Question

Help answer this question below.

When I was in undergrad Biology, we did a lab where we tested all the surfaces of the public restroom to find the one covered with the most bacteria. Any guesses as to which surface it was?

    The sinks have the most bacteria, because people wash them off there and it is a moist area in which bacteria can survive for longer periods of time.

    we did this in my school a while ago and the places with the most bacteris were the coin slots in the vending machines and the stair banister. Also the computer keyboard was pretty disgusting.

    When I was an undergrad, we did a very similar test... we checked different surfaces in the building, but did not stick to the bathroom. It was an extra credit assignment, so I don't think anyone put too much thought into what to test.

    We found that water fountains had the highest counts, followed by doors. The hall floors were surprisingly clean... better than the chalkboard, actually.

    Probably the sink - bacteria tend to thrive on wet surfaces.
