During the years 2006 and 2007, serious outbreaks of bacterial leaf and flower spot disease were observed on zinnia (Zinnia elegans Jaqc. cv. Mondo and Capricio) plants grown in several parks in Budapest, Hungary. Five strains of Xanthomonas campestris pv. zinniae isolated from diseased zinnia plants were identified based on morphological, physiological, biochemical and pathogenicity tests, as well as sequence analysis of the bacterial 16S-23S rDNA spacer region.
