Sequential Development and Morphology of Experimentally Induced Hepatic Melano-Macrophage Centres in 'Rivulus marmoratus'

摘要

Formation of hepatic melano-macrophage centers (MMC's) in Rivulus marmoratus was induced with the coccidian parasite Calyptospora funduli. Experimental infections were produced by feeding infected intestine and hepatopancreas from grass shrimp (Palaemonetes pugio) to individual parasite-free fish. The results suggests that MMC formation in this case is an inflammatory process in which mononuclear cells recruited from peripheral circulation play a dominant role. MMC development appears to be elicited by macrogamont degeneration, whereas granuloma formation probably is a response to oocysts. (Copyright (c) 1987 The Fisheries Society of the British Isles.)
