Table 2. Overlaps in host prokaryotes.
| Data source | # hosts | % overlap with other data sources* |
|---|---|---|
| ICTV | 11 | 100% |
| ‘Earth's virome’ project (44) | 1247 | 79.4% |
| Predicted prophages from EMBL proGenomes database (41) | 2549 | 78.6% |
| Predicted prophages from NCBI complete genomes (40) | 4398 | 68.18% |
| Predicted prophages in human gut (1,42) | 210 | 67.61% |
| NCBI reference viral genome database (39) | 282 | 56.73% |
| Predicted viral and prophage sequences from complete and draft genomes (36) | 6388 | 56.6% |
* the overlap ratio is defined as proportion of hosts in a data source that could also found in any of the other data sources.
