Overview on the radiological, toxicological, and microbiological characteristics of the ACB mummy. A Computed tomography (CT)-based three-dimensional reconstruction of the skull. Notice the darker colors which represent lower x-ray densities than healthy bone. Copyright: Holger Wittig, Institute of Forensic Medicine, University of Basel. B Concentration of elemental mercury in different body samples, where the error bars refer to the standard errors. C Relative abundances of the top 12 microbial families on different body tissues as inferred by number of shotgun-metagenomic reads compared against the nr-database (please refer to the “Methods” section for details). Numbers in parentheses refer to sample IDs (please refer to Additional file 1: Table S1 for further details)
