Introduction: Resistance to antibiotics is an ongoing concern of the pharmaceutical industry. The limited number of antibiotics in the market to treat Gram negative bacteria made their resistance an issue that is being addressed worldwide. The isolation of colistin from Bacillus polymyxa var. colistinus in Japan in 1949 and the introduction of colistin into the market in 1959 as its inactive prodrug colistin methanesulfonate (CMS) were significant milestones in the treatment of this type of…

This paper explores antibiotic resistance along with the issues that can play a portion in preventing it. It talks about healthcare facility along with staff being cautious not to spread the virus between patients. In turn it discuss what people can do to prepare themselves in order not to catch viruses or spread them either. Making sure that healthcare works are changing proper equipment after each patient. Lastly it considers how the role of antimicrobial sensitivity plays in cutting…

The Semmelweis Reflex In 2017, it is common knowledge that bacteria live inside of corpses, and that bacteria can cause diseases. Almost every elementary schooler is fully aware of this fact. Nevertheless, at one point this was a groundbreaking discovery, one that was met with great skepticism and mockery. The German-Hungarian physician Ignaz Semmelweis (July 1, 1818 – August 13, 1865) is credited with the discovery of what is now common sense: one should wash their hands between handling dead…

The increase in antibiotic resistant bacteria is a substantial issue in the medical world today and is one of the greatest threats to the survival of the human species. Many bacterial infections that were once treatable with antibiotics are becoming increasingly untreatable, due to the bacteria being overexposed to antibiotics and consequently developing resistances to them. The use of antibiotics agriculturally in livestock and with veterinarians with pets are also factors in the increase…

Polio When the topic polio is brought up, most people have very little knowledge about it. Some have heard that Franklin D. Roosevelt had it. Some even know that you can be paralyzed from. But, most only know the basic facts. Polio was a disease that spread all through the United States in the 1950s and 1960s crippling, paralyzing, and killing many people and also played a role in many novels including Blue by Joyce Moyer Hostetter, The Big Dipper Marathon by Jerome Brooks, and Close to Home by…

You “…avoid eye contact with the mutants, unsuccessfully ignoring the suppurating wounds that consume their bodies and bulging sangria-coloured veins that lather their crimson skin like vines.” Hello, I’m Darcy Smith, an Australian author, and today I am going to explain the scientific concepts behind my short story, ‘The Changing’ in the hope of being considered for the 2016 Anthology of Science Fiction Stories by Australian authors. Set only a few years from the present, my story portrays a…

None of us are ever really alone. That’s because at any given moment in the day, our gut is alive with tens of trillions – tens of TRILLIONS – of microorganisms that make up what is called our gut microbiota, or gut flora. These trillions of microorganisms include at least 1000 different species of known bacteria that contain more than 3 million genes. To put this into a bit of perspective, that’s 150 times more than human genes! What’s particularly interesting is that while one third of our gut…

Throughout all of history humans have been trying to find new and more efficient cures. Often times these cures are based on observations of natural elements. I choose the article, Researchers Find Antimicrobial Substances in Komodo Dragon Blood from the George Mason University, because I was interested by what made their blood special compared to other creatures. The article analyzed why Komodo dragons are resistant to the bacteria found in their saliva, which is used to kill prey. Researchers…

Velocity of Bacteria and Cells Determine the Need of Antibiotics The first goal was to examine the motion of E. coli bacteria. Excel was used to analyze and record the position, velocity and acceleration of the bacteria. The second goal was to analyze and compare the cell motion of wound healing, neutrophils and E.coli bacteria using ImageJ to determine if a patient needs to take antibiotics to cure his injury based on the velocity of E. coli, neutrophils, and wound healing. Experimental…

Edgar Allan Poe’s death is a very controversial topic. No doubt about it. When it's brought up in conversation, many people begin to argue. Last week, our class held a Socratic Seminar about this topic. And I believe that what I chose to talk about was the right decision, and how I knew it was. During the Seminar, I brought up the theory of cooping, thinking it would be the right thing thing to do. Just in case you don't know, Cooping is a form of kidnaping the involves drugging someone,…
