Antibiotics

Introduction Antibiotics are the natural substances produced by the microbes that destroy or slow down the growth of the bacteria, whereas antimicrobial agents are the synthetic substances which developed in the laboratory that mimic effects of antibiotics. Selective toxicity means the microbial agents that kill the microbes without killing the host cells. Antimicrobial is divided into two spectrum of antibiotics – 1 Narrow spectrum: - This antibiotic is active against a selected group of the…

“treating common infections becomes more difficult”. Right now the season is winter, and this is when we are most prone to biotic infections. Antibiotics “can cause more harm than good”. It risks us getting antibiotic-resistant in the future. In an article “pencrtration of brain abscess by systemically administered antibiotics” discuss the effect of antibiotics on the brain. This article is written by Perry Black, M.D. In his research he founded that the patients were “capable of penetrating the…

Many of you would’ve heard the word Antibiotic at least once in your life, a few of you may have even taken some. It’s a very well known medical term and literally means ‘life-killing’. Something I’m certain will astound you, is that growing resistance against these once revolutionary treatments is one of the biggest threats to global health today. For those who don’t know, Antibiotics are a branch of drugs that stop bacteria from reproducing. This is achieved by stopping vital processes…

This paper will discuss two different issues disinfectants and antimicrobial agent susceptibility testing/resistance. To better understand disinfectants we will further explore topics such as: the meaning of bactericidal, bacteriostatic, virucidal, and fungistatic; the importance of using a control culture when evaluating disinfectants; factors that can impact the activity of disinfectants; microorganism having different responses to disinfectants; and identifying the microorganism susceptible…

Penicillin was one of the first antibiotics created and used on the population. Sir Alexander Fleming changed the world of medicine not only in his days but also in present-day society. Penicillin was one of the greatest discoveries of the twentieth century, as antibiotics are one of the highest prescribed drugs in the world today. Penicillin is responsible for preventing the spread of infectious disease, and for improving military medicine. While revolutionizing the study of medicine,…

GENTAMICIN The drug selected for study is Gentamicin. Gentamicin is an aminoglycoside antibiotic composed of a mixture of related Gentamicin components and fractions and is used to treat many types of bacterial infections, particularly those caused by Gram-negative organisms. Isolation and Preliminary studies 2 demonstrated that it is a mixture of basic, water soluble antibiotic containing the aminocyclitol 2-deoxystreptamine and two additional amino sugars. Chromatographic separation of…

The antibiotic I’ve chosen to write about is Levofloxacin or more commonly known as Levaquin. Levaquin can also be named Quixin or Lquix. Levofloxin is a flucroquinolone which resides in the broad spectrum realm of antibiotics. Levofloxacin is used to treat many bacterial infection varying from the skin, sinuses, kidneys, bladder, and even the prostate. Levofloxacin can also be prescribed to individuals that have been subject to anthrax and or the plaque. More specifically and more commonly…

Germs are everywhere. Fortunately, most pose no risks to people. And those that do cause disease usually can be killed with antibiotic drugs. Sometimes, however, harmful bacteria evolve ways to “laugh at” antibiotics — survive as if the poisons were not even there. This so-called drug resistance make infections hard, if not impossible, to treat. How bacteria learn to resist killer drugs normally is invisible. But scientists have just unveiled a new tool that lets them watch it happen, right…

specific, are annoying, can't stop trending, and should not be tolerated with anymore. The only problem is they may actually be beneficial to science. Recent news has surfaced that there is certain bacteria in beards that can actually work as an antibiotic. As people know, many Brooklyn hipsters can be seen with beards, and unfortunately this may give the world a reason to keep them around. REASON 1: THE BROOKLYN HIPSTER'S BEARDS CAN HELP WITH SCIENCE Adam Roberts is the famous microbiologist…
