Bacteriophage therapy and application of phages for biocontrol necessitate acquisition of suitable phages. The exclusivity of phage–host relations and the risk of phage resistance instigate a need to rapidly isolate and characterize novel phages and continually build sizeable phage libraries. Current methods for phage isolation are both laborious and time consuming, suitable for the isolation of a limited number of phages. The high-throughput screening method for phages upscales and organizes enrichment of phages for fast isolation and identification of potentially hundreds of distinct phages against single hosts. This enables screening of hundreds of samples, in multiple simultaneous setups with varying parameters, increasing the likelihood of isolating multiple distinct phages specific for the given conditions. The efficiency of the method is emphasized by our screening of 200 environmental samples, resulting in the identification of an abundance of unique phage species virulent to Escherichia coli, Salmonella enterica, Enterococcus faecalis, and Pseudomonas aeruginosa.
