Erwinia amylovora: historia de una superbacteria
Revista Digital Universitaria, 2023Históricamente, el tizón de fuego (causado por la bacteria Erwinia amylovora) ha sido un referente en el estudio de enfermedades de plantas. La comprensión y el estudio de esta enfermedad han beneficiado a la fitopatología, además, ha propiciado avances importantes en otras ciencias como la biotecnología y la microbiología.

HETEROLOGOUS EXPRESSION OF EPS-GENES IN ERWINIA AMYLOVORA AND ERWINIA STEWARTII
Acta Horticulturae, 1993A gene cluster for exopolysaccharide (EPS) synthesis of Erwinia amylovora was cloned in cosmid pEA109 and identified by complementation of Erwinia stewartii mutants deficient in EPS−production (cps). A corresponding cluster from E. stewartii (pES2144) complemented EPS−mutants of E. amylovora (ams). Two EPS−dependent phages were used to characterize EPS

YEASTS AS ANTAGONISTS AGAINST ERWINIA AMYLOVORA
Acta Horticulturae, 2006Epiphytic yeasts are potential antagonists to fire blight in apple blossoms. They showed effects against Erwinia amylovora in field experiments and reduced symptoms on detached apple blossoms. In this study, strains of Aureobasidium pullulans and Metschnikowia pulcherrima were investigated using the immature pear fruit assay and agar diffusion assay ...

Capsulation and virulence in Erwinia amylovora
Annals of Applied Biology, 1978SUMMARYEvidence is presented that capsulation may be one virulence determinant for Erwinia amylovora, the fireblight pathogen.When 15 virulent and seven avirulent strains were grown on a medium containing asparagine as the only source of carbon and nitrogen, or yeast peptone agar, or on a sugar medium containing an inorganic source of nitrogen, capsule

Serological Differences among Erwinia amylovora Biovars
Journal of General Plant Pathology, 2002Serological properties were compared among four biovars of Erwinia amylovora. Two biovars (bvs. 1 and 2) from Maloideae sources outside of Japan, one (bv. 3) from Rubus idaeus and one causing bacterial shoot blight of pear (bv. 4) had different reactions in Ouchterlony double diffusion tests using living cells and lipopolysaccharides (LPS) as antigens.

Biological control of Erwinia amylovora by Erwinia herbicola
1993A naturally-occurring Erwinia herbicola strain, Eh1087, inhibitory to Erwinia amylovora (Burr.) Winslow et al. (1920) was isolated from apple blossom (Malus X. domestica Borkh.) in a Canterbury orchard. Total populations of E. herbicola on apple blossoms in Canterbury and Hawkes Bay orchards were low (less than 50 cfu.blossom-1) throughout flowering ...

Fireblight (Erwinia amylovora)current danger
Bilten Poljodobra, 1990BAKTERIJSKI PALEŽ (ERWINIA AMYLOVORA) AKTUALNA OPASNOST Palež koju uzrokuje bakterija Erwinia amylovora najopasnija je bolest krušaka, ali osim krušaka mogu biti napadnuti osjetljivi kultivari jabuka, dunja, te veliki broj raznih vrsta ukrasnog grmlja iz porodice ruža.
