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

Purpose: To identify an unknown bacterial specimen using basic laboratory technique and biochemical tests. The unknown bacteria will be one of the following: Enterococcus faecalis‚ Staphylococcus saprophyticus‚ Escherichia coli‚ Enterobacter aerogenes‚ Proteus vulgaris‚ Salmonella [I assume typhimurium]‚ or Shigella [either flexneri or sonnei‚ we used both in our lab during the semester]. Procedure {and observations}: Observe bacterial colony morphology. {Colonies are large‚ beige or

Unknown Lab Report #1 Unknown #1 April 25‚ 2012 Microbiology Spring 2012 MCB2010C Unknown #1 Introduction Identity of a microorganism has proven to be very significant. Doing so can help identify diseases and created treatment and cures for such diseases. As a result‚ various laboratory tests were performed to an unknown microbe (Unknown #1) found in the water of a nearby pond. By identify the microbe‚ the safety of the water will be known to those around it. Materials and Methods

Requirements for Unknown Report You have been provided a mixed culture (a gram positive and a gram negative) from which you should have isolated each type of organism‚ described their colonies on a TSA plate‚ and described their cellular morphology. You were graded on this activity separately. After you have isolated your gram negative in pure culture you will be subjecting it to various biochemical tests and making observations about the cells‚ colonies‚ growth temperature preferences‚ etc. in
