For our sample we took swabs of our hands. My sample on one half and Rose's on the other half. To obtain this sample we had to first dip the swab in a saline solution, because the sample from our hands would be dry.
Once we each smeared our half of the nutrient agar plate we each chose two different antibacterial products to test out.
I chose to test mouth wash and hand sanitizer.
While Rose tested Lysol wipes and Clorox bleach spray.
We soaked little discs in theses multiple solutions so we could set them in the separate sections of our nutrient agar plate.
In order to pick up the different discs we used forceps. To sterilize them we first ran them through the flame of the bunsen burner, then we dipped the tips of them in 70% ethanol alcohol.
We then incubated our sample at 37 degrees centigrade, because that is the temperature of the human body and our hands where we obtained our sample. Next class we would see which antibacterial agents worked the best.
When we returned back to lab we found that all of the bacteria that were on our hands are able to be easily killed simply by washing their hands or by disinfecting the surface with Clorox bleach or Lysol wipes. However, if we try to wash our hands with mouthwash it is not as effective.
So wash your hands frequently and make sure to clean surfaces with disinfecting agents!!!
Thanks for sharing this post about the swab testing for microbiological testing......
ReplyDeleteSwab test is provided to determine conformity with the specifications given in the individual monograph / specifications. Swab analyze is the keeping track of count of aerobic viruses, yeasts and molds on any surface.
