ABSTRACT In todays world of ever evolving genetic mutations the incidence of drug resistant forms of microorganisms are on the rise. The importance of identifying these pathogens and their related epidemiology has become increasingly more important. The purpose of this study was to identify an unknown bacterium in a controlled laboratory environment over a 5 week period. Utilizing a variety of differential testing and staining methods learned in the microbiology course‚ students were to determine

1. Make sure you label both plates on the bottom‚ with your name‚ date and name of pathogen you have chosen (listed above under materials) Then label numbers 1-5 on one plate and 6-10 on the other as there are 10 disks that need to be placed. Spread out in a circle formation like pictured below (This is the final product; look at this for reference on how to label) Now you are ready to start culturing. Start with one of your plates you can do both at the same time but to avoid making any errors

Unknown Lab Report Unknown Organism #6 Ann Le (Phuoc) May 6‚ 2010 Dr. Carrington Microbiology Lab- MW 12:50 Le 1 I. Introduction My unknown organism #6 is Morganella morganii‚ which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans‚ mammals‚ and reptiles as a normal flora. (3‚ 5) This bacterium Morganella morganii‚ was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide

called volcanology. Divergent plate boundaries: At the mid-oceanic ridges‚ two tectonic plates diverge from one another. New oceanic crust is being formed by hot molten rock slowly cooling and solidifying. The crust is very thin at mid-oceanic ridges due to the pull of the tectonic plates. The release of pressure due to the thinning of the crust leads to adiabatic expansion‚ and the partial melting of the mantle causing volcanism and creating new oceanic crust. Most divergent plate boundaries are at the

Knights in Medieval Europe Knights were the most advanced fighting unit of the Middle Ages. Developed mainly by Charles Martel‚ they were horsemen‚ armored and carrying swords. By definition‚ a Knight was a mounted warrior in the service of his liege-lord (Snell‚ "Defining the Knight"‚ Knight Life‚ Internet). He they would generally receive a fief in exchange for their services. But Knights also became important as a symbol of honor‚ nobility (in the moral sense of the word)‚ and loyalty towards

What scientific data was used to support the theory of continental drift? Identify and explain at least four pieces of evidence. 4. What were the problems with the original theory of continental drift? 5. How does the presence of ocean ridges and trenches support the theory that the continents move?

John Wilson discovered the Theory of Plate Tectonics. He contributed himself to the development of the Plate Tectonics Theory in 1963. The theory that made this important to this development‚ was The Theory of Continental Drift. To develop or prove his Theory he gathered info from other scientists like Alfred Wegener‚ Harry Hess‚ Eduard Suess‚ and more. Alfred Wegener proved that the plates could move‚ but he couldn’t develop the source that moved them. Harry Hess discovered the process of Seafloor
