INPHARED v2: Supplementary Tables for 28,777 Bacteriophage Genomes

INPHARED v2 provides curated metadata for 28,777 complete bacteriophage genomes from cultured isolates, representing an update from the 2021 release. The database includes genome quality assessments, lifestyle predictions, and annotations for defence and anti-defence systems. Author Ryan Cook published this snapshot on figshare in April 2026 under a CC-BY-4.0 license.

Use Cases

• Tracking changes in phage diversity over time based on the comparison of 2021 and 2026 database snapshots.
• Analyzing host bias and discovery trends based on the addition of 97 new host genera.
• Predicting phage lifestyle (e.g., lytic vs. lysogenic) using the incorporated lifestyle predictions.
• Studying phage-host interactions through the annotated defence and anti-defence systems.

Strengths

• Database size has approximately doubled from 14,244 to 28,777 genomes.
• Includes multiple annotation layers: genome quality, lifestyle predictions, and defence system annotations.
• Provides a temporal comparison spanning a five-year period that included a major taxonomy overhaul by the ICTV.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description notes that redundant sequencing is outpacing new discovery, indicating potential redundancy.
