Notes:
1) Taxonomy is the science of naming, describing and classifying organisms and includes all plants, animals and microorganisms in the world.
2) There are three interrelated parts in taxanomy:
- Classification : Arrangement of organisms into group based on mutual similarity or evolutionary relatedness.
- Nomenclature: The branch of taxonomy concerned with the assignment of names to taxonomic groups according to the published rules.
- Identification: The pprocess of determining that a particular isolate belongs to a recognized taxon.
3) The common rules for naming a microbes are both world underlined or italicized, genus name is always capitalized, species name is lowercase. For example: Vibrio cholerae
4) The process of naming a New bacteria :
a) Run scientific tests to verify the bacteria
b) Give a name to that bacteria
c) Publish the name of bacteria in International Journal of Systematic Bateriology
d) The bacteria will be deposited in culture collection bank
e) The description of bacteria will incorporated into Bergey's Manual
5) Strain means subgroup of species with one or more characteristics that distinguish it from other subgroup of the same species.
6) Strain can be identified by a name, number and letter follows by specific epithet.
7) Biovars are strains that differs biochemical or physiological with other strains in a particular species.
8) Morphovars are strains that differs morphological with other strains in a particular species.
9) Serovars are strains that differs antigenic properties with other strains in a particular species.
10) The naming of microbes normally inspired from the shape, place it found, nutrient it uses, the person discovered it and the disease it causes.
Activities: No activity carried out except for teaching...^^
My own Explorace:
1) Bergey's manual is the main source for identifying the bacteria species based on their every characteristic aspects.
2) Macroscopic observation means based on what you can see with your naked eye. For example, the shape, colour of the colony of microbes. Microscopic observation means you only can observe by using a microscope. For example, the colour and shape of the bacterium.
3) List our some bateria with different shapes:
- Coccus : Streptococcus pneumoniae, Streptococcus epidermidis
- Bacillus: Lactobacillus bulgaricus, Lactobacillus acidophilus, Bacillus anthracis
- Sarcina: Sarcina ventriculli
- Tetrad: Staphylococcus aureus
- Spiral: Treponema pallidum, Borrelia parkeri, Spirillum minus
- Comma: Vibrio cholerae, Vibrio vulnificus
Today lecture is quite short because it is just one hour lecture. When Dr asked us to name some bacteria with their different shape, I can't answer. I feel quite embarrassed because as a microbiology student at least shouldn't be blank for this question. I think more effort should put to study about the microbes.
