Bacteriophage gh-1 is a bacteriophage capable of infecting susceptible strains of Pseudomonas putida.[1] It is a member of the genus Ghunavirus, family Autotranscriptaviridae, order Autographivirales.[2] It was first isolated in 1966 from a sample taken from the aeration tank at a sewage plant in East Lansing, Michigan.[1]
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]
