In this study, the possibility of the vertical transmission of Circovirus was investigated in a flock of infected Gouldian finches. The detected virus was previously classified as a BFDV strain by sequence analysis. Eggs were collected in the flock for three subsequent reproductive seasons. The DNA virus was found in the eggs only in the first reproductive season. 24,39 % of the tested eggs resulted positive. Circovirus DNA was detected in yolk while all samples of glair tested negative. The findings strongly suggest that the vertical transmission of circovirus is possible. Nevertheless, it seems to occur only in the first year of the outbreak.
