PMBT24, the first reported virulent bacteriophage infecting the anaerobic human gut bacterium Enterocloster bolteae strain MBT-21, was isolated from a municipal sewage sample and its genome was sequenced and analysed. Transmission electron microscopy revealed a phage with an icosahedral head and a long, non-contractile tail. The circularly permutated, 99,962-bp dsDNA genome of the pac-type phage has a mol% G + C content of 32.1 and comprises 173 putative ORFs. Using amino acid sequence-based phylogeny, phage PMBT24 showed similarity to other, hitherto non-published phage genomes in the databases. Our data suggested phage PMBT24 to present the type phage of a novel genus (proposed name Kielvirus) and novel family of phages (proposed name Kielviridae).
