General Information: This bacterium is the causative agent of Fire Blight, a destructive disease of Maloid fruit trees, such as apple and pear. Outbreaks are sporadic in the Northeast, but result in serious damage to roots, blossoms, fruit, and shoots when they occur. The pathogen overwinters in cankers or in smaller limbs. During early spring, in response to both temperature increases and bud development, the bacteria multiplies and may be seen as a yellowish ooze around the perimeter of the canker. Flies and other insects are attracted to the ooze and disperse the inoculum to other trees in the orchard. This species has recently become resistant to streptomycin, an antibiotic traditionally used in its control.
