A novel lytic siphophage, PLG-II, which is specific for Lactococcus garvieae serotype II strains that are pathogenic to fish, was isolated from seawater samples collected from Miyazaki Prefecture, Japan. Whole-genome sequencing showed that the PLG-II genome is a 32,271-bp double-stranded DNA molecule, with an average GC content of 37.74%. It contains 69 open reading frames (ORFs), 43 of which currently have no reliable functional annotation for their product, as well as a single tRNA. Comparative genomics analysis suggests that phage PLG-II might represent a novel species in the genus Uwajimavirus.
