Figure 3.

Immunological and lipid metabolism-related parameters measured in mussels Mytilus galloprovincialis exposed to Azadinium dexteroporum (black bars) and control mussels (white bars). (a) Phagocytosis activity; (b) lysosomal membrane stability, measured as neutral red retention time (NRRT); (c) granulocyte/hyalinocyte ratio; (d) neutral lipid content; (e) activity of acyl-CoA oxidase; (f) lipofuscin content. Values are expressed as mean ± st. dev. (n = 5). Asterisks represent statistically significant differences between means, in exposed and control groups (p < 0.05).
