Abstract

The in vitro phagocytosis of Loma salmonae spores by macrophages of Atlantic salmon and two strains of chinook salmon were investigated. Opsonisationof L. salmonae with plasma factors increased uptake by head kidney macrophages. Macrophages of Atlantic salmon, which are resistant to the parasite, had a significantly higher phagocytic index (PI) than those of chinook salmon, a susceptible species. This may indicate a possible mechanism contributing to resistance in Atlantic salmon or that L. salmonae is able to evade or suppress initial binding by macrophages of chinook. Non-specific binding or lectinophagocytosis was also suggested by significantly higher PI of spores from EDTA treated plasma when compared with no plasma or heat treated plasma. In comparison, uptake of Baker's yeast Saccharomyces cerevisiae by phagocytes was not significantly different between fish species and strains for all treatments. (C) 2001 Academic Press.
