fungi, or animals called protozoa. A particular
Antibiotics An antibiotic, is defined to be a drug produced by certain microbes. Most doctors use antibiotics to help fight the germs in a patient. Antibiotics are obtained from plants, fungi, air, water, soil, just about anything on earth. Antibiotics kill and attack the germ or virus in the body, but do not hurt the human cells, ordinarily. The antibiotics are used to treat many various types of diseases, such as tuberculosis, syphilis, and several kinds of infections. People have been using
Antibiotics have been vital tools in the fight against bacterial infections, however their effectiveness has waned in recent times due to the advent of antibiotic resistant strains of bacteria. According to a review by P, the uses of antibiotics, as well as influences from the environment have allowed such bacterial strains to respond to changes in their environment rapidly, and so develop resistance. This acquired ability can have serious and broad implications in the medical field, evident in
the sub-therapeutic use of antibiotics in animal feeds is that “super-bugs” are able to evolve. This is a threat to both the health of the animals and humans. What a “super-bug” refers to is a strain of bacteria that has evolved to be resistant to bacteria and lethal to the host organism. These super-bugs account for the death of roughly 48,000 Americans each year (Adams, 2013). These superbugs proliferate in the digestive tracts of hosts. Each dose of antibiotics in the animals’ diets at sub-therapeutic
More information; Antibiotics are powerful substances which are capable of inhibiting bacterial growth. Antibiotics can be consumed from any part of the body. Essentially there are two different types of antibiotics which perform different operations to the body. (Medical News, 1) The first discovered type is bactericidal, which not only inhibits but initially eliminates the bacterial or microbial organisms, this is done through exterminating the bacterium cell wall which furthermore erupts and causes
stubbornly resistant pathogenic bacteria towards antibiotics. Diseases can be defeated or endured, if they are embraced. Denied or feared, they can grow and make it drudgery for scientists to manage. For years, South African mortality rates have escalated due to the phenomenon of antibiotic resistance. Antibiotic resistance is a consequence of the misuse of antibiotics that give pathogenic bacteria the ability to withstand the effects of an antibiotic. Resistance occurs when bacteria change in such
part in human history. Since 1877 the knowledge of antibiotics has expanded greatly. Antibiotics are constantly needed and new developments are crucial to human society. This topic should be known by all humans because antibiotics can be the difference of life and death. This industry and it’s success alters the health of many humans. Things like polio, chicken pox and measles are no longer taking lives. As new sicknesses form we need new antibiotics to counteract the new sicknesses. If we allow the
Thesis: With the advent of antibiotics in 1929 Fleming said, "The time may come when penicillin can be bought by anyone in the shops.Then there is the danger that the ignorant man may easily underdose himself and by exposing his microbes to non-lethal quantities of the drug make them resistant."With the overuse of antibiotics today we have seen this very idea come to be.Over usage is caused most prevalently by a lack of education on the part of the patient.Thus stated, the way to overcome such a
ANTIBIOTIC RESISTANCE IS A BIG PROBLEM. HOW CAN WE REDUCE IT? The Problem Antibiotics have been vitally important for many years in treating infectious diseases in both, humans and animals. Their discovery was described as the miracle of the 20th century [1]. However the overuse of antibiotics caused the emergence of a new problem, antibiotic resistance. Antibiotics completely changed medical care in the 1940s. It has also saved many lives over the years. The most important role of antibiotics is
What is an antibiotic? An antibiotic is a medication that weakens or even eliminates microorganisms that are causing an illness. An antibiotic is used to treat some bacterial diseases and infections. Antibiotics are made up of very strong synthetic drugs, natural materials or a combination of both. (https://www.cdc.gov/antibiotic-use/community/about/antibiotic-resistance-faqs.html) Antibiotics have been around for many decades and have been linked to a drastic decline in illness and death from infections
