cloning and sequencing of the structural gene for the porin protein of bordetella pertussis.bordetella pertussis produces a porin protein which is a prominent outer membrane component found in both virulent and avirulent strains. n-terminal amino acid analysis of purified b. pertussis porin was performed and this amino acid sequence was used to design an oligonucleotide that was then utilized to screen a lambda gt11 library containing randomly sheared fragments of dna from b. pertussis strain 347. one clone, lambda bppor, was identified and subcloned into puc18. a portion of the dna in ...19911658537
bordetella bronchiseptica isolations from the nasal cavity of pigs in relation to atrophic rhinitis.the occurrence of bordetella bronchiseptica and atrophic rhinitis was studied during a one-year period in four danish sow herds. in three of the heards, the epidemiological studies revealed a relation between the occurrence of b. bronchiseptica in 3--10-week-old pigs and the presence and severity of atrophic rhinitis at slaughter. in the fourth herd no such relation was found.19761250685
construction of minitransposons for constitutive and inducible expression of pertussis toxin in bvg-negative bordetella bronchiseptica.appropriately detoxified pertussis toxin (pt) of bordetella pertussis is considered to be an essential component of new-generation whooping cough vaccines, but the development of a procedure to obtain high levels of purified toxin has been and continues to be a major difficulty. to produce a system enabling the biological separation of pt from other virulence determinants of b. pertussis and the attainment of high yields of the toxin, minitransposons containing the pt operon were constructed and ...19911682257
expression of bordetella pertussis fimbrial (fim) genes in bordetella bronchiseptica: fimx is expressed at a low level and identify the elements involved in bordetella pertussis fimbriae regulation and to determine whether fimx is an expressed gene, the promoter regions of fimx, fim2 and fim3 from strain bpsa1 were isolated and linked to the promoterless cat gene in plafr2. by following cat activity in bordetella bronchiseptica vir+ and vir- strains we established that the fimx promoter, like those for fim2 and fim3, is active, although at a low level, and vir-regulated. this suggests that the fimx protein might ...19911684407
production of recombinant bordetella pertussis serotype 2 fimbriae in bordetella parapertussis and bordetella bronchiseptica: utility of escherichia coli gene expression signals.serotype-specific fimbriae of bordetella pertussis are considered potential components of new-generation vaccines against whooping cough. attempts to characterize fimbriae, and indeed other virulence determinants, produced by b. pertussis have been frustrated on one hand by low yields from b. pertussis itself and on the other by an inability to produce native recombinant products in escherichia coli. in order to try to circumvent this problem, we have examined the expression of b. pertussis sero ...19911708358
virulence of streptococcus suis type 2 strains in newborn germfree pigs depends on determine whether the virulence of streptococcus suis type 2 is associated with the phenotype of the strain, we infected newborn germfree pigs with 10 strains of s. suis type 2 categorized by three phenotypes. in an earlier study, the phenotypes were distinguished by the presence or absence of the muramidase-released protein (mrp) and an extracellular factor (ef) and were designated mrp+ ef+, mrp+ ef- and mrp- ef-. pigs were first inoculated with bordetella bronchiseptica to predispose them t ...19921730489
a vir-repressed gene of bordetella pertussis is required for virulence.coordinate regulation of gene expression in bordetella pertussis is controlled by the products of the vir locus, bvga and bvgs. in the presence of modulating signals such as mgso4 and nicotinic acid, expression of vir-activated genes (vag) is reduced, while expression of vir-repressed genes (vrg) is maximal. we have cloned one of these vir-repressed genes, vrg-6, in escherichia coli. dna sequencing has shown that vrg-6 is contained on a single ecori restriction endonuclease fragment and is predi ...19921730491
