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

bacteria. Those tiny living creatures are remarkably intricate. Witnessing the breathtaking phenomena created by marine microbes strengthened my determination to further pursue my study of marine microbiology. In my first year as an undergraduate student I participated in lab work on marine microbiology. I led one project on separation and identification of pigment-containing bacteria in the Xiamen Coastal Areas‚

learned so far in the microbiology laboratory class for the identification of unknown bacteria. The identification process can be completed with a series of deferential stains and biochemical tests. Creating a dichotomous key helps to limit the amount of biochemical tests done on an unknown organism and by observation and recording of data the unknown organism can be found. Materials and Methods The procedure for all tests performed was taken from Leboffe and Pierce’s Microbiology: Laboratory Theory

explained through science. I have always been fascinated to know how things work and why or how they happen. That is why microbiology is perfect for me. I like finding out how or why something can happen and I can do that if I go into the field of science. I have been looking into colleges and professions recently and I have become very interested in microbiology. Microbiology is the study of microorganisms. Microbiologists try to understand the organisms and how they interact with their

Negative macroscopic screened urines do not routinely require microscopic examination of urine sediment. Microscopic examination of urine sediment may be warranted when macroscopic examination is positive for blood (Hb)‚ protein (greater than a trace)‚ nitrite

TRIPLE SUGAR-IRON AGAR TEST Triple sugar-iron (TSI) agar test- designed to differentiate among the different groups or genera of the Enterobacteriaceae‚ which are all gram-negative bacilli capable of fermenting glucose with the production of acid a. Differentiation is made on the basis of differences in carbohydrate fermentation patterns and hydrogen sulfide production. To facilitate observation of carbohydrate utilization patterns- TSI agar slants contain lactose and sucrose (1%) concentrations
