Comparative study of hemolytic activity of Bordetella species
Iranian Journal of Microbiology, 2009 Background and objectives: Bordetella species colonize the respiratory tract of mammals and thereby cause the whooping cough. Most of the species produce adenylate cyclase - a toxin ( hemolysin ) responsible for increasing intracellular cyclic AMP (cAMP)

Lonidamine, a Novel Modulator for the BvgAS System of Bordetella Species. [PDF]
Microbiol ImmunolABSTRACTThe Gram‐negative bacteria Bordetella pertussis, B. parapertussis, and B. bronchiseptica cause respiratory diseases in various mammals. They share the BvgAS two‐component system, which regulates the phenotypic conversion between the virulent Bvg+ and avirulent Bvg– phases.

Bordetella pertussis and Bordetella parapertussis: two immunologically distinct species [PDF]
Infection and Immunity, 1993 Bordetella pertussis and Bordetella parapertussis are closely related species. Both are responsible for outbreaks of whooping cough in humans and produce similar virulence factors, with the exception of pertussis toxin, specific to B. pertussis. Current pertussis whole-cell vaccine will soon be replaced by acellular vaccines containing major adhesins ...

Characterization of fimbrial subunits from Bordetella species [PDF]
Microbial Pathogenesis, 1987 Using antisera raised against serotype 2 and 3 fimbrial subunits from Bordetella pertussis, serologically related polypeptides were detected in Bordetella bronchiseptica, Bordetella parapertussis and Bordetella avium strains. The two B. pertussis fimbrial subunits, and three of the serologically related B.

The type III secreted protein BspR regulates the virulence genes in Bordetella bronchiseptica. [PDF]
PLoS ONE, 2012 Bordetella bronchiseptica is closely related with B. pertussis and B. parapertussis, the causative agents of whooping cough. These pathogenic species share a number of virulence genes, including the gene locus for the type III secretion system (T3SS ...

Biological Properties of Lipopolysaccharides from Bordetella Species [PDF]
Journal of General Microbiology, 1990 Biological activities of lipopolysaccharides (LPS) extracted from Bordetella pertussis, B. parapertussis and B. bronchiseptica were compared with those of Escherichia coli LPS. The LPS preparations from B. pertussis showed biological activities comparable to those of E. coli LPS in terms of lethal toxicity in galactosamine-sensitized mice, pyrogenicity

Virulence factor secretion and translocation by Bordetella species [PDF]
Current Opinion in Microbiology, 2009 Here we review the Bordetella virulence secretome with an emphasis on factors that translocate into target cells. Recent advances in understanding the functions of adenylate cyclase toxin, a type 1 secretion system (T1SS) substrate, and pertussis toxin, a type IV secretion system (T4SS) substrate, are briefly described and a compilation of additional ...

Frontiers in Microbiology, 2019 Animal and human pathogens of the genus Bordetella are not commonly considered to be intracellular pathogens, although members of the closely related classical bordetellae are known to enter and persist within macrophages in vitro and have anecdotally ...

Morphology of cells and hemagglutinogens of Bordetella species: resolution of substructural units in fimbriae of Bordetella pertussis [PDF]
Infection and Immunity, 1983 The morphology of cells and the hemagglutinogens isolated from cultures of Bordetella pertussis, Bordetella bronchiseptica, and Bordetella parapertussis were studied by electron microscopy with the negative-staining technique. Cells of all three species had long, thin (3 nm thick), peritrichously arranged fimbriae on the cell surface.

Molecular evolution of the two-component system BvgAS involved in virulence regulation in Bordetella. [PDF]
PLoS ONE, 2009 The whooping cough agent Bordetella pertussis is closely related to Bordetella bronchiseptica, which is responsible for chronic respiratory infections in various mammals and is occasionally found in humans, and to Bordetella parapertussis, one lineage of
