Identification of bacteria for micro.pptx
Traditional phenotypic methods and newer genotypic methods can both be used to identify bacteria. Phenotypic methods include gram staining, culturing, and analyzing biochemical characteristics and reactions. These methods have limitations as some bacteria cannot be cultured. Genotypic methods like MALDI-TOF, PCR, and microarrays identify bacteria based on their genetic material and can identify bacteria directly from clinical samples faster than phenotypic methods. A variety of biochemical tests are used as part of phenotypic identification to analyze carbohydrate metabolism, production of specific compounds, enzyme activity, and other characteristics.

Molecular taxonomy
Taxonomy is the branch of science concerned with the classification of organisms. A taxonomic designation is more than just a name. Ideally, it reflects evolutionary history and the relationship between organisms. Traditionally, taxonomic classification has relied upon morphological features and physiological characteristics. However, for bacterial taxonomy, phenotypic approaches have proven insufficient. Unrelated bacteria can exhibit identical traits, closely related bacteria can have divergent features, and methods for accurate identification may be too cumbersome for routine use. In contrast, molecular taxonomy approaches use data derived from hereditary material and provide a robust view of genetic relatedness. Advances in technology have been accompanied by improvements in the cost, speed, and availability of molecular methods. Here, we provide a brief history of approaches to prokaryotic classification and describe how molecular taxonomy is redefining our understanding of bacterial evolution and the tree of life.

Commercial genotypic methods like AccuProbe, MicroSEQ, and Riboprinter are also overviewed, along with their advantages and limitations compared to phenotypic identification methods. Overall genotypic methods are highlighted as being more accurate and precise than traditional techniques.
