The results of ddPCR pigeon circovirus quantification during the whole experimental period in blood (a) and cloacal swab (b) samples acquired from the experimental pigeons. The different letters (a,b) indicate a statistically significant difference in PiCV genome copy numbers between the sampling dates (p < 0.05). Whiskers represent the standard deviation values. The results for the individual pigeons are encoded by color according to Fig. 1.
