Microbiology Semester 2 Week 6

         Assalamualaikum and hi everyone... how are you all? I hope everyone will be fine as well... On Tuesday,  Dr Suriana taught us about the introduction to prokaryote systematic. Basically, Prokaryote systematics is a highly dynamic science in which the concepts rapidly change in accordance with the development of new techniques and approaches. Systematics is generally signifies a broader concept that includes the evolutionary and phylogenetic relationships of the organisms studied but but taxonomy is can be subdivided into three disciplines which are classification, nomenclature, and identification. The classification provided in Bergey’s Manual of Systematic Bacteriology is widely used among microbiologists, but was never intended to obtain official status. Nomenclature is subject to changes in accordance to new insights which is species have been renamed, moved to other existing genera, or reclassified in newly established genera. Identification is the practical use of classification and nomenclature to determine the identity of an isolate as a member of an established taxon or as a member of a previously unidentified species. Type strain is the “nomenclatural type of the species”, and is the "reference point" to which all other strains are compared to know whether they belong to that species.

        Ribotyping is identification method based on the fragmentation pattern when the genomic DNA is cut by specific restriction enzymes the fragments separated by electrophoresis, and then hybridized with a probe specific for 16S rRNA genes. On Friday, we went to IBS (Institusi Biotechnology Science) to learnt about the culture collection. On Friday, they was briefing about the culture collection. Next week, my group was learnt about culture collection in more detail. That's all for this week microbiology class.
