Pierce’s disease is a lethal grapevine disease caused by the bacterium Xylella fastidiosa which infects the xylem tissue of grapevine. Bacterial aggregates and plant tyloses and gums, produced in response to infection, are thought to block the vessels which conduct water through the plant. Xylella fastidiosa is a gram-negative bacterium confined to the xylem vessels of its host. The organism, designated Xylella fastidiosa was first described by Wells et al. (1987), and is the sole species belonging to this genus. X. fastidiosa has not been recorded in Australia.
