Microbiology is a field of science which typically is divided into several areas such as: bacteriology‚ virology‚ parasitology and immunology. The goal of microbiology is to increase the specific knowledge of a known microorganism and by extension counter the spread of harmful microorganisms and to learn practical applications of research results. A microbiologist studies the structure‚ metabolism‚ genetics and ecology of microorganisms such as bacteria‚ viruses‚ fungi or algae. A microbiologist

Unknown reports in microbiology are written in scientific format. Scientific writing is written differently from other types of writing. The results of the exercise or experiment are what are being showcased‚ not the writing. The purpose of scientific writing is not to entertain‚ but to inform. The writing should be simple and easy to understand. There is a specific style that must be followed when writing scientific reports. Scientific writing is typically written in the passive voice. The

Staphylococcus aureus is found as normal part of the skin floral in the nasal passages and on the skin. An estimated twenty percent of people naturally have harmless Staphylococcus aureus on their skin and are long-term carries for Staphylococcus aureus. Staphylococcus aureus is the most common strand of Staphylococcus in humans to date

sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and to subsequently utilize those techniques for the purpose of identifying the bacteria

MIC 230 Unknown Identification Report The objective of this experiment was to identify an organism from a mixture of two unknown bacterial species. In order to accomplish this‚ I first plated my unknown mixture on Tryptic Soy Agar (TSA)‚ Columbia Naladixic Acid (CNA)‚ and MacConkey’s Agar (MAC) plates. After 48 hours of incubation‚ it was unclear that two different bacterial colonies had grown on my TSA plate. Only one type of colony was evident. However‚ it was apparent that I had successfully

Microbiology is involved in many aspects of human daily life. The food eaten to the showerheads in the bathroom contain thousands of microbes. Microbiology is evident in our lives and it is reported through various media. News reports have articles about microbes just like a recent article from Times Magazine titled Overcoming Obesity by Alex Park. Park featured article is about the problem of obesity in America and how different scientists are thinking of new manners to combat this epidemic

H1N1: The Sneaky Killer I chose to write my topic paper on the H1N1 virus. This virus has interested me since its reemergence in 2009. Its ability to change and adapt each time it shows up again attracted my attention. I hope to inform people about the virus along with the symptoms and how to go about avoiding it if you can‚ or treating it if you have it. This pandemic is avoidable through a simple vaccine that can be taken as a shot or as a nasal spray. Overall I find the H1N1 virus to be interesting

My unknown turned out to be gram positive bacteria cocci shaped with long chain cell arrangement. The unknown was gram positive because the cells stained blue-violet ‚this indicate that my unknown has ability to retain crystal violet-iodine after alcohol application on the cells which is a gram
