Table 4.
Parasite, host, clinical signs, visibility categories (vis. cat.), location, type of plasmodium and lesions caused by myxozoan parasites in the gills of aquaculture fingerlings from Punjab. Visibility category A: not visible under stereozoom B: visible under stereozoom C: visible with the naked eye. D: Very large type of plasmodia visible with the naked eye. Plasmodium type (per tissue location): LV1: intralamellar vascular plasmodium located centrally in the gill lamella; LV3: Large plasmodium by the fusion of several gill lamellae; FV2: large plasmodia formed by the fusion of several plasmodia near the end of the gill filament (Vis. Cat. See Materials and Methods)
