Microorganism

population’s growth rate under normal conditions. Notably, microbes possess some of the greatest biotic potentials as compared to large mammals. Today, Microbiology has largely human welfare and health following their understanding the role these microorganisms in agriculture and food (Xu, 2010). Further, population evolution is a vital factor in devising important strategies for the protection, conservation and even maintenance of enhanced utilization of useful microbes. If this does not…

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…

The purpose of the infections caused by gram-positive cocci lab exercise is to utilize different identification and diagnostic techniques to differentiate various groups of bacteria, which cause infection. Our primary goal is first to establish the presence of an infection; then, determine which particular pathogens, or groups of pathogens, are the underlying cause of the infection. In the clinic, infections manifesting from gram-positive cocci are a common and growing problem. Two genera in…

Introduction: Bacteria and Fungi are important contributors of the living life. They however differ in their colony/ color/ size/shape/appearance. Bacteria are generally small in size but large in colonial structure, they are usually in the form of coccus, bacillus and spirillum, many times bacteria are of vivid colors because they have chlorophyll which also absorbs the light of different wavelengths which create natural colors of brown, pink, blue, orange and purple. Fungi on the other…

It is rare to find someone that is a master of their trade, but when it came to saving lives through disease research Louis Pasteur is one. Throughout his entire life he stayed around educational institutions and universities. His career was very long and consisted of lots of research and much time spent in laboratories. Described as a man who would do anything for his trade, at times he was even said to put his life at risk to do his research. Countless lives have been saved due to Pasteur’s…

Francisella tularensis is an important microbial agent which causes the severe infection of tularemia. The intracellular life cycle of this bacterium is supported by a vast range of protective guards such as enzymes. Although several enzymes are recognized in different subspecies of the bacterium, acid phosphatase and superoxide dismutase are seen in all bacterial subspecies. On the other hand, the most important enzymatic system relating to host cells is NADPH oxidase. For this reason, the…

*SCENE 1 : Calgene Lab* Scientist A: According to my research, once I perform this experiment, it will interfere with the production of the protein that causes the decay. Scientist A: I just need to do this and..*stomach grumbles*...nope. I need to go to the restroom for a bit. What this scientist didn't know is that his son was watching from afar. Son: Oooooh, a needle. But why is the tomato the only one left with no needles? Son: Let me fix that. The son then sticks the needle to the…

The chesapeake Bay is a bay located in the harbor between Virginia and Delaware on the east coast of the United States. Many big factories and many large chicken farms, and several other large corporations are based either right on the bay, or not far from it. Many of the large corporations based out there include Purdue Farms, Chesapeake Energy Corp. and many more. All of these corporations have a lot of pollution and many other factors. Many pollution factors include chicken manure, smoke from…

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…

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…
