ABSTRACT
The functional characterization of "hypothetical" phage genes is a major bottleneck in basic and applied phage research. To compound this issue, the most suitable phages for therapeutic applications-the strictly lytic variety-are largely recalcitrant to classical genetic techniques due to low recombination rates and lack of selectable markers. Here we describe methods for fast and effective phage engineering that rely upon a Type III-A CRISPR-Cas system. In these methods, the CRISPR-Cas system is used as a powerful counterselection tool to isolate rare phage recombinants.
