Strains lysogenic for either of these phages are immune to lysis by the same phage but are sensitive to the other phage. PBL1 has an oval head, a non-contractile tail, and a base plate with a pin structure but no apparent tail fibres. The genome of PBL1 consists of double-stranded DNA with a molecular weight of 24.1 (±0.6) × 106, a G + C content (derived from melting temperature) of 41.5%, and cohesive ends. Restriction enzyme analysis permitted construction of a physical map of the genome. %U https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-65-6-1101
