 en A note on stability in food matrices of Salmonella enterica check for this species in other resources serovar Enteritidis-controlling bacteriophages
Robeson, James; Turra, Gabriel; Huber, Karen & Borie, Consuelo


Background: Lytic bacteriophages are bacterial viruses that upon infection kill their host cells and therefore have re-emerged as biological control agents of bacterial pathogens, particularly in the field of food related infections. Here, we investigated the stability in different food matrices of five phage isolates capable of controlling the foodborne pathogen Salmonella enterica check for this species in other resources serovar Enteritidis (SE).
Results: We found that twophages, originally isolated fromfood sources,were up to 5 logsmore stable than three phages isolated from sewage, in ten food matrices (fresh and processed) at both 4°C and 18°C.
Conclusion: Lytic phages isolated from contaminated food sources seem to be a better choice when structuring phage cocktails to be used in the control of SE in food management protocols.
