Abstract

Investigation was carried out to assess and compare the seasonal changes of some haematological parameters in naturally
infected and uninfected roach (Rutilus rutilus) with Cryptobia tincae. Prevalence of Cryptobia tincae was 17.8 % in winter, 25 %
in spring, 17.9 % in summer and 16.3 % in autumn. On average, between 0.1 and 0.2 parasites per microscopic field were noted at
100× magnification. No statistically significant differences were observed for erythrocyte, leucocyte, haematocrit values between
parasitized and unparasitised roach for each season (p> 0.05), except for haematocrit in autumn (p< 0.05). Seasonally, the
significant differences were found for erythrocyte and haematocrit both infected and uninfected roach while it was not found
for leucocyte. In the leucocyte profiles, the significant differences were estimated for neutrophiles in spring, for eosinophiles in
autumn between infected and uninfected roach (p < 0.05).