Antibiotics Throughout history disease has run rampant taking many lives with every passing day. Finding a cure or even just a tool in the battle has been the main focus of scientist throughout time. This focus is what brought us the discovery of antibiotics. Over the years antibiotics have been misused by patients, over prescribed by physicians and have led to resistant strains of bacteria. Resistant strains are no joke, for years my mother has been dealing with MRSA (methicillin-resistant staphylococcus
with bacteria that are resistant to antibiotics and at least twenty-three thousand people die each year as a direct result of these infections.” (Threat Report 2013) Antibiotics were created to kill bacteria; since they were created, the bacteria have started to become resistant to the antibiotics. Antibiotic resistance is the ability of a microorganism to withstand the effects of an antibiotic. Because of this resistance, I believe that the use of antibiotics have been proven to be more harmful
. Many doctors and patients are unaware that antibiotics are designed to treat bacterial infections, not viral infections (Antibiotic resistance, N.D.). Many bacteria within our bodies are not harmful at all, and some of them actually provide health benefits. The bacteria that are harmful are disease-causing bacteria, which generate sicknesses such as strep throat, the common cold, and ear infections (Get, 2013). Viruses are smaller than bacteria and require hosts, such as plants or animals, in order
“Misuse of antibiotics could result in selection for resistant bacteria”. This gentle warning mentioned by the inventor of antibiotics, Sir Alexander Fleming, seems to have lost its meaning over the course of years. Antimicrobial resistance is a growing public health concern; antibiotics used in factory farmed animals raised for human consumption contributes to this problem. Scientific evidence confirms that by the consumption of meat that contains antibiotic-resistant microbes, some antibiotic resistant
population, passing on their mutation to some of their offspring, until all organisms carry that mutation (often after several generations. The above occurrence has lead to some bacteria becoming resistant to some forms of antibiotics (aka antibiotic resistant bacteria). Antibiotics were first discovered by Professor Alexander Fleming in 1928 by accident when cleaning up his laboratory. This coincidental discovery lead to Fleming and many other scientists changing society and medicine and the way people
increasingly dependant on antibiotics to fight off the bacteria that cause diseases in our bodies. Many of the diseases these bacteria and microbes cause are infectious. For these reasons, it has been noticed that bacteria and other microbes are becoming increasingly resistant to the antibiotics prescribed to sick people. Many doctors prescribe antibiotics for common illnesses, yet other medicines such as home remedies and homeopathy could be used instead. As a result, we are using antibiotics too often, as
Antibiotics is one of the most effective weapons that the human race has against bacterial infections, as antibiotic treatments can clear an infection within a three to eight day period. However, the constant use of antibiotics has allowed bacteria to mutate their DNA, making them more resistant against the drug. Many scientist theorize that this resistance pattern will lead to a superbug, a bacterium strain that is resistant to possibly all antibiotics. That kind of disease could be catastrophic
Antibiotics are at times necessary in the treatment of bacterial infections. Since the discovery of penicillin by Alexander Fleming in 1928, antibiotics have been used to treat many diseases as a common practice by physicians and practitioners. The over-prescribing of antibiotics has put the patient’s health at risk with the growing trend of antibiotic resistant organisms. Antibiotic resistance has now become a universal problem which needs to be faced head on by healthcare workers. Healthcare
ANTIBIOTICS:- Antibiotics are medicines that fight bacteria. Antibiotics can save lives, if used properly. Antibiotics either kill bacteria or keep them from multiplying. Antibiotics do not fight virus infections. For example: Cold Flu ANTIBIOTICS: Most coughs Sore throats (Exception: strep throats) If you use antibiotics against viruses you will get more harmed than helped. When you take antibiotics, you need to follow the
The discovery of antibiotics in the 20th century was a major advancement in medicine. At the time of the discovery, war was taking place, which resulted in a plethora of infected wounds. Antibiotics can be described as a use, laboratory effect, or an action of a chemical compound (Clardy et al). Selman Waksman first used the term in 1941 when describing the small molecules made by microorganisms that prevent the growth of other microorganisms (Clardy et al). Antibiotics helped control the infection
