Shigella Introduction: Shigella is a very infectious bacteria that causes Shigellosis. I. Morphology of Shigella • Gram-negative • Nonmotile bacillus II. 4 different species of Shigella • S. dysenteriae o Most severe type of shigellosis because it secretes Shiga Toxin Shiga toxin- stops protein synthesis in host’s cell. • S. flexneri o Is the predominate species in developing countries. • S. boydii • S. sonnei o Is the most common species isolated in industrialized nations.

questions. 1.)what are the symptoms of shigellosis? 2.)which ways can you get Shigellosis? 3.)what are the preventive measures you can take to avoid it? 4.)what treatments work for shigellosis? 5.)what foods have been commonly associated with shigella.? In my research the most concerning thing that I found was how easy it is to contract this disease through such careless behaviors as simple as not washing your hands or unclean environmentdrop my paper you will learn commonalities

for a barium xray and colonoscopy. While utilizing the methods stated above‚ the bacterium found was a facultative anaerobe due to the Gram Negative Rods‚ fermentation‚ and the production of indole. The specific Gram Negative Enteric Bacilli was Shigella dysenteriae. There are many reasons for knowing how to control bacterial growth as well as such as antimicrobial drugs‚ which assist the body’s defenses against pathogens. Microorganisms are capable of causing infection or spoilage. Controlling bacterial

CHM1032L pre/post lab instructions Preparation is a key to success in this lab. For this reason‚ you are required to thoroughly read through the experiment information presented in the lab manual‚ and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab‚ I will not allow you to enter the lab and you will receive

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical
