Purpose of this experiment was to determine E. coli strain variability between two people. Antibiotic resistance is a growing problem. Some of this is due to overuse of antibiotics in humans, but some of it is due to the use of antibiotics as growth promoters in foods of animals. A study published in the journal in Aug 2007 found that the rate of adaptive mutation in E.coli "on the order of 10-5 per genome per generation which is 1,000 times as high as previous estimates" a finding which may have significan
