Short communication Characterization of Erwinia amylovora strains from Croatia
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 differences in restriction fragment length polymorphism of the XbaI genomic DNA digest analysed with pulsed-field gel electrophoresis. This technique was also used to determine the genetic relatedness of six Croatian isolat...
متن کاملBacteriophages 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 کاملIsolation and characterization of five Erwinia amylovora bacteriophages and assessment of phage resistance in strains of Erwinia amylovora.
Phages able to infect the fire blight pathogen Erwinia amylovora were isolated from apple, pear, and raspberry tissues and from soil samples collected at sites displaying fire blight symptoms. Among a collection of 50 phage isolates, 5 distinct phages, including relatives of the previously described phages phiEa1 and phiEa7 and 3 novel phages named phiEa100, phiEa125, and phiEa116C, were identi...
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 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 ...
