Among the series of Abdul Wasay’s lectures on Microbiology, this lecture is specifically designed to explain The Microbial Taxonomy.
Natural and Phenetic Classification
At first, educator explains taxonomy. After that nomenclature and identification is discussed. Then natural classification is elaborated. In the end, phenetic classification is pursued.
Educator begins by discussing phylogenetic classification. Carl Woese and George Fox proposed phylogenetic classification using small subunit (SSU) rRNA nucleotide sequences. After that genotypic classification is highlighted. Following this, bacterial hierarchical arrangement in taxonomy is demonstrated.
Initially, educator talks about binomial system of Linnaeus in detail. Then discussion continues on microbial taxonomy and phylogeny. Alongside, its characteristics are elaborated.
Earlier in this section, educator elaborates nucleic acid base composition. Next, nucleic acid hybridization is focused. Following this, DNA- DNA hybridization is pursued. Subsequently, information about nucleic acid sequencing is conveyed.
At first, introduction of genomic fingerprinting is given. After that ribotyping is demonstrated. Then thorough explanation continues on phylogenetic trees. Moving onward, Bergey's manual of systematic bacteriology is covered in detail in this part.
