| the rna polymerases of porphyromonas gingivalis and fusobacterium nucleatum are unrelated to the rna polymerase of escherichia coli. | western blot analysis that used antisera to the e. coli core enzyme and sigma factors was used for examination of the rna polymerase of actinobacillus actinomycetemcomitans, streptococcus mutans, fusobacterium nucleatum, and porphyromonas gingivalis. both antisera reacted with proteins in a. actinomycetemcomitans and s. mutans whole-cell extracts. reactions were seen with some f. nucleatum proteins when the anti-core rna polymerase antisera were used, but the cross-reacting proteins were not of ... | 1990 | 2204641 |
| cloning of wild-type pseudomonas solanacearum phca, a gene that when mutated alters expression of multiple traits that contribute to virulence. | pseudomonas solanacearum undergoes a spontaneous mutation that pleiotropically reduces extracellular polysaccharide (eps) production, endoglucanase activity, and virulence and increases motility. we refer to the process that coordinately affects these traits as phenotype conversion (pc) and the resulting mutants as pc types. previous research with the wild-type strain aw1 suggested that inactivation of a single locus could mimic phenotype conversion (t. p. denny, f. w. makini, and s. m. brumbley ... | 1990 | 2211505 |
| regulation of fructose metabolism and polymer synthesis by fusobacterium nucleatum atcc 10953. | energy for the anaerobic growth of fusobacterium nucleatum atcc 10953 can be derived from the fermentation of sugar (fructose) or amino acid (glutamate). during growth on fructose, the cells formed large intracellular granules which after extraction yielded glucose by either acid or enzymatic hydrolysis. the endogenous polymer was subsequently metabolized, and after overnight incubation of the cells in buffer, the glucan granules were no longer detectable by electron microscopy. anaerobically, w ... | 1990 | 2211506 |
| plaque and chronic inflammatory periodontal disease. a question of ecology. | the nature of the relationship between dental plaque and chronic inflammatory periodontal disease (cipd) remains unclear, although there is no doubt that plaque is the direct cause. non-specific, specific and exogenous hypotheses have been proposed to explain plaque-host relationships. current evidence indicates that plaque is part of the natural human microflora, one of many such in nature, and that disruption of oral microbial ecology, due primarily to diet texture changes, leads to gingivitis ... | 1990 | 2212083 |
