FIG. 3.

Effect of an injection of 0.2 or 1 μM ACTH/g or FSW on circulating NA concentrations (a), cumulative mortality (b and c), and V. splendidus loads (d and e) in juvenile oysters challenged (Chal) with a low dose of V. splendidus (100 bacteria/oyster) or injected with sterile culture medium (Med). Data in panels a to c are means and standard errors from three replicate experiments. For panels d and e, bacterial counts were performed five times on solid-TCBS cultures obtained from a single experiment.
