Abstract The effects of trickle infections of water buffaloes with Fasciola hepatica (60 metacercariae daily during a period of 20 days) on the blood plasma levels of prostaglandin E(2) (PGE2), 6-keto-prostaglandin F(1alpha) (6-keto-PG F(1alpha)) and thromboxane B(2) (TXB2) were assessed. F. hepatica specific IgG and T- and B-lymphocyte ratios were evaluated as indicators of the immune response. Although the applied mode of infection did not result in clinical disease, changes in the plasma eicosanoid pattern were observed. Plasma PGE2 values were significantly elevated in the infected water buffaloes 11 weeks post-infection (w.p.i.). In contrast, transiently but significantly lower TXB2 values than in the uninfected controls were recorded in the phase of chronic fasciolosis. Plasma 6-keto-PGF(1alpha) values were not considerably altered by the infection throughout the study period. F. hepatica-specific IgG were detected from 4 to 21 w.p.i. The proportion of peripheral T- and B-lymphocytes shifted towards B-cells from 2 to 12 w.p.i., gradually returning to control values afterwards. Although the water buffaloes appeared to be rather resistant to trickle infection with F. hepatica, moderate changes in plasma eicosanoid patterns were observed, indicating tissue damage and/or inflammation. Induction of the immune response could be monitored by an increase of F. hepatica-specific IgG, which was paralleled by a relative increase of the B-lymphocyte population.
