Salmonella is a common and widely distributed foodborne pathogen that is frequently implicated in gastrointestinal infections. The emergence and spread of Salmonella strains resistant to multiple antibiotics poses a significant health threat, highlighting the urgent need for early and effective therapeutic strategies. We isolated a total of 32 phages from water samples and anal swabs from pigs. Of these, three phages that produced large, clear plaques were selected for thither study using the following methods: electron microscopy, analysis of the life cycle parameters, genetic analysis, inhibition of bacterial growth, and activity against biofilms. The three Salmonella phages (vB_SenS_CSP01, vB_SenS_PHB06, and vB_SenS_PHB07) were assigned to the family Siphoviridae on the basis of their morphology. All showed polyvalent infectivity, and individual phages or phage cocktails could inhibit the growth of host Salmonella enterica serovar Enteritidis strains or reduce biofilm formation by Salmonella enterica serovar Typhimurium. In summary, these three phages merit further research as biocontrol agents for Salmonella infection.
