An important aim of Swiss Biobanking Platform is to promote exchange and use of biological samples. Researchers need to be able to assess the suitability of samples for their planned application. Relevant sample data need thus to be documented by the biobanks in a standardized way. Defining the essential data linked to samples supports the goal of improving the quality of samples, making samples from different biobanks comparable and searchable (interoperability), promoting their exchange and enhancing visibility. To this end, the SBP Working Group Microbiology proposes – as a first step – a dataset for bacteria, recommended to be used by all biobanks.
