The Relationship between Different Antibiotics, Vancomycin and Chloramphenicol with the bacteria,Staphylococcus aureus Cooper, Dalton and Alison Kim HC59 BOX1422 Cabins, WV 26855 Abstract During this experiment we observed which antibiotic, Vancomycin or Chloramphenicol will be most effective in controlling the growth of Staphylococcus aureus. The hypothesis that we tested was that both Vancomycin and Chloramphenicol will be effective in controlling the growth of S. aureus bacteria. Next we placed a disc in each disc, one containing Vancomycin, one containing Chloramphenicol, and one containing nothing in their respective dishes which we replicated eight times. We waited twenty-four hours for the cultures to develop and then refrigerated them for seventy-two more hours until we could collect the results. The mean death zone was +/- one standard deviation for the control was 0 +/- 0mm, for Chloramphenicol it was 26.25 +/- 1.39mm, and for Vancomycin it was 19.125 +/- .83mm. Chloramphenicol produced a significantly larger death zone than Vancomycin against S. aureus. After interpreting the data we have determined that our data supports our hypothesis that both would be effective, however, Chloramphenicol had a significantly larger death zone than Vancomycin. Introduction In this experiment, we tested Chloramphenicol and Vancomycin, which are both antibiotics that are used to kill bacteria in humans. In our tests we used the bacteria S. aureus and tried to determine which antibiotic, Chloramphenicol or Vancomycin would be more effective in killing the bacteria. We hypothesized that both antibiotics will be effective at controlling S. aureus; however after doing the experiment we determined which one is more effective than the other. Staphylococcus aureus, according to Todar (2005) is a Gram-positive spherical bacterium that occurs in microscopic
