The molecular basis of resistance and susceptibility of host plants to fire blight, a major disease threat to pome fruit production globally, is largely unknown. RNA-sequencing data from challenged and mock-inoculated flowers were analyzed to assess the susceptible response of apple to the fire blight pathogen Erwinia amylovora. In presence of the pathogen 1,080 transcripts were differentially ...

conclusions thirty-three bacterial strains; 10 strains of e. coli, 10 strains of s. flexneri, 3 strains s. sonnei, 2 strains of s. serovar newport, and 7 strains of p. aeruginosa, were isolated and identified from nile water and ground water in sohag governorate. the prevalence of enteric bacteria in water sources in studying area was considerable. no clear or distinct correlation could be conc...

Introduction:  The aim of the present study was to investigate the presence and the frequency of EAEC as etiologic agent of diarrhea in Shiraz. Enteroaggregative E. coli (EAEC) is increasingly recognized as a cause of often persistent diarrhoea in children and adults in both developing and developed countries, and have been identified as the cause of several outbreaks worldwide.   Materials and...

ABSTRACT The aggressiveness of an extensive collection of strains of Erwinia amylovora was analyzed using immature fruit and detached pear flower assays under controlled environmental conditions. The analysis was performed by means of a quantitative approach based on fitting data to mathematical models that relate infection incidence to pathogen dose and time. Probit and hyperbolic saturation m...

conclusions the results of this study indicated that more than 90% of e. coli isolates harbored the fimh gene. the high binding ability of fimh could result in the increased pathogenicity of e. coli; thus, fimh could be used as a possible diagnostic marker and/or vaccine candidate. materials and methods a total of 140 isolated e. coli strains from patients with uti were identified using biochem...

This work describes a medium-based screening method for selecting microbial biocontrol agents against Erwinia amylovora based on the degradation of a specific growth factor. Erwinia amylovora, the causal agent of the devastating fire blight disease, requires nicotinic acid or nicotinamide as an essential growth factor. Potential biocontrol agents are either selected for antimicrobial production...

Plants are host to a large amount of pathogenic bacteria. Fire blight, caused by the bacterium Erwinia amylovora, is an important disease in Rosaceae. Pathogenicity of E. amylovora is greatly influenced by the production of exopolysaccharides, such as amylovoran, and the use of the type III secretion system, which enables bacteria to penetrate host tissue and cause disease. When infection takes...
