- Abstract
Viruses that infect bacteria are emerging as attractive biocontrol agents and biopreservatives for foods. Since these bacteriophages kill the target pathogens by lysis and are also consumed along with food, it is essential to evaluate their collateral toxicity on the probiotic gut microbiota. In this study, we examined the acute oral toxicity of a Salmonella phage isolated from sewage in mice. Acute oral administration of the Salmonella phage for five consecutive days did not show any significant pathological changes in the vital organs like lung, kidneys, heart, liver, and intestine. In addition, growth of typical probiotic microbiota remained unaffected even after incubation up to 24 h with the Salmonella phage. The results of this study clearly showed that oral administration of the lytic Salmonella phage did not have any significant adverse effects on the animals, may not harm the probiotic gut microbiota, and are likely to be safe for use in food preservation.
