KRONA diagram showing the revised taxonomy assignments produced using MEGAN followed by identification of conserved domains for the 557 viruses found in this study. The majority of virus contigs were most closely related to (+)ssRNA viruses, particularly members of the Picornavirales, as well as tombus-like and noda-like viruses. There were also a number of ssDNA viruses, including CRESS viruses and members of the Parvoviridae. Groups representing <0.7% of all viruses are collapsed and depicted with cross-hatch shading.
