A new VMR is now available for MSL41.
A new version of the Virus Metadata Resource (VMR) spreadsheet (VMR_MSL41.v1.20260320.xlsx) has been released that updates the virus exemplar records for to coincide with the release of MSL41, the 2025-2026 taxonomy and Master Species List. This version, released on March 20, 2026, can be downloaded from https://ictv.global/vmr/current.
The VMR has also been archived on Zenodo with the DOI: 10.5281/zenodo.19154144
The ICTV chooses an exemplar virus for each species and the VMR provides a list of these exemplars. An exemplar virus serves as an example of a well-characterized virus isolate of that species and includes the GenBank accession number for the genomic sequence of the isolate as well as the virus name, isolate designation, suggested abbreviation, genome composition, and host source. For more information on the VMR, please see https://ictv.global/vmr.
