bacteriological variation among bordetella bronchiseptica isolates from dogs and other species.bacteriological properties of 50 isolates of bordetella bronchiseptica were compared. phase variation, which involved colonial morphology and its associated characters of hemagglutination, hemolysis, acriflavine agglutination; crystal violet staining, flagellation, and fimbriation, occurred among these isolates. organisms representing the three observed morphotypes did not have different growth rates, nor were any differences in their bacteriological characteristics observed after repeated subcu ...1977858784
biochemical properties of a penicillin beta-lactamase mediated by r factor from bordetella bronchiseptica.the beta-lactamase specified by an r(te16) plasmid in bordetella bronchiseptica was purified 200-fold by carboxymethyl-sephadex column chromatography and electrofocusing. the enzyme has a molecular weight of 46,000 +/- 3,000 and an isoelectric point of 8.3 and was highly active against phenethicillin, oxacillin, and propicillin. the enzyme activity was inhibited by sodium chloride but not by ferrous ion. the maximal enzyme activity to benzylpenicillin was observed at ph 7.0 to 7.5 and at 40 c. i ...1975241286
a selective medium facilitating the isolation and recognition of bordetella bronchiseptica in pigs.a medium was developed that in most instances allowed the isolation from pigs of bordetella (alcaligenes) bronchiseptica in pure, or virtually pure, culture from such sites as the nasal cavity, which contains many other bacteria. if not suppressed, some of the latter can inhibit, sometimes completely, the growth of the bordetellae on artificial media. besides being markedly selective, the new medium is simple to prepare, reasonably cheap and practically noninhibitory to b bronchiseptica. this or ...197942958
some factors influencing the haemolysis of bordetella bronchiseptica.strain-dependent variations in the ability of bordetella bronchiseptica to produce haemolysis on solid media exist. haemolysis is strongest at an acid reaction and will not take place if the reaction is too alkaline. peptone and glutamine inhibit haemolysis and favour growth. the vigorous growth rapidly produced an alkaline reaction which inhibits the haemolysis.19765844
the effect of a respiratory tract infection on histamine-induced changes in lung mechanics and irritant receptor discharge in dogs.the effects of intravenously administered histamine on total lung resistance (rl), dynamic lung compliance (cdyn), and the discharge of lung irritant receptors have been measured in normal dogs and in dogs whose upper respiratory tract was naturally infected with the organism bordetella bronchiseptica. the resting values for rl and irritant receptor discharge were similar for the infected and control dogs, but cdyn was significantly lower in the infected group of dogs. intravenous administration ...1979507511

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 vir-regulated.to 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 phenotype.to 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
comparison of the metabolism of alveolar macrophages from humans, rats, and rabbits: phorbol myristate acetate.metabolic activities of unstimulated or stimulated ams from humans, rats, and rabbits were examined and compared in vitro. rates of oxygen consumption, chemiluminescence, and glucose (1- or 6-14c) oxidation by unstimulated ams from these three species increased following stimulation of the ams by bacteria or pma. although the absolute metabolic responses of ams from humans, rats, or wild rabbits were different, the metabolic activities from each species were nearly identical when compared on the ...1978712210
comparison of the inhibitory effect of sulfamonomethoxine and other sulfonamides on capsule formation of bordetella bronchiseptica.the inhibitory effect of sulfamonomethoxine and other sulfonamides on the capsule formation of sulfonamide-resistant bordetella bronchiseptica was investigated. all the sulfonamides having meo(-och3) groups inhibited the capsule formation of b. bronchiseptica. strong inhibition was obtained with sulfamonomethoxine. inhibition was not seen with sulfonamides having no meo groups.19921420559
