Figure 2

Live-Dead-stained Campylobacter cells exposed to silver ion-treated crate material and standard crate material. Cells stained during logarithmic phase growth in Bolton broth (a) fluoresce green indicating viability. Cells photographed 1 h (b), 2 h (c) and 4 h (d) after exposure to silver ion containing crate material show an increasing red/orange fluorescence indicating a progressive reduction in viability. Live-Dead-stained Campylobacter cells exposed to untreated crate material show less reduction in viability over a 4-h period (e) compared to d.
