Abstract

An object of the present invention is to provide a recombinant phage having high safety and excellent practicality and usefulness. Provided are a recombinant bacteriophage which is deprived of its proliferative capacity and can infect only once due to the fact that a bacteriophage genome in which a part of a virion constituent gene is deleted is stored in a head, and a method for preparing the same. In addition, provided are a recombinant bacteriophage which is deprived of its proliferative capacity and can infect only once due to the fact that a plasmid having a packaging site and encoding a target gene is stored in a head, and a method for preparing the same.
