摘要

The experiment evaluates the effect of changes in indoor environment on the number of colonies of Staphylococcus epidermidis. Staphylococcus epidermidis is found in human skin, and it can result in serious illnesses. The research question is ‘What is the effect of frequency of usage in addition to temperature on the number of Staphylococcusudepidermidis colonies in which the samples were taken from a desk by the windowsill, a desk in the middle of the classroom and a desk near the door that are examined in theudmedical laboratory?’ The samples were taken from the windowsill desk, desk in the middle of the classroom anduddesk near the window to observe changes in the number of colonies according to the frequency of usage and temperature. The number of colonies was counted in the laboratory by using sample cultivation, gram staining and differentiation. Five trials were conducted andudthe mean values were calculated to increase the accuracy of the results.udThe results of the experiment illustrated that the highest mean value of the Staphylococcus epidermidis colonies is found in the desk in the middle of the classroom, which has the highest temperature and also people come into most contact with that desk. The lowest mean value of the Staphylococcus epidermidis is found in the desk by the windowsill, which has the lowest temperature and people come into least contact with it.
