Antibiotic resistance

Heymann, and Weinberg, 2008). Due to increased antibiotic usage in modern medicine, MRSA is resistant to many antibiotics (“MRSA infection”, 2015). Scientists try to predict which antibiotics MRSA can develop…

penicillin, the world’s first antibiotic that would eventually save countless numbers of lives (“Discovery” par. 4). Since then, many new antibiotics have been introduced in the market; however, they are misused frequently, thus creating a shortage of effective antibiotics as bacteria develop resistance to overused antibiotics. Many people believe antibiotics…

Antibiotics I. Introduction 1. Attention Getter: “Fungi are the interface organisms between life and death” by Paul Stamets 2. Relation: How many of you used antibiotic during your life time? 3. Thesis: For many years the human population has benefited from antibiotics; however is still many are not education on antibiotics. 4. Preview: Today I inform you about the following information: History of antibiotics, how antibiotics are being used in the U.S, and the effects of over using.…

Professor Stuart B. Levy a physician from Tufts University affirms that the more antibiotics are used, the more resistance develops, demonstrating the fact that resistance is a product of evolution, and the more bacteria that are exposed to antimicrobials, the more will resistance be spread and…

Antibiotics How do you feel about antibiotics? Are they helpful or are they harmful, are they safe or are they dangerous? The current situation we are dealing with right now is should everyone have access to antibiotics in their homes. Today as of 2016 “antibiotics are life-saving drugs” (Dryden, M) but can be harmful if we don’t use them correctly. “Everyone prescribing antibiotics should consider both their clinical and public health responsibilities” (Dryden, M) because antibiotics…

dangerous for humans since antibiotics have the potential to create extremely deadly and resistant bacteria known as superbugs. In the early 1900’s it was discovered that penicillin effectively treated several kinds of infections but as soon as the drug was mass produced, in the span 20 years bacteria began to develop a resistance to penicillin (CDC). Because of results in cases like the mass production of penicillin the FDA tightened its rules creating limits in the use of antibiotics. But in…

evolution. Bacterial antibiotic evolution is the growing resistance to antibiotics through mutations in bacteria’s DNA. Vestigial organs are organs that are no longer needed in the body of an animals. Endogenous retroviruses are markers in DNA that show a point where a big change in a species has happened, and are passed on to offspring. Bacterial antibiotic evolution, vestigial organs,…

There are three main mechanisms through which bacteria can develop resistance against beta-lactams, namely,developing PBPs with lower affinity for beta-lactam, reducing access to PBPs, or developing enzymes which act against the antibiotics, known as beta-lactamases (Rice 2012). The first method,that of producing new PBPs is most common in gram-positive bacteria, such as Staphylococcus aureus, which produces PBP2a,or Enterococcus faecium, which produces PBP5 (Rice 2012). Gram-negative bacteria…

Antibiotic sensitivity is the susceptibility of bacteria to antibiotics. Susceptibility can vary within bacteria of the same species due to different strains; with some strains being more resistant than others. Antimicrobial resistance is the ability of a microorganism to survive and multiply in the presence of an antimicrobial agent that would normally inhibit or kill this species of microorganism. Antibiotic susceptibility tests are done in order to determine, which specific antimicrobials…

of is found in 1/3 of the human population and is causing quite a stir in the medical community because of it's growing resistance to many forms of antibiotics (CDC, 2016). This bacteria, nick-named a super bug, is known as Methicillin-resistant Staphylococcus aureus or MRSA, for short. First discovered in 1961, MRSA has grown significantly resistant to many forms of antibiotics at an alarming rate, and pharmaceutical companies, researching for new forms of medicine, are having a tough time…
