To the Editor: Advanced molecular biologic methods have improved the species differentiation and taxonomic classification of microorganisms, including nontuberculous mycobacteria. Taxonomic classification establishes stability of nomenclature through the aegis of a formalized and universally accepted language that facilitates transmission of knowledge across time and the barriers of natural language. The sequences are compared to a validated library for positive identification and taxonomic classifications. |
