Two different strains (IVIA 5901 and ESVL), isolated from almond trees in two municipalities of the Demarcated Area, were used to carry out pathogenicity tests on different plant species. The Italian strain De Donno (subsp. pauca, ST53) and the Spanish strain IVIA 5770 (subsp. fastidiosa, ST1) were also included.
