Identification of the fire blight pathogen, Erwinia amylovora, by PCR assays with chromosomal DNA

S Bereswill; P Bugert; I Bruchm�ller; et al. Applied and Environmental Microbiology 1995. doi:10.1128/aem.61.7.2636-2642.1995

Other claims from this paper (5)

Method / resource Chromosomal DNA PCR assays identified Erwinia amylovora independently of pEA29.
Observation The amplified 1.6 kb fragment had an identical sequence in two E. amylovora strains.
Method / resource The PCR signal detected the fire blight pathogen amid other plant-associated bacteria and in infected plant tissue.
Method / resource HaeIII digestion of amplified 16S rRNA products distinguished E. amylovora from other bacteria.
Method / resource Arbitrarily primed PCR yielded a unique banding pattern for all investigated E. amylovora strains.
