Application of a Broad Range Lytic Phage LPST94 for Biological Control of Salmonella in Foods.

ABSTRACT: Salmonella, one of the most common food-borne pathogens, is a significant public health and economic burden worldwide. Lytic phages are viable alternatives to conventional technologies for pathogen biocontrol in food products. In this study, 40 Salmonella phages were isolated from environmentally sourced water samples. We characterized the lytic range against Salmonella and among all isolates, phage LPST94 showed the broadest lytic spectrum and the highest lytic activity. Electron microscopy and genome sequencing indicated that LPST94 belongs to the Ackermannviridae family. Further studies showed this phage is robust, tolerating a wide range of pH (4-12) and temperature (30-60 °C) over 60 min. The efficacy of phage LPST94 as a biological control agent was evalua
