BOX 1-1 Role of Taxonomy in Diagnostic Microbiology and Infectious Diseases
Establishes and maintains records of key characteristics of clinically relevant microorganisms
Facilitates communication among technologists, microbiologists, physicians, and scientists by assigning universally useful names to clinically relevant microorganisms. This is essential for:
- Establishing an association of particular diseases or syndromes with specific microorganisms
- Accumulating knowledge regarding the management and outcome of diseases associated with specific microorganisms ■ Establishing patterns of resistance to antimicrobial agents and recognition of changing microbial resistance patterns
- Understanding the mechanisms of antimicrobial resistance and detecting new resistance mechanisms exhibited by a particular microorganism
- Recognizing new and emerging pathogenic microorganisms
- Recognizing changes in the types of infections or diseases caused by familiar microorganisms
- Designing alterations of available technologies for the development of new methods that optimize the detection and Identification ot infectious agents and optimize detection of microbial resistance to antlinfective agents
- Developing new antiinfective therapies components are always used simultaneously and are printed in italics, or underlined in script. For example, the streptococci include Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agaladiae, Streptococcus bovis, among others. Alternatively, the name may be abbreviated by using the upper case form of the first letter of the genus designation followed by a period (.) and the full species name, which is never abbreviated, such as S. pneumoniae, S. pyogenes, S. agaladiae, and S. bovis. Frequently an informal designation (e.g., staphylococci, streptococci, enterococd) may be used to label a particular group of organisms, but such designations are not capitalized or italicized.
As more information is gained regarding organism classification and identification, a particular species may be moved to a different genus or assigned a new genus name. The rules and criteria for these changes are beyond the scope of this chapter, but such changes are documented in the International Journal for Systematic Bacteriology. In the diagnostic laboratory, changes in nomenclature are phased in gradually so that physicians and laboratorians have ample opportunity to recognize that a familiar pathogen has been given a new name. This is usually accomplished by using the new genus designation while continuing to provide the previous designation in parentheses, for example, Stenotro-phomonas (Xanthomonas) maltophilia or Burkholderia (Pseudomonas) cepacia.
