Reduction in the number of bacteria (S. enterica serotypes Typhimurium (A,B) and Enteritidis (C,D)) from biofilm by phages vB_SenM-1 (white bars), vB_SenM-2 (grey bars), and vB_SenS-3 (navy blue bars) at 25, 37, and 42 °C. CFU/mL of bacterial biofilm untreated with bacteriophages was used as control and reference value (100%). Mean values from three independent experiments are shown, with error bars representing SD. Statistical analysis was performed using t-test; p < 0.05 (*), p < 0.01 (**).
