Figs. 4–5 Myxobolus macrocapsularis. 4. Large plasmodium (p) at the tip of the gill filament of a common bream. 5. Plasmodium (p) close to the tip of the gill filament of a white bream. The plasmodium developed in the filament artery. Some free spores released
from the plasmodium fill the lumen of the artery (large arrow). In this region of the filaments gill lamellae are still seen (small arrows). Histological sections (H. & E.). Scale-bars: 4, 200 lm; 5, 100 lm
