Fig. 2

a A polysporous plasmodium of Paramyxidium giardi inside a kidney tubule of Anguilla anguilla, where is causes extensive widening of the tubules causing atrophy and necrosis of the tubular epithelial cell (arrow); insert shows higher magnification of spores from within the yellow box. b A polysporous plasmodium of P. magi n. sp. in the gastric gland of stomach wall; insert shows higher magnification of spores from within the yellow box. c Normal secondary gill lamellae of A. anguilla (white arrow) and one infected with P. branchialis n. sp. (yellow arrow). The large plasmodium causes disruption of epithelium and the pillar cells of the secondary lamella; insert shows higher magnification of spores from within the yellow box. d P. bulani n. sp. infection in the kidney of a Pacific tarpon. The parasite develops inside the kidney tubules, often attached to the brush border of the tubular epithelial cells, without causing any apparent pathology. Abbreviations: GG, gastric glands; NT, normal tubule
