You have been given several bacterial strains from various countries around the world. It is thought that all the strains cause the same gastrointestinal illness and are genetically identical. After carrying out a DNA finger print analysis of the strains, you find that 4 different strain types are present. How would you know this based on your finger print results? Explain. Explain how you could use DNA-DNA hybridization and multilocus sequence typing to determine id these 4 strains would belong to the same species. Would you be able to use a G-C ratio to determine if they were the same species? Why/why not? Explain.
