Pseudomonas virus gh1 (Bacteriophage gh-1) is a bacteriophage capable of infecting susceptible strains of Pseudomonas putida.[1] It is a member of family Podoviridae, subfamily Autographivirinae.[2] It was first isolated in 1966 from a sample taken from the aeration tank at a sewage plant in East Lansing, Michigan.[citation needed]

Sedimentation analysis indicates that gh-1 carries its genetic payload in the form of a 37,359 bp linear strand of dsDNA,[3][4] inside an icosahedronal capsid 50 nm in diameter.[1]
One-step growth experiments indicate that the latent period is approximately 21 min, with a burst size of 103.[1]
It has been shown that this phage group requires an intact O-antigen on its host's outer membrane in order to successfully replicate and it is thus likely that lipopolysaccharide acts as the phage receptor.[3]
