The native microbiome of the nematode C. elegans. a–c Frequency spectra of the bacterial classes based on MiSeq genotyping analysis for C. elegans (a), C. remanei (b), and C. briggsae (c), including results for natural worms (single worms), lab-enriched worms (nematode populations), and the corresponding substrates. d Differential interference contrast micrograph of C. elegans inhabited by its native microbiome. The anterior end of the worm is to the left. e–g Ordination by canonical correspondence analysis of bacterial operational taxonomic unit abundance in natural Caenorhabditis isolates and their substrates from German and French locations (indicated by colors and symbols; see legend), showing the three most significant axes. A three-dimensional visualization is given in Additional file 2. Statistics are provided in Additional file 1: Tables S1-6, S1-7, and S1-8. Detailed information about the samples is provided in Additional file 1: Tables S1-1 and S1-2. See also Additional file 3
