Sixteen field strains of goose parvovirus (GPV) and DNA extracted from standard strain of Muscovy duck parvovirus (MDPV) were used. PCR was used for the amplification of the VP3 structural protein encoding region. In the case of all GPV strains and one MDPV strain the presence of specific product about 1,604 bp long was observed. The essential conditions, which had the influence on the specificity, sensitivity, and efficiency of the amplification reaction, were optimised. In order to eliminate unspecific interactions between template and primers touchdown PCR was applied. Additionally, for specificity and efficiency improvement, betaine (N, N, N - trimethylglycine) was added. The conducted optimisation steps of PCR allowed for the identification of the both parvoviruses.
