We report the selection and amplification of the broad-host-range Salmonella phage phi PVP-SE1 in an alternative nonpathogenic host. The lytic spectrum and the phage DNA restriction profile were not modified upon replication in Escherichia coli Bl21, suggesting the possibility of producing this phage in a nonpathogenic host, contributing to the safety and easier approval of a product based on this Salmonella biocontrol agent.

serovar Rissen ( Rissen) is an emerging causative agent of foodborne diseases. The current emergence of antibiotic resistance makes necessary alternative therapeutic strategies. In this study, we investigated the potential of a phage-resistant strain of Rissen (R) as a tool for developing an effective lipopolysaccharide (LPS)-based vaccine.

Advances in bacteriophage genome sequencing and regulatory approvals of some bacteriophages in various applications have renewed interest in these antibacterial viruses as a potential solution to persistent food safety challenges. Here, we analyzed in depth the genome of the previously studied bacteriophage OSYSP (phage OSYSP), revealed its application-related characteristics, and optimized its enumeration techniques for facilitating industrial implementation. We previously sequenced phage OSYSP genome completely by combining results from Illumina Miseq and Ion Torrent sequencing platforms and completing the remaining sequence gaps using PCR.

Background: Bacteriophages (or phages) replicate by utilizing bacterial resources and destroy their host cells at the end of the replication cycle. Phages employ multiple proteins to optimize host cell lysis, thereby maximizing the production of phage particles. However, elucidating the entire lysis process is challenging due to the abundance of uncharacterized genes in the phage genome.
