Abstract: In lab, we were given the broth of an unknown bacteria labeled with simply a number. The purpose of this experiment, is to use the techniques previously acquired during the course of the lab in order to identify the unknown. The unknown presented will be one of three gram-negative bacteria: Escherichia coli, Klebsiella pneumoniae, or Salmonella typhimurium. The streak plate technique and Gram Staining methods were completed in order to obtain colonies and to identify the morphology of the
viral fever syndrome, dengue fever, fever hemorrhagic fever or dengue shock syndrome. (World Health Organization 2003) The disease is often, though not exclusively, closely associated with poor environmental sanitation, inferior housing and inadequate water supplies. Communities where such conditions prevail must be told what step they should take to prevent and control DHF. The diagnosis and management of
