Bacteriophages of Erwinia amylovora.
Fifty bacteriophage isolates of Erwinia amylovora, the causal agent of fire blight, were collected from sites in and around the Niagara region of southern Ontario and the Royal Botanical Gardens, Hamilton, Ontario. Forty-two phages survived the isolation, purification, and storage processes. The majority of the phages in the collection were isolated from the soil surrounding trees exhibiting fi...
متن کاملPhenotypic diversity of Erwinia amylovora in Bulgaria.
Fifty-one strains of Erwinia amylovora isolated from nine host plants in Bulgaria were characterized phenotypically and identified by the API 20E and BIOLOG system. The identification was confirmed by PCR amplification of a specific region of the plasmid pEA29 and the genome ams region. The phenotypic diversity of the strains was studied on the basis of their API 20E and BIOLOG metabolic profil...
متن کاملMolecular characterization of global regulatory RNA species that control pathogenicity factors in Erwinia amylovora and Erwinia herbicola pv. gypsophilae.
rsmB(Ecc) specifies a nontranslatable RNA regulator that controls exoprotein production and pathogenicity in soft rot-causing Erwinia carotovora subsp. carotovora. This effect of rsmB(Ecc) RNA is mediated mostly by neutralizing the function of RsmA(Ecc), an RNA-binding protein of E. carotovora subsp. carotovora, which acts as a global negative regulator. To determine the occurrence of functiona...
متن کاملIntermediary metabolism of carbohydrate by Erwinia amylovora.
Erwinia amylovora ferments glucose to yield mainly ethanol, lactate, and carbon dioxide (Sutton and Starr, 1959). The initial steps in the o.xidation of glucose by this bacterium were reported by Katznelson (1955), who later (Katznelson, 1958) showed the presence of certain key enzymes of the Embden-Meyerhof pathway in sonic extracts. The present study, briefly summarized elsewhere (Sutton and ...
متن کاملVirulence Factors of Erwinia amylovora: A Review
Erwinia amylovora, a Gram negative bacteria of the Enterobacteriaceae family, is the causal agent of fire blight, a devastating plant disease affecting a wide range of host species within Rosaceae and a major global threat to commercial apple and pear production. Among the limited number of control options currently available, prophylactic application of antibiotics during the bloom period appe...
