This week we looked at our slides through the microscope. We found similar data as our last gram staining test. They appeared red in color, indicating that they're gram negative bacteria. Their shape was also rounded. Some appeared to be short rods, while others were more circular. The last time we gram stained it took me a moment to really identify what I was looking at. But Matt and Josh helped us better understand that some may be in a skewed position. Sort of like looking at a pencil from the eraser end, you miss all the other details of its shape. Because of the morphology we noted, we went with bacilli.
The image below is of one of the colonies. First thing you will note is the red color and we had to take a closer look for the shape.
Hopefully more test can help us
better identify the bacteria.
Doing the Unknown Bacteria lab was quite interesting, it was fun trying to understand how to execute this lab. Even though it had nothing to do with my degree, but it was fun. Identifying the bacteria was the hard part because it was hard to tell what shape they were.
ReplyDeleteOoh wow. Your bacteria looks really pretty. Looking at bacteria under the microscope used to be so hard for me but it got really easy especially after taking Microbiology with Dr. Cotter. The real struggle for me was taking a pic of it haha. You are doing great so far. Keep up the good work!
