The phenoloxidase (PO) activity of the haemolymph and haemocytes from three clam species of commercial interest (Ruditapes philippinarum, Chamelea gallina and Tapes decussatus) has been compared. The activity was assayed spectrophotometrically by recording the formation of dopachrome from L-DOPA using sodium dodecyl sulphate, laminarin, trypsin or lipopolysaccharide as elicitors. Fewer PO units were observed in the haemolymph from T. decussatus than in the haemolymph from R. philippinarum, while the highest values were found in C. gallina. In all cases the activity was only significantly increased when sodium dodecyl sulphate was used as elicitor. PO activity in the haemocytes of all three clam species showed a very similar pattern to that found in the haemolymph from the same species. Furthermore, T. decussatus naturally parasitized by Perkinsus atlanticus (Protozoa, Apicomplexa) was used to study the influence of such infestation on PO activity, which was found to increase significantly in both haemolymph and haemocytes compared with non-infected (control) samples. PO activity in the haemocytes and in the haemolymph was higher when the level of parasitization was low or medium, respectively, and SDS was used as elicitor. No statistically significant differences were observed when the parasitization level was high. The present work constitutes the first report on the influence of this parasite on PO activity in haemolymph and haemocytes from T. decussatus.
