Prospect of Hydroxyl Radical Exposure during Seawater Bathing to Treat Amoebic Gill Disease in Atlantic Salmon

Figure 3

(a) Live NP cells in the cytometer tube are illustrated within the red polygon (P1) in terms of forward scatter height and side scatter height of light scattered from NP cells in seawater. The other polygons contain the presumably dead NP cells (P2) and contaminants in fresh seawater (P3). (b) Changes in viability of NP after 60 min .OH radical treatment in the cytometer tube. (c) A significant cluster of live NP cells through gating of P1 and P2 against the whole population of A before the start of treatment. (d) Separate clusters of live and dead NP cells after 60 min of .OH radical treatment through gating of P1 and P2 against the whole population of B.
