Principles Of Phenotypebased Identification Schemes

As shown in Figure 7-13, growth characteristics, microscopic morphologies, and single test results are used to categorize most bacterial isolates into general groups. However, the definitive identification to species requires use of schemes designed to produce metabolic profiles of the organisms. Identification systems usually consist of four major components (Figure 7-17):

  • Selection and inoculation of a set (i.e., battery) of specific metabolic substrates and growth inhibitors
  • Incubation to allow substrate utilization to occur or to allow growth inhibitors to act
  • Determination of metabolic activity that occurred during incubation
  • Analysis of metabolic profiles and comparison with established profile databases for known bacterial species to establish definitive identification
