The effect of phosphorylcholine (PC) on serum mediated adherence of fish leucocytes to the plerocercoid of Ligula intestinalis has been investigated. Parasites removed from the body cavity of naturally infected roach (Rutdus rutilus) fry were cultured for 24 h in Leibovitz' medium and then exposed in vitro to leucocytes obtained from the pronephros of healthy roach and either untreated or PC-treated normal roach serum or immune roach serum. Ultrastructural observations revealed that the addition of PC to serum reduced leucocyte adherence; however, this was only significant in assays containing treated normal roach serum. In all assays macrophages, neutrophils and lymphocytes were present on the parasite surface, and phagocytosis of the microtriches by the former 2 cell types occurred.
