A novel bacteriophage, vB_KpnP_KpV289, lytic for hypermucoviscous strains of Klebsiella pneumoniae, was attributed to the family Podoviridae, subfamily Autographivirinae, genus T7likevirus based on transmission electron microscopy and genome analysis. The complete genome of the bacteriophage vB_KpnP_KpV289 consists of a linear double-stranded DNA of 41,054 bp including 179-bp direct-repeat sequences at the ends and 51 open reading frames (ORFs). The G+C content is 52.56 %. The phage was shown to lyse 15 out of 140 (10.7 %) K. pneumoniae strains belonged to the capsular types K-1, K-2, and K-57 and strains without a determined capsular type, including a hypermucoviscous strain of the novel sequence type ST-1554.
