The oral cavity contains diverse bacteria species. A shift in the oral microbiota diversity is associated with both local and systemic diseases. Among these are difficult to treat periodontal diseases and cancers. Bacteriophages can provide a means to manipulate the microbiota in the oral cavity. However, to date, there have only been a limited number of bacteriophages specific to oral bacteria that have been characterised. Some bacteria carry bacteriophages in their genomes and so provide a resource for isolating these temperate bacteriophages, referred to as prophages. The prophages provide a platform for isolation and characterisation of lysis proteins that may be utilised as antimicrobials. In this study, we screened for prophages from the oral pathogenic bacteria Solobacterium moorei and Porphyromonas gingivalis. We report characterisation of the first ever bacteriophage for S. moorei, SMO_1P. The genome of SMO_1P was analysed and screened for lytic enzymes, which potentially could be cloned, expressed as recombinant protein, and tested for capacity to manipulate the oral microbiome.
