My Encounter 2


This week I encountered microbiology before my very eyes in the girls bathroom of Wilkinson Hall.  It was a Wednesday evening and I am just getting out from working at the school bookstore.  After I close, I usually go to the restroom just to wash my hands because for the past 3 and half hours I was touching and handling money.  I like washing my hands after work because that's also the time that I decide to have dinner in the cafe.

It was to my dismay that as I walk into the bathroom, a female exited a stall after flushing the toilet without washing her hands.  I was disgusted as she touched the handle of the door that I potentially could have touched right after her if I had not seen what she did.  I began to think about the different bacteria that now existed on that door handle as I continued on to wash my hands.  While drying my hands, I made a conscience decision not to touch that handle bar and use another paper towel as a barrier.  If I did not make that decision I am positive that I would be coming down with some kind of sickness as of now.

This relates to Microbiology class because bacteria exist everywhere.  This class teaches us of the various types of bacteria that exist, some good and some bad.  After being in that bathroom that day, I'm positive that there was nothing but bad bacteria all over that door handle.  I began to remember how in class we talked about different ways of preventing the spread of pathogenic microorganisms through proper sanitation, disinfection, or even sterilizing objects.
