I saw an interesting clip about cheek cells and bacteria that is always present in our mouth. Dr. Brett Finlay did an experiment and it showed high amount of bacteria that he found in his mouth. He took a toothpick and scraped it inside of his cheek and put it on a slice. Then, he gram stained it. When he looked through the microscope, he saw two things on the slide. Those two things were his bacteria and another thing that he saw was his mynophlora. Mynophlora is picked up when you are born, and you live with it until you die. It exists in people's mouth all the time. Its everywhere and it is completely normal. Why I chose this short time clip is because I did some cheek cell experiment in Microbiology lab in the beginning of the semester. Also, we learn a lot about microbes and bacteria in class. So, this clip was a good reminder of the things I learned in class.
