Bacteriophages as biocontrol agents of food pathogens. In this regard, Joerger notes that the use of phage therapy necessarily requires a high MOI, meaning a greater phage titer compared with the titer of its target bacterium. This includes, for instance, T4 gene uvsX [22] which specifies a protein that has three-dimensional structural homology to RecA from Escherichia coli and the homologous protein RAD51 in eukaryotes and RadA in archaea.
