PhageDive is a specific database for bacteriophages and archaeal viruses. Built on the BacDive model, it gathers and links all the experimental data and metadata (e.g., geographical origin, isolation source) of the viruses present in different culture collections (Laval collection, NCTC, DSMZ). Its implementation aims to facilitate access to all viruses information for the scientific community. The database covers taxonomy, host strain, phage morphology, life cycle, origin and genomic data. PhageDive offers an Advanced search allowing queries such as "show me all phages infecting this strain" or "show me all viruses with this enzyme".
