Rediae of echinostomatid and heterophyid trematodes suppress phagocytosis of haemocytes in Littorina littorea (Gastropoda: Prosobranchia)

| description | A modulation of the phagocytic activity of hemocytes from the common periwinkle
Littorina littorea by secretory–excretory products (SEP) released by trematode rediae during axenic in vitro cultivation was studied. The SEP released by the parasites
Himasthla elongata (Echinostomatidae) and
Cryptocotyle lingua (Heterophyidae) were found to inhibit the phagocytosis of zymozan particles by periwinkle hemocytes. The specificity of SEP effects was assessed: SEP of
Himasthla militaris and
Cryptocotyle concavum, two trematodes belonging to the same genera but infecting another closely related prosobranch snail
Hydrobia ulvae, were also shown to be able to suppress
L. littorea hemocytes phagocytic activity. However, no decrease in phagocytosis rate was observed when SEP of
H. elongata and
C. lingua were applied to monolayers of hemocytes from the bivalve mollusc
Mytilus edulis. SEP from
H. elongata was fractionated; only those fractions containing proteins of molecular weight more than 50
kDa were shown to possess inhibitory activity. Different
H. elongata SEP concentrations were tested in for their ability to suppress phagocytosis by
L. littorea hemocytes. Even very low SEP concentrations were shown to retain their ability to decrease phagocytosis rate, the inhibitory effect being dose-dependent. Hemocytes derived from snails naturally infected with
H. elongata were also found to have lower phagocytic ability as compared to healthy individuals. |
