Bacterial Growth on Public Restroom Toilet Seats vs. Bacterial Growth on Public Restroom Door Handles: A Microbiological Approach Jamie J. Larsen Undergraduate Student (Biology Concentration) Department of Biology Tennessee Technological University Cookeville, TN 38505 Introduction People have come to desire information that would tell them how to disinfect particular areas (Ojima et al 2002) No one has yet used uniform sampling conditions to derive bacterial count distributions (Ojima et al 2002) Introduction (cont’d) The accumulation of this data would lead to research that could contribute to the estimation of infection risks for communicable diseases (Ojima et al 2002) Introduction (cont’d) More background information to be added here… Objective/Hypothesis Objective – Determine which surface contains the most bacteria Hypothesis – Public restroom toilet seats will contain the most bacteria Null Hypothesis – Both the toilet seats and the door handles will contain the same amount of bacteria Methods and Materials Materials (Goss 2006) – Data Form – 10 agar plates (divided in half) – Sterilized cotton swabs – Gloves – Distilled Water – Permanent Marker (to label plates) Methods and Materials (cont’d) Methods (Goss 2006) – Swab toilet seats and door handles in ten public restroom sites – Clean one site with bathroom cleaner – Label/Streak agar plates – Incubate for 48 hours – Check growth, do colony counts, and analyze results using the t-test statistic – Repeat experiment Results Results to be added here… Pictures to be added here of agar plates with bacterial growth on them…comparing the toilet seats to the door handles… Discussion Discussion of results to be added here with references used in the introduction… Conclusions Main points of experiment to be added here…
