摘要: Three salmonid fish species, Oncorhynchus mykiss, Salmo salar and trutta, were infected experimentally with the parasitic nematode Anisakis simplex (A. simplex) difference between in vivo behaviour of three species was investigated. Infection success rate differed species. S. (Baltic salmon) showed highest number successfully established nematodes, whereas trutta (brown trout) O. mykiss (rainbow had a higher natural resistance. Microhabitat selection nematodes according to In brown trout, A. larvae attached digestive tract (stomach, pyloric caeca, intestine), while majority found rainbow trout located caeca. Baltic salmon, dispersed on spleen, head kidney, liver, swim bladder musculature. Encapsulation inflammatory cellular reactions accordingly. Histopathological immunohistochemical studies using monoclonal antibodies raised against IgM, CD8 MHCII performed detect presence immune cells around infecting nematodes. None positive for IgM-bearing tissue connected CD8+ detected all MHCII-bearing associated encapsulated but not salmon. Physiological, immunological pathological implications microhabitat differences are discussed.
