| purification and subunit heterogeneity of pili of bordetella bronchiseptica. | pili were isolated and purified from bordetella bronchiseptica. electron microscopic observations revealed that pili are ubiquitous in this species. the occurrence of pili and flagella appeared to correlate with growth phase and colonial morphology. pili were about 3 to 4 nm in diameter and morphologically similar to pili isolated from other gram-negative bacteria. internal core structure was not evident. sodium dodecyl sulfate-polyacrylamide gel electrophoresis of purified pili showed that up t ... | 1986 | 2867974 |
| characteristic cellular fatty acid composition and an ornithine-containing lipid as a new type of hemagglutinin in bordetella pertussis. | the fatty acid composition of the total extractable cellular lipids of bordetella pertussis was very characteristic and was mostly hexadecenoic and hexadecanoic acids (90%) in a ratio of about 1:1. the fatty acid composition of bordetella parapertussis and bordetella bronchiseptica differed from that of b. pertussis. the two species were distinguished by the fatty acid composition of cell-bound lipids. the ornithine-containing lipid was characteristic of the genus bordetella and its main structu ... | 1985 | 2872110 |
| bordetella adenylate cyclase: a genus specific protective antigen and virulence factor. | most of the adenylate cyclase (ac) present in bordetella species is localized in the outer membrane, partly exposed to the cell surface. an isolation procedure to obtain the cell-bound enzyme was applied to bordetella bronchiseptica, bordetella pertussis and bordetella parapertussis. passive transfer of b. bronchiseptica anti-ac antibody, either in the form of monoclonal antibody or antibody transferred to offspring from female mice previously immunized with immunopurified b. bronchiseptica ac, ... | 1985 | 2872113 |
| increase in intradermal vascular permeability caused by pertussis toxin from bordetella pertussis. | rabbits that were injected intradermally with pertussis toxin (pt), produced from bordetella pertussis, showed slight edema and erythema at the injection sites, but not hemorrhage nor necrosis. the edema lesions were stained blue by the intravenous injection of pontamine sky blue 6b dye, suggesting that pt caused increased vascular permeability, similarly to the permeability factor (pf) of cholera toxin. the reaction of the pf of pt could be determined by measuring the diameter of the blue area. ... | 1987 | 2890084 |
| evolutionary relationships in the genus bordetella. | the nucleotide sequence of the pertussis toxin operon of bordetella pertussis, bordetella parapertussis and bordetella bronchiseptica, has shown that the last two species contain many common mutations and are likely to derive from a common ancestor (aricò and rappuoli, 1987). to elucidate further the evolutionary relationships between the bordetella species, we have cloned and sequenced the promoter region and the gene coding for the s1 subunit of pertussis toxin from additional b. pertussis str ... | 1987 | 2896289 |
| positive regulation of pertussis toxin expression. | although the genus bordetella contains several closely related species, pertussis toxin (pt) is produced only by phase i bordetella pertussis. in this work we have studied the regulation of expression of the pt operon and investigated why pt is produced by phase i and not by phase iii b. pertussis despite the presence of the pt genes. we have constructed a vector for bordetella species that contains the pt promoter fused to the coding region of the chloramphenicol acetyltransferase (cat) gene, a ... | 1988 | 2897691 |
