THE SUDDEN POP QUIZ (OHH NO!!!)



Assalamualaikum and hi everyone, today class we learn about the  new topic which is Microscopy. First of all the objective of this topic are that we will be able to identify and compare the use of dark field, bright field, phase contrast, fluorescent and electron microscopes. The other objective is that we able to describe the use of staining in microscopy. Below are image of microscopy with the lable.





In the class we also discuss about the skin pathogen which is skin disease. The cause of pimples are Propionibacterium acnes and Staphylococcus aureus .Cutibacterium (Propionibacterium) acnes is the relatively slow-growing, typically aerotolerant anaerobic, Gram-positive bacterium (rod) linked to the skin condition of acne. For more information about this you can visit this website Propionibacterium


Propionibacterium acnes

We also discuss about the type of microscope which are bright field, dark field, phase-contrast, electron microscope and fluorescence microscope.  We also learn about the dark field microscope that it can observe the internal structure of the microorganisms. For example Sporangium. Sporangium will lyse when mature and will released it zoospore. Zoospore is a fungi spore with a flagella. The function of flagella is that zoospore to be able to move in rumen fluid. 


Sporangium


We also discuss about biofilms, it is a layer of microbe that stick to wet surfaces. It resistance to antibiotic and mainly found at teeth. Other than that, we learn about EPEC interacting with HeLa cells. It is of the microbial interaction. EPEC stands for Enteropathogenic Escerichia coli it is a diarheal pathogen of young child found in the intestines. HeLa cell is a immortal cell line that preserved and it is the the oldest and commonly used human cell line.

 After we finish the lecture Dr, Wan give us a POP QUIZ. Which it related to microscopy but we haven't discuss it yet with Dr Wan. The sudden quiz make everyone in the class shock but fortunately Dr. Wan just want to test our understanding and knowledge about this. So below is the mark that I got. Well I know it very bad but it is a first quiz and I need to improve myself more.





So that all for today, thank you for visited and read my blog. I will update more next week . Bye-bye. :)

THE FIRST EXPERIMENT

Image
             Hi everyone this blog is about the experiment or practical that i do with my group members. This blog will contain all the conclusion or summary of the experiment and also as reflection and the things that i newly found out. So last  Tuesday, my member and I do practical ambout the CULTURE TRANSFER TECHNIQUE. Which is that we just learn the technique of culturing and how to prevent it from contamination.              Above are the procedure on how to culturing. We got to transfer into three media which is  S. marcescens, broth culture "A" and broth culture "B". It transfer into  slant to broth transfer, broth to slant transfer and slant to agar deep transfer.          After we subculture it we wait for the next day to observe the results. The next day,  the result is observe below are the result that I obtain. S. marcescens to Nutrient Agar Deep S. marcescens  to Nutrient Broth S. marcescens  to Nutrient Agar Slant Broth culture "A" to Nutrien

First week in Microbiology class

Image
First day of class Microbiology (13/9/2017)            It is the first day class of microbiology. I'm slightly nervous and excited of what will we going through today. As our lecturer Dr. Wan came, she briefly introduces herself and she started to ask us question. She also told us to make 9 group which contain in a group 1 Malaysia. I'm in a group of 5 people. She throw a few question to us about microorganisms and the group of microorganisms. I feel flustered when suddenly Dr. Wan just ask us question without we learn anything but she said that it is her own ways to teach us which is the "Ask question style". She also said that once we go inside the the room, we also going inside the microbiology world.                    On that day, we also learn about the biggest bacteria in the world. It is Thimargarita namibiensis.  Is a gram negative coccoid Proteobacterium, found in ocean sediments of the contenential shelf of Namibia (Source: Wikipedi

Measurement & Motility of Microorganisms

Image
Hi and welcome to my blog. so our last practical class we did the experiment of measurement of microorganisms and the examination of microorganisms using hanging drop and wet mount.  The  hanging drop technique  is a well-established method for examining living, unstained, very small organisms. The traditional procedure employs a glass slide with a circular concavity in the centre into which a  drop  of fluid, containing the 'microorganisms', hangs from a coverslip. Meanwhile for   In a  wet mount , the specimen is placed in a drop of water or other liquid held between the slide and the cover slip by surface tension. This method is commonly used, for example, to view microscopic organisms that grow in pond water or other liquid media, especially when studying their movement and behavior. preparation of hanging-drop Preparing wet mount Meanwhile for the practical of measurement of microorganisms, we need ocular micrometer and stage micrometer. first we need to find the calibrati
