Antibacterial proteins inhibiting have been identified in various phages and explored as antibiotic alternatives. Here, we isolated a phiKZ-like phage, Churi, which encodes 364 open reading frames. We examined 15 early-expressed phage proteins for their ability to inhibit bacterial growth, and found that gp335, closely related to phiKZ-gp14, exhibits antibacterial activity.

Chimalliviridae phages encapsulate their genomes in a nucleus-like replication compartment composed of the protein chimallin (ChmA) that excludes ribosomes and decouples transcription from translation. These phages selectively partition proteins between the phage nucleus and the bacterial cytoplasm.

However, bacteria may acquire phage resistance quickly, limiting the use of phage treatment. The combination of genetically diverse phages displaying distinct replication machinery in phage cocktails has therefore become a novel strategy to improve therapeutic outcomes.

Bacteriophages or phages, which are viruses that specifically kill bacteria, have been considered as alternative agents for the treatment of bacterial infections. Here, we discovered a lytic phage targeting , designated as JJ01, which was classified as a member of the family due to the presence of an icosahedral capsid and a contractile tail under TEM.
