Inhibition of adsorption and infection of EP75 to E. coli O157 and Salmonella O9 strains by TSP2 and TSP3. EP75 phage particles added to E. coli (A) or Salmonella (B) pre-treated with TSP2 or TSP3, respectively, had significant reduction in their cell binding ability. No effect was observed when treated with TSP1, TSP4 or GFP. The efficiency of plating (EOP) of EP75 against E. coli (C) or Salmonella (D) strains was also significantly reduced in the presence of TSP2 or TSP3. Data presented as mean ± SD. Two-way ANOVA showed significant difference for TSP2 or TSP3 treatments only (****, P < 0.0001), with no significance observed among the other treatments.
