UNASSIGNED: Strains of the @entity6329 @entity6329 group have been extensively studied because some are used as probiotics in foods. Conversely, their phages have received much less attention. Here we analyze the complete genome sequence of five @entity6983 temperate phages, CL1, CL2, iLp84, iLp1308 and iA2. Only phage iA2 could not replicate in an indicator strain. Genome length varied from 34,155 bp (iA2) to 39,474 bp (CL1). Phages iA2 and iLp1308 (34,176 bp) possess the smallest genomes reported, so far, for phages of the @entity6329 group. The GC content of the five ranged from 44.8% to 45.6%. As observed with many other phages, their genome was organized as follows: genes coding for DNA packaging - morphogenesis - lysis - lysogeny - replication. Phages CL1, CL2 and iLp1308 are highly related to each other. Phage iLp84 was also related to these three phages but the similarities were limited to gene products involved in DNA packaging and structural proteins. Genomic fragments of phages CL1, CL2, iLp1308 and iLp84 were found in several genomes of @entity6329 strains. Prophage iA2 is unrelated to these four phages but almost all of its genome was found in at least four @entity6329 strains. Overall, these phages are distinct from previously characterized @entity6329 phages. Our results highlight the diversity of @entity6329 phages and indicate frequent DNA exchanges between phages and their hosts.
