Analysis of BvgA Activation of the Pertactin Gene Promoter in Bordetella pertussis
Kinnear, Susan M., Boucher, Philip E., Stibitz, Scott, Carbonetti, Nicholas H.
Bordetella pertussis, the causative agent of whooping cough, regulates expression of its virulence factors via a two-component signal transduction system encoded by the bvg regulatory locus. It has...
Genomic Plasticity in Natural Populations of Bordetella pertussis
Stibitz, Scott, Yang, Mei-Shin
We determined the genomic organization of 14 clinical strains of Bordetella pertussis isolated over an 18-month period in Alberta, Canada. The maps of these 14 strains, while demonstrating general...

The BvgA-BvgS two-component signal transduction system regulates expression of virulence factors in Bordetella pertussis. The BvgA response regulator activates transcription by binding to target...
Characterization of the bvgR Locus of Bordetella pertussis
Merkel, Tod J., Barros, Cassia, Stibitz, Scott
Bordetella pertussis, the causative agent of whooping cough, produces a wide array of factors that are associated with its ability to cause disease. The expression and regulation of these virulence...
The effects of short deletions of the C terminus of the BvgA response regulator protein of the BvgAS two-component system were examined in Bordetella pertussis. When present as a single copy in the...
The insertion sequence IS481 and its isoform IS1002 have been observed to transpose into the bvgAS locus of Bordetella pertussis, for which the DNA sequence has previously been determined. Upon...
Contribution of Regulation by the bvg Locus to Respiratory Infection of Mice by Bordetella pertussis
Merkel, Tod J., Stibitz, Scott, Keith, Jerry M., Leef, Mary, Shahin, Roberta
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...
Analysis of bvgR Expression in Bordetella pertussis
Merkel, Tod J., Boucher, Philip E., Stibitz, Scott, Grippe, Vanessa K.
Bordetella pertussis, the causative agent of whooping cough, produces a wide array of factors that are associated with its ability to cause disease. The expression and regulation of these virulence...
Routine Markerless Gene Replacement in Bacillus anthracis
Janes, Brian K., Stibitz, Scott
An improved genetic tool suitable for routine markerless allelic exchange in Bacillus anthracis has been constructed. Its utility was demonstrated by the introduction of insertions, deletions, and...

O Antigen Protects Bordetella parapertussis from Complement▿
Goebel, Elizabeth M., Wolfe, Daniel N., Elder, Kelly, Stibitz, Scott, Harvill, Eric T.
Bordetella pertussis, a causative agent of whooping cough, expresses BrkA, which confers serum resistance, but the closely related human pathogen that also causes whooping cough, Bordetella...
Verma, Anita, Wagner, Leslie, Stibitz, Scott, Nguyen, Nga, Guerengomba, Flor, Burns, Drusilla L.
The cytotoxic activity of lethal factor (LF), a critical reagent used in the cell-based lethal toxin neutralization assay to assess anthrax vaccines, was shown to depend on the identity of its...
Loving, Crystal L., Khurana, Taruna, Osorio, Manuel, Lee, Gloria M., Kelly, Vanessa K., Stibitz, Scott, ...
Anthrax toxins significantly contribute to anthrax disease pathogenesis, and mechanisms by which the toxins affect host cellular responses have been identified with purified toxins. However, the...
