Proteomics-Identified Bvg-Activated Autotransporters Protect against Bordetella pertussis in a Mouse Model
Pertussis is a highly infectious respiratory disease of humans caused by the bacterium Bordetella pertussis. Despite high vaccination coverage, pertussis has re-emerged globally. Causes for the re-emergence of pertussis include limited duration of protection conferred by acellular pertussis vaccines (aP) and pathogen adaptation. Pathogen adaptations involve antigenic divergence with vaccine str...
متن کاملContribution of regulation by the bvg locus to respiratory infection of mice by Bordetella pertussis.
Whooping cough is an acute respiratory disease caused by the small, gram-negative bacterium Bordetella pertussis. B. pertussis expresses several factors that contribute to its ability to cause disease. These factors include surface-associated molecules, which are involved in the adherence of the organism to respiratory epithelial cells, as well as several extracellular toxins that inhibit host ...
متن کاملDifferential regulation of Bvg-activated virulence factors plays a role in Bordetella pertussis pathogenicity.
Bordetella pertussis, the causative agent of whooping cough, regulates expression of many virulence factors via a two-component signal transduction system encoded by the bvgAS regulatory locus. It has been shown by transcription activation kinetics that several of the virulence factors are differentially regulated. fha is transcribed within 10 min following a bvgAS-inducing signal, while prn is...
متن کاملAutogenous regulation of the Bordetella pertussis bvgABC operon.
The bvgABC operon of the bacterial pathogen Bordetella pertussis encodes a sensory transduction system that regulates the expression of several virulence genes in response to environmental stimuli. In this study we have examined the transcriptional regulation of the bvgABC operon. Transcriptional bvg::lacZYA fusions in Escherichia coli show that the bvgABC operon is autogenously activated. Auto...
متن کاملAn improved recombination-based in vivo expression technology-like reporter system reveals differential cyaA gene activation in Bordetella species.
Bordetella pertussis and Bordetella bronchiseptica rely on the global two-component regulatory system BvgAS to control expression of distinct phenotypic phases. In the Bvg(-) phase, expression of vrg genes, including those required for motility in B. bronchiseptica, is activated and genes encoding virulence factors are not expressed. Conversely, in the Bvg(+) phase, genes encoding virulence fac...
