Change of Plans: Overview of Bacterial Taxonomy, Recent Changes of Medical Importance, and Potential Areas of Impact

Abstract

Abstract The process of bacterial nomenclature change has evolved in complexity over time and continues to be an iterative process that is not without challenges. The importance and feasibility of such changes varies between basic researchers, clinical microbiologists, and clinicians. In recent years, clinically-relevant changes have been made across gram-positive and gram-negative organism groups, as well as the mycobacteria. Updated clinical laboratory accreditation requirements state that clinical laboratories must update their reporting practices in the case of clinically-relevant nomenclature changes. These updates may significantly impact various sectors of healthcare including antimicrobial stewardship, laboratory protocols, and infection prevention procedures and policies. While regularly updating bacterial nomenclature aims to improve the accuracy and consistency of our microbial language, the potential impact of such changes must be considered.
