Recombinant bacteriophage and methods for their use

摘要

Recombinant P4 bacteriophage containing modified tail fibers having a base plate attachment region (BPAR) from a P2 bacteriophage gene H product and a heterologous receptor binding domain (RBD) are disclosed. Methods for the use of the recombinant P4 bacteriophage, such as to detect the presence of a target bacterium in a sample, are also described.
