Third week of Microbiology class :)

Hello everyone!
For this week, we have started a new topic that is, Microscopy. 

This topic is about microscope and what kind of microscope is suitable to use since not all microbes can be seen under the same type of microscope, right? The microscope helps us to get the magnified image of the sample and it gets to separate the details in the image. There are two types of microscope which is the light microscope that has varieties, such as:
                          - Bright-field microscope
                          - Confocal microscope
                          - Dark-field microscope
                          - Fluorescence microscope
                          - Phase-contrast microscope

There are also electron microscope that used a beam electron to produce the magnified image. For instance:
             - Scanning electron microscope (SEM)
             - Transmission electron microscope (TEM)
             - Electron cryotomography

Before using the microscope, we have to make a preparation for the specimen by making a staining to the specimen. We can use varieties of staining procedure such as:
               - Simple staining
               - Differential staining
                    -> Gram staining
                    -> Acid-fast staining
               - Special staining
                    -> Negative staining
                    -> Endospore staining
                    -> Flagella staining

This week, we also have a quiz on this topic. The question is about the types of microscope used based on the picture given. I managed to get 5 questions right out of 6 questions. 
Quiz 1
This topic is interesting as I could learn about the usage of the microscope properly and even though it's only in a picture shown by my lecturer, I feel excited to see the image of the microbe under the microscope.

That's all for this week. See you next time!
