Prevalence and intensity of Myxobolus cerebralis in host blood.

(A) Prevalence (in percentage) of the parasite in host species in the relation of sampling time. (B) Boxplot of parasite infection intensity in the examined host species. (C) Boxplot of infection intensity by host species and at different sampling points. Significant difference: A: p < 0.001. RBT: rainbow trout Onchorhynchus mykiss; BT: brown trout Salmo trutta m fario. Box-and-whisker plots: box: interquartile range; bold line in the box: median; whiskers: minimum and maximum values; point (circle): outlier. Log₁₀CNRQ: log10 transformed, calibrated normalized relative quantities of parasite DNA based on qPCR measurements.
