Figure 2From: Potassium permanganate elicits a shift of the external fish microbiome and increases host susceptibility to columnaris disease Mean cumulative percent mortality of channel catfish challenged with Flavobacterium columnare. (I) control = not treated nor challenged, (II) PP = treated with PP and not challenged, (III) F = not treated with PP and challenged with F. columnare, and (IV) PP + F = treated with PP and challenged with F. columnare. (Note: treatments I and II had 0% mortality, so the mortality curves are superimposed).Back to article page
