Increased Pho regulon activation correlates with decreased virulence of an avian pathogenic Escherichia coli O78 strain.
Avian pathogenic Escherichia coli (APEC) strains are associated with respiratory infections, septicemia, cellulitis, peritonitis, and other conditions, since colibacillosis manifests in many ways. The Pho regulon is jointly controlled by the two-component regulatory system PhoBR and by the phosphate-specific transport (Pst) system. To determine the specific roles of the PhoBR regulon and the Ps...
متن کاملCharacterization of the contribution to virulence of three large plasmids of avian pathogenic Escherichia coli chi7122 (O78:K80:H9).
Despite the fact that the presence of multiple large plasmids is a defining feature of extraintestinal pathogenic Escherichia coli (ExPEC), such as avian pathogenic E. coli (APEC), and despite the fact that these bacteria pose a considerable threat to both human and animal health, characterization of these plasmids is still limited. In this study, after successfully curing APEC of its plasmids,...
متن کاملcontribution of setting to the study of characters and the main idea in e. brontes: wuthering heights and t. hardys: return of the native.
this thesis aims to adduce an unmitigated and comprehensive explication concerning the relationship of three significant elements of fiction: setting, chracter and theme. my research is basically placed on two outstanding novels of the 19th century: emily brontes wuthering heights and thomas hardys return of the native. my endeavour lies in studying the correlation among the three above-mention...
15 صفحه اولThe BarA-UvrY two-component system regulates virulence in avian pathogenic Escherichia coli O78:K80:H9.
The BarA-UvrY two-component system (TCS) in Escherichia coli is known to regulate a number of phenotypic traits. Both in vitro and in vivo assays, including the chicken embryo lethality assay, showed that this TCS regulates virulence in avian pathogenic E. coli (APEC) serotype O78:K80:H9. A number of virulence determinants, such as the abilities to adhere, invade, persist within tissues, surviv...
متن کاملFull Sequence and Comparative Analysis of the Plasmid pAPEC-1 of Avian Pathogenic E. coli χ7122 (O78∶K80∶H9)
BACKGROUND Extra-intestinal pathogenic E. coli (ExPEC), including Avian Pathogenic E. coli (APEC), are very diverse. They cause a complex of diseases in Human, animals, and birds. Even though large plasmids are often associated with the virulence of ExPEC, their characterization is still in its infancy. METHODOLOGY/PRINCIPAL FINDINGS We fully sequenced and analyzed the large plasmid pAPEC-1 (...
