Historically, bacteriophages infecting their hosts have perhaps been best known and even notorious for being a nuisance in dairy-fermentation processes. However, with the rapid progress in molecular microbiology and microbial ecology, a new dawn has risen for phages. This review will provide an overview on possible uses and applications of Listeria phages, including phage-typing, reporter phage for bacterial diagnostics, and use of phage as biocontrol agents for food safety. The use of phage-encoded enzymes such as endolysins for the detection and as antimicrobial agent will also be addressed. Desirable properties of candidate phages for biocontrol will be discussed. While emphasizing the enormous future potential for applications, we will also consider some of the intrinsic limitations dictated by both phage and bacterial ecology.

Background: Vibrio parahaemolyticus is a marine bacterium causing seafood-associated gastrointestinal illness in humans and acute hepatopancreatic necrosis disease (AHPND) in shrimp. Bacteriophages have emerged as promising biocontrol agents against V. parahaemolyticus.

Avian pathogenic Escherichia coli (APEC) is the main causative agent of colibacillosis, causing poultry respiratory infections, mortality and economic loss. APEC poses a serious threat to public health and food safety due to its multi-drug resistance and capacity to form biofilms. Bacteriophages (phages) have emerged as an alternative to antibiotics.

Caspase family proteases and Toll/interleukin-1 receptor (TIR)-domain proteins have central roles in innate immunity and regulated cell death in humans. We describe a bacterial immune system comprising both a caspase-like protease and a TIR-domain protein. We found that the TIR protein, once it recognizes phage invasion, produces the previously unknown immune signaling molecule adenosine 5'-diphosphate-cyclo[N7:1'']-ribose (N7-cADPR).

Because of the global spread of multi- and pan-resistant bacteria, there is a need to identify, research, and develop new strategies to combat these pathogens. In a previous proof-of-concept study, we presented an innovative strategy by genetically modifying lytic T7 bacteriophages. We integrated DNA fragments encoding for derivatives of the antimicrobial peptide (AMP) apidaecin into the phage genome to induce the production and release of apidaecin within the T7 infection cycle, thereby also targeting phage-resistant bacteria.

Caspase recruitment domains (CARDs) and pyrin domains are important facilitators of inflammasome activity and pyroptosis. Following pathogen recognition by nucleotide binding-domain, leucine-rich, repeat-containing (NLR) proteins, CARDs recruit and activate caspases, which, in turn, activate gasdermin pore-forming proteins to induce pyroptotic cell death. Here we show that CARD domains are present in defence systems that protect bacteria against phage.
