Chemotaxes of Erwinia Carotovora Subsp. Carotovora and Erwinia Chrysanthemi

1987
The chemotactic responses of Erwinia carotovora subsp. carotovora W27 (Ecc) and E. chrysanthemi RA3 (Ech) were studied by the Adler’s capillary technique. Ecc and Ech exhibited positive chemotaxes toward a variety of sugars, amino acids and organic acids.

Effect of Erwinia Herbicola on the Motility and Chemotaxis of Erwinia Amylovora

1987
Erwiniaherbicola (112Y), a common leaf saprophyte, has been reported to inhibit apple blossom infection by Erwinia amylovora, the causal agent of fire blight of Rosaceous plants. Optimum conditions required for motility and chemotaxis in E. herbicola (112Y) were determined by the capillary assay. To better understand the saprophyte’s role in preventing

Extracellular polysaccharide of Erwinia chrysanthemi

Carbohydrate Research, 1995
Abstract The extracellular polysaccharide (EPS) produced by E. chrysanthemi pv. zeae strain SR260, a strain pathogenic to corn, has a branched hexasaccharide repeat unit consisting of a glucomannorhamnan backbone [ → 3)-β- d - Glc p-(1 → 4)-α- d - Man p-(1 → 3)-α- l - Rha p-(1 → ] and a trisaccharide side-chain [ α- l - Rha ...

Biological control of Erwinia amylovora by Erwinia herbicola

1993
A 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 ...

EXOPOLYSACCHARIDES IN PATHOGENICITY OF ERWINIA AMYLOVORA

Acta Horticulturae, 1993
The genetics of the two major exopolysaccharides of Erwinia amylovora, levan and amylovoran, were determined. Transposon mutants lacking levan synthesis were fully virulent on immature pears and showed retarded fireblight symptoms on shoots of pear seedlings.

Pectic enzymes of Erwinia carotovora

Archives of Biochemistry and Biophysics, 1953
Abstract A culture of Erwinia carotovora isolated from rotted Mexican bell pepper liberated methanol practically quantitatively from pectin when growing in a pectin medium. This phenomenon is considered to be positive evidence of pectinesterase activity. Polygalacturonase could not be demonstrated directly in the culture medium containing actively

Quorum sensing in Erwinia species

Analytical and Bioanalytical Chemistry, 2006
The term quorum sensing (QS) refers to the ability of bacteria to regulate gene expression according to the accumulation of signalling molecules that are made by every cell in the population. The erwiniae group of bacteria are often phytopathogens and the expression of a number of their important virulence determinants and secondary metabolites is ...

Endophthalmitis Caused by an Erwinia Species

Archives of Ophthalmology, 1977
A 14-year-old boy developed exogenous endophthalmitis presumably caused by an Erwinia species. To our knowledge, this is the firs reported case of endophthalmitis caused by an Erwinia species, which has been considered pathogenic for only the last ten years. The endophthalmitis developed after a piece of wood penetrated the patient's sclera.

Defective Lysogeny in Erwinia carotovora

Microbiology, 2002
The electron microscopic study of several Erwinia carotovora strains showed that the SOS-induced cells of this pectolytic phytopathogenic bacterium produce particular phage parts (tails, heads, and baseplates) but do not assemble them into fully functional phage particles. E.
