Identification and characterization of ϕH111-1: A novel myovirus with broad activity against clinical isolates of Burkholderia cenocepacia.

ABSTRACT: Characterization of prophages in sequenced bacterial genomes is important for virulence assessment, evolutionary analysis, and phage application development. The objective of this study was to identify complete, inducible prophages in the cystic fibrosis (CF) clinical isolate Burkholderia cenocepacia H111. Using the prophage-finding program PHAge Search Tool (PHAST), we identified three putative intact prophages in the H111 sequence. Virions were readily isolated from H111 culture supernatants following extended incubation. Using shotgun cloning and sequencing, one of these virions (designated ϕH111-1 [vB_BceM_ϕH111-1]) was identified as the infective particle of a PHAST-detected intact prophage. ϕH111-1 has an extremely broad host range with respect to B. cenocepacia strains
