In-Silico Phage Characterization & Biosafety Verification

Deterministic genomic screening for bacteriophage therapeutics

Automated multi-tool genomic audit evaluating contig completeness, strictly virulent lytic compliance, absence of antimicrobial resistance, non-toxigenic virulome profiling, and target bacterial host interaction — producing publication-ready clinical dossiers.

Screening modules & safety checkpoints

01 > QUALITY CONTROL & BOUNDARIES

CheckV Contig Screening

Verifies complete circular terminal repeats, assesses host contamination percentage, and ensures candidate length satisfies the therapeutic 20–700 kb window.

02 > STRUCTURAL & 3D FOLD ANNOTATION

pharokka & phold (ProstT5)

Combines fast HMM gene prediction with 3D structural protein language models to resolve unknown hypothetical proteins, baseplates, and tail fibers.

03 > SAFETY & DEFENSE SCREENING

CARD, RGI, VFDB & AcrFinder

Enforces zero-tolerance safety screening for transmissible antibiotic resistance determinants, bacterial exotoxins, and anti-CRISPR genetic elements.

04 > LIFESTYLE & HOST PREDICTION

BACPHLIP & PHIEmbed

Classifies virulent lytic vs temperate lysogenic lifestyles, checks for absence of integrases/recombinases, and predicts high-affinity bacterial host targets.
