The opportunities of research parasitism: A case study using the Barcode of Life Data System (BOLD)

Abstract

Abstract The Barcode of Life Data System (BOLD) is primarily used to identify biological specimens based on a mitochondrial gene sequence and has been an underpinning resource for life science researchers. Importantly, curators of BOLD archive DNA extracts where possible, and also record contaminant sequences that can be made available on request. This collegial offering of samples and data led to our work describing the serendipitous discovery of new interactions between a Torix Rickettsia bacterium and their arthropod hosts and resulted in winning the 2022 Junior Research Parasite Award. A case study of this work is presented, which discusses the opportunities provided by secondary data and how careful maintenance of such large-scale repositories plays a vital role in scientific research that goes beyond obvious lines of enquiry.
