Table 1 The recovery of Salmonella Enteritidis and Salmonella Typhimurium from the skin of experimentally-infected chickens which have been treated with a buffer (control) or phage suspension. The number of skin sections from which Salmonella could be recovered by MPN enrichment is given out of a total of 18. The median log10 MPN recovery per skin section is also given, along with the range. Skin sections which contained the same or more than the maximum detection limit for the MPN technique were assigned the value “≥ 3.04”

Bacterial contaminant Control (buffer-treated) group Phage-treated group
No. of Salmonella positive skin sections (%) Median MPN per skin section (range) No. of Salmonella positive skin sections (%) Median MPN per skin section (range)
S. Enteritidis 18/18 (100.0) 1.38 (0.95 to ≥3.04) 5/18 (27.8) 0.00 (0.00 to 1.11)
S. Typhimurium 18/18 (100.0) 2.43 (1.46 to ≥3.04) 11/18 (61.1) 0.60 (0.00 to 2.66)
