Basically, Classification, Identification and Nomenclature of Microorganisms is quite similar with what I have learned in my first semester with Dr. Wan. There is only little differences in their content. From this chapter, I know how to write the bacteria's name in a correct way and I know how they obtain their names. Mitsuokella jalaludinii is a type of bacteria that is isolated from the rumens of cattle in Malaysia. It is in honour of S. Jalaludin, an animal nutritionist and Vice-Chancellor of Universiti Putra Malaysia, who has contributed significantly to rumen microbiology.
There are different ways to describe strains within a species such as:
- Biovars - differ in biochemical and physiological
- Morphovars - differ in morphological
- Serovars - differ in distinctive antigenic properties
There are 3 ways in classification system and they are include phenetic (numerical taxonomy and dendogram), phylogenetic (16S rRNA and phylogenetic tree) and genotypic (other molecular method). For the rest of the content I have summarised them in 2 mindmaps :)
But Dr. Sieo told us that the mindmap is quite incorrect. The methods of Identification and Classification is can only be divided into classical and molecular. The picture below might give you a clearer picture from this topic.

IMMUNOLOGY
What is immune system? It is a defense system of the individual against the threat of disease cause by infectious microorganisms. Immunology is quite complicated because they have to eliminate the pathogen without damaging the host. Basically, there are 2 types of lymphoid organs (primary and secondary).
Primary :
- Bone marrow
- Bursa of Fabricius (for bird)
- Thymus
- Adenoid
- Tonsils
- Lymph nodes
- Spleen
- Mucosa-assiociated Lymphoid Tissue (MALT)
Immunity can be divided into specific and non-specific. There are 2 types of non-specific immunity include,
INTERNAL
- Physiological (fever)
- Inflammation
- Phagocytosis
- Skin
- Mucous membranes
- Normal microbiota
Specific immunity can be either humoral or cell-mediated immunity. Picture below is the immune response toward pathogen that we drew on the whiteboard. Like Dr Sieo told us, "This chapter is like a snowball rolling from the top of a mountain or hill, its getting bigger and bigger. Once you don't understand from the beginning, its getting really hard for the rest of the chapter".
