The Viral Host Range database (VHRdb) represents a unique resource for the community to rapidly find, document analyze and disseminate data related to the range of hosts that a virus can infect. Over the years, countless host range experiments have been performed in many laboratories. However, these data are not readily available to the community and are therefore underexploited.

The VHRdb is an online resource that centralizes experimental data related to the host range of viruses. While it originates from bacteriophages and bacteria interaction studies, its design is compatible with viruses infecting all living forms. Users can browse publicly available data to find which host is infected by a virus, and vice versa. Users can also upload their own data, with the option to keep it private or make it public, analyze results across independent sets of data, generate and visualize outputs. Data implemented in the VHRdb are linked to users and, if available, to publications and sequence identifiers.

The VHRdb is an initiative from the Debarbieux lab and is developed and maintained in collaboration with the Bioinformatics and Biostatistics Hub of Institut Pasteur.


Curators help maintaining a coherent naming scheme among the public data sources. For more information on what a curator can and cannot do or see, please check the documentation.
