Bam35, a 15-kbp double-stranded DNA phage, infects Bacillus thuringiensis. Recently, sequencing of the related Bacillus cereus revealed a 15.1-kbp linear plasmid, pBClin15. We show that pBClin15 closely resembles Bam35 and demonstrate conversion of Bam35 to a prophage. This state is common, as several B. thuringiensis strains release Bam35-related viruses.
