Original Investigations


In the present study, the pathogenic effects ofSphaerospora dicentrarchi andS. testicularis, histozoic and coelozoic myxosporean parasites of the Mediterranean sea bassDicentrarchus labrax L., respectively, are described. The infection caused by the latter, which usually invades the testes and neighboring tissues, is considered to represent parasitic castration.S. dicentrarchi seems to be harmless except in massive infections, which probably result in organic disfunctions. The cellular host reaction generated byS. testicularis depends on the location of the parasite and is more intense than that produced byS. dicentrarchi. In both sphaerosporoses, macrophages, granulocytes, lymphocytes, plasmacytes, and fibroblast-like cells are involved. The role of the different immune cells is discussed.
