Histological Study on the Myxosporean Infection in the Gills of Common Carp, Cyprinus carpio (Linnaeus,1785)
- In the histological study, mature spores of Myxobolus sp. 2 were found at the tip of the gill filament of Cyprinus carpio. Two types of plasmodia were found and were rounded in shape. Small plasmodia (mean: L = 36.8 x W = 36.5 µm) were observed between gill lamellae. Large plasmodia (mean: L = 150.4 x W = 106.0 µm) were also found in the distal, middle and basal region of the gill filament. Plasmodia were found along the length of the gill filament. Some plasmodia were also found in the gill lamellae. Dilation of blood vessels in the gill filament and infiltrated cells were found as histopathological changes. With the evidence of histological changes, myxosporean parasites may cause a disturbance in the respiratory process of the infected common carp.
