[Chinese expert consensus for nomenclature, isolation and detection of bacterial extracellular vesicles].

Bacterial extracellular vesicles (BEVs), considered to mediate interactions between bacteria, and bacteria-host interactions, play a crucial role in the development and progression of diseases. However, there is currently no unified standard for the nomenclature, isolation, and detection of BEVs. Consequently, inconsistencies are observed in the results of related research, preventing a more comprehensive and objective analysis of BEVs. Therefore, it is imperative to establish an expert consensus based on fundamental research methods for the nomenclature, isolation, and detection of BEVs to facilitate their clinical translation and applications. This consensus statement was written by a working group composed of experienced experts in the fields of medical diagnostics, microbiology, and materials biology. It provides an overview of commonly used techniques and basic methods for the isolation and detection of BEVs. The statement offers recommendations and considerations to improve the feasibility and reproducibility of BEVs research, emphasizing pivotal issues and challenges in the transition of BEVs towards clinical applications, with the aim of serving as a reference for subsequent studies.
