Abstract Helicobacter pylori is a common human pathogen that has been identified to be carcinogenic. This study isolated the temperate bacteriophage 1961P from the lysate of a clinical strain of H. pylori isolated in Taiwan. The bacteriophage has an icosahedral head and a short tail, typical of the Podoviridae family. Its double-stranded DNA genome is 26,836 bp long and has 33 open reading frames. Only 9 of the predicted proteins have homologs of known functions, while the remaining 24 are only similar to unknown proteins encoded by Helicobacter prophages and remnants. Analysis of sequences proximal to the phage-host junctions suggests that 1961P may integrate into the host chromosome via a mechanism similar to that of bacteriophage lambda. In addition, 1961P is capable of generalized transduction. To the best of our knowledge, this is the first report of the isolation, characterization, genome analysis, integration, and transduction of a Helicobacter pylori phage.
