Field surveys for <i>Plum pox virus</i> (PPV) infection were conducted in stone fruit orchards all over Bulgaria. In total, 1168 out of 3020 leaf samples from cultivated <i>Prunus</i> spp. and wildly growing <i>P. cerasifera</i> trees reacted positive for PPV in DASI-ELISA with the universal monoclonal antibody (MAb) 5B. Further ELISA analyses showed that 987 and 127 isolates belonged to PPV-M and PPV-D serotypes, respectively. The plum and <i>P. cerasifera</i> showed 82.0% and 50.5% levels of i
