Figure 6.

Average reduction of Staphylococcus aureus contamination in situ, by a combined phage–probiotic detergent. Surfaces were artificially contaminated with S. aureus and subsequently treated as described in Figure 5. Results are expressed as mean value ± SD of duplicate samples from three independent experiments. CTR, water; PCHS, probiotic detergent alone; phages, anti-staphylococcal phages in PBS alone; PCHS + phages, probiotic detergent including anti-staphylococcal phages.

Abbreviations: PCHS, Probiotic Cleaning Hygiene System; PBS, phosphate-buffered saline; CTR, control; h.p.t, hours post treatment; d.p.t, days post treatment.
