by the emergence of Shiga toxin-producing Escherichia coli (Callaway et al.‚ 2013). Specifically‚ Shiga toxin-producing E. coli O157 is a foodborne pathogen of significant public health importance. It can cause mild to bloody diarrhea in humans which may progress to hemolytic uremic syndrome (Centers for Disease Control and Prevention‚ 1993; Hussein‚ 2007) that can be fatal in children‚ the elderly and immunocompromised individuals. E. coli O157 is also responsible for an estimated 63‚153 illnesses

providers work more efficiently. One of these medical advancements would be a mutated E. coli. So how exactly can a mutated E. coli be an advancement? Well what scientist recently discovered is that this certain mutated bacteria actually will color urine to help diagnose medical diseases. So perhaps this mutated E. coli can make diagnosing certain issues a quicker process than before. One disease this E. coli mutant helps diagnose is diabetes. To elaborate on how this altered bacteria works

An Ode to E. Coli There is a natural human tendency to dismiss what we cannot see. This idea is based in evolutionary biology. Throughout most of human history‚ threats to our survival have been deadly predators . It is only natural then‚ that we should focus our concern on objects whose importance we can see. For this reason bacteria seem insignificant on the surface‚ its invisibility marking its lack of precedence as a threat. This is a misconception‚ because bacteria hold enormous power. It can

Student Lab Section 6 E. Coli Genetic Transformation with pGLO Plasmid Introduction: Genetic transformation is where one organism takes on a characteristic from another organism (Bacterial Transformation 2013). For this experiment we used the bacteria E. Coli to take in foreign jellyfish DNA which will allow it to change genetic material. This experiment determines the effects that the plasmid pGLO has in transferring the Green Florescent Protein found in a jellyfish into the bacteria. It

Title: E. Coli Transformation with a Plasmid DNA Containing the GFP Gene Introduction: Bacterial transformation is the process of bacteria taking in and expressing exogenous DNA. This has led to many other discoveries. In order for bacterial transformation to occur the bacteria must be in a certain physical state to be able to take in DNA. This is called competency and it allows the cell membrane to be permeable so DNA can pass through. Currently researchers are studying the transformation
