10-5-10 Classification of Microbes Taxonomy- way of classifying organisms Taxa Domains Phylums Class Order Family Genus, species Carrolous Linneaus Scientific name (binomial nomenclature) Morphouar= morphology (shape) Brovars= physiolologs and biochemistry Erological= interaction Serovars=Serology=antigen interactions -All above involve phenotypes in general way Genetic/Molecular aspects=involve genotypes In classification systems, we can look at things in one or two ways: -Phenetic: how are things looking? -Phylogenetic (Phyletic): uses DNA or RNA to determine evolutionary relationships When dealing with Phenetics: Similarity Matrix which uses similarity coefficient =a/a+b+c -a= something both organisms have in common -b= something that’s present in organism 1 but not 2
