Sažetak
Fascioloides magna is an alien parasite species in Croatia. Despite the fact that the red deer is termed as definitive final host, we can classify this relationship as a recently established and still developing host-parasite association. On the opposite, wild boar is classified as a dead-end host. Following the infection, juvenile flukes migrate through the liver causing the extensive tissue damage, while in the same time liver responds initiating various defence mechanisms. We have collected 29 samples of red deer livers from four counties (Vukovarsko-srijemska, Požeško-slavonska, Sisačko-moslavačka, and Bjelovarskobilogorska) from which 58 pseudocysts were isolated and 4 wild boar livers originating from Sisačko-moslavačka County, with 4 isolated lesions suggestive to be caused by flukes. Tissue samples were collected from selected areas that cover most of the wall of pseudocysts and surrounding tissues and fixed in the 10% buffered formalin. Samples were processed routinely and stained using H&E. In comparison, non-infected wild boar livers have more pronounced connective tissue than those of red deer. Inflammatory infiltrate in red deer livers contains predominantly lymphocytes, followed by neutrophils and eosinophils. In wild boar it is formed of mainly eosinophils, followed by neutrophils and lymphocytes. Thickening of blood vessels media and dilatation of sinusoids was observed in areas surrounding pseudocysts. The most common finding in the pseudocyst included necrotic debris, fluke’s eggs, and pigmented granules.
