Fire blight, a bacteriosis of apple and pear, was assayed with molecular tools to associate its
origin in Russia, Slovenia and south-eastern Austria with neighboring countries. The …

Fire blight has been detected recently in several areas of northern Spain and north‐eastern
Italy. To follow spread of the disease within Europe, more than 120 Erwinia amylovora …

A collection of 127 strains of Erwinia amylovora, the causative agent of fire blight, was tested
by PCR amplification of a fragment of the plasmid pEA29. A variability in the length of the …

Virulent Erwinia amylovora strains, isolated at different times in different areas of Italy and
Spain, were assayed by PFGE analysis of genomic DNA after an Xba I digestion. Strains …

Erwinia amylovora is the causative agent of fire blight, a destructive disease of rosaceous
plants. The European population can be divided into several subtypes according to …

Erwinia amylovora is a phytopathogenic bacterium that causes fire blight, an economically
important disease of Rosaceae. Several isolates from pears and apples with fire blight …

Erwinia amylovora, the causal agent of fire blight, carries the common plasmid pEA29 of 29
kb. To screen for occurrence of natural strains without plasmid pEA29, we applied PCR …

Fire Blight, an economically relevant disease of apple, pear, and quince trees that is caused
by the Gram-negative bacterium Erwinia amylovora, was first reported from Kyrgyzstan in …

Eleven Erwinia amylovora isolates, the causal agent of the fire blight disease, were isolated
from apple orchards adjacent to those of pears showing fire blight disease symptoms. Initial …

Aims: The three main aims of the study were the assessment of the genetic relationship
between a deviating Erwinia amylovora strain isolated from Amelanchier sp.(Maloideae) …
