Second, some strains exhibit unique biochemical characteristics that do not fit into patterns that have been used as a characteristic of any known genus and species. In the past decade or so, molecular techniques have proven beneficial in overcoming some limitations of traditional phenotypic procedures for the detection and characterization of bacterial phenotypes. Several non-culture based methods have emerged in the past 15 years. Real time PCR and microarrays are currently the most commonly employed molecular techniques.
Real time PCR is highly sensitive and allows quantitation of bacteria at a species level. Microarray based bacterial identification relies on the hybridization of preamplified bacterial DNA sequences to arrayed species-specific oligonucleotides. In many distinct areas of microbiology, the ability to identify microorganisms has important application. For example, in food microbiology it is important to be able to accurately identify food spoilage contaminants.
In microbial ecology, the identification of microorganisms helps us characterize biodiversity. In the field of medical microbiology, a branch of microbiology that investigates pathogenic microorganisms, the primary focus is to isolate, identify, and study microorganisms responsible for infectious disease.
