[WEEK1-WEEK7]
Salam ‘alaik and good
morning Dr. Wan !
It have been a long
time that I'm not updated my blog since week 14 last sem. So, today I
want to summarized what I've learn for a half of semester with Dr. Seow Chin
Chin.
She is a good
lecturer! For the half of the semester, she only teach us two chapters of
Microbiology II that are Microbial Taxonomy and Immunology.
As for
me, Microbial Taxonomy is quite easy as we have learnt the
three parts of taxonomy that are nomenclature,
classification and identification.
We learnt how to name the
microbes and established it in a legal way for nomenclature. This is a part of microbial taxonomy in Microbiology
I. the basic in Microbiology I, we have detailed in this semester. We learnt the two type of
Bergey’s Manual that is systematic and determinative. We also have to do our
first assignment on week 1 that was we have to find the two types of Bergey’s
Manual at Sultan Abdul Samad Library and have to have a look on what the
contents, we also have to take a picture of the book cover of Bergey’s Manual
and submitted it in Edmodo.
Besides, we learnt about classification have three ways that are
; Phenetic, Phylogenetic and Genotypic. We also learnt technique to get a
strain of bacteria and how to isolate the DNA. Next for this chapter, we have learnt
the technique for determining microbial taxonomy and phylogeny are divided into
two that are ; classical characteristic and molecular characteristics.
For the last
part of Microbial Taxonomy was identification.
In this part we have learnt the identification methods are :
1)
Microscopic
examination
2)
Growth and
biochemical characteristic
3)
Immunologic
test’
4)
Bacteriophage
typing
5)
Antibiotic
susceptibility test
6)
Molecular methods
For the
molecular methods we had learnt in classification, for this part we just learnt
about the nucleic acid probes and plasmid fingerprinting.
At the end
of this chapter we were having our fabulous Test 1! And Alhamdulillah, I’m
satisfied with my result even though it was not as excellent as Radin’s result.

Next chapter
was Immunology. I think this chapter was hard to understand. But Dr Chin Chin had
tried her best to make us understand one by one in this chapter.
In this
chapter we learnt the two types of Immunity that were non-specific immunity and specific
immunity.
In non-specific immunity it has internal innate immunity and external innate immunity. For the
internal innate immunity there were three mechanisms of protection that are physiological
barrier, phagocytosis and inflammation. Besides,
for the external innate immunity it prevent penetration of pathogens into
tissue such as skin, mucous membranes and normal microbiota.
In the specific immunity we have humoral immunity and cell-mediated immunity. In the humoral immunity we learnt how
antibodies give protection to us, the antigen binding sites will bind to the
epitopes to function to give protection through neutralization, agglutination, opsonisation,
activation of complement and ADCC. Next, in cell-mediated immunity we learnt the granule exocytosis and Fas
pathway in CD8 T cell mechanisms. We also covered the last part of immunology
that was DTH reaction.
We were
having our quiz on the last lecture with Dr Chin Chin on Immunology! And our
group was the first runner up! And for Test 2 on 29th June is on
Immunology. Pray for us to get good a result Dr Wan!
Till we meet
again, thankyou! J
