Unlocking Bacteriophage Potential

PrecisionPhage is a Finland-based biotech company specializing in phage technologies.

We provide bioinformatic analyses, phage licensing and laboratory services.


What are bacteriophages?

...or 'phages' for short

Phages are viruses that attack bacteria

They are natural predators of bacteria – and can be used to combat infections.
  • Precision. Unlike antibiotics, phages only attack their target bacteria
  • Diversity. There is likely a phage for every bacterium out there, even for the antibiotic-resistant ones
  • Flexibility and evolvability. Phages can be combined to a "phage cocktail" against which bacterial resistance is less likely to develop. Phages can also be evolved to target a specific bacterial strain.

Products and services

We offer computational and laboratory-based phage services



Analyse phage genomes swiftly and accurately with our cloud-based, user-friendly software.

  • Genome assembly. Submit your raw sequencing reads to our automated assembly pipeline.

  • Genome analysis. Analyse your newly assembled phage genome for its suitability for phage therapy or other purposes. Alternatively, submit your own assembly.

  • Comparative genomics True analytical power comes from comparison. Compare phage attributes and create heatmaps, alignments and other comparative genomic analyses in the browser.

Phage collection

We have been building a phage collection for more than ten years, now spanning over 1,500 strains.

The main targets of the collection include, but are not limited to:
  • Escherichia coli

  • Klebsiella pneumoniae

  • Pseudomonas aeruginosa

  • Acinetobacter baumannii

We can screen your bacterium against our collection to find suitable phages for your purpose
Our phages are available for exclusive or non-exclusive licensing

Phage laboratory services

Our Finland-based, state-of-the-art laboratory is equipped to provide a range of phage services, including:

  • On-demand phage isolation ?

    If there is no compatible phage in our collection, we can always go phage hunting for you! The isolated phages can be licensed or purchased based on the established contracts. At the moment this service is limited to bacterial species and strains of biosafety-level (BSL) 2 (or below) bacteria. For a substantial number of BSL3 strains, we offer options for developmental cooperation.

  • Small-scale phage production
  • Sequencing
  • Customised genomic analyses
