a Resistance to the following antibiotics was tested using minimal inhibitory concentration (MIC) and disc diffusion tests: tetracycline, rifampicin, ampicillin, chloramphenicol, colistin, enrofloxacin, and kanamycin. The resistance/susceptibility was determined on the basis of EUCAST guidelines. Investigated strains were susceptible to all tested antibiotics, with the exception of colistin for strains indicated by asterisks. b Abbreviations: NSC, National Salmonella Centre, Poland; DMB UG, Department of Molecular Biology of University of Gdansk, Poland. c Phage titer on S. Heidelberg UGSA2 was used as a reference value (100%). Mean values from three independent experiments are shown with SD.
