regulation of the f plasmid tray promoter in escherichia coli by host and plasmid factors.	f plasmid dna transfer (tra) gene expression in escherichia coli is regulated by chromosome- and f-encoded gene products. to study the relationship among these regulatory factors, we constructed low-copy plasmids containing a phi(tray'-'lacz)hyb gene that couples beta-galactosidase and lac permease synthesis to the f plasmid tray promoter. wild-type transformants maintained high levels of beta-galactosidase over a broad range of culture densities. primer extension analysis of tra mrna from f'lac ...	1991	2002497
microbiological and immunological aspects of experimental periodontal disease in rats: a review article.	animal models in which microbiological and immunological aspects of periodontal disease can be studied prospectively seem well warranted. the rat bears much resemblance to man with respect to periodontal anatomy, development and composition of dental plaque, histopathology of periodontal lesions, and basic immunobiology. furthermore, reproducible methods are available for assessment of periodontal disease in rats, and detectable periodontal destruction can be induced in a few weeks in these anim ...	1991	2002433
isolation and purification of bacteriocin from prevotella intermedia (bacteroides intermedius).	thirty-three out of 46 strains of prevotella intermedia (bacteroides intermedius) isolated from gingival deposits of patients with adult periodontitis possessed the ability to inhibit growth of p. intermedia strain atcc 25611, and 6 of the 33 showed strong inhibitory activity. thirteen isolates did not have the ability to inhibit the growth of p. intermedia strain atcc 25611. an inhibition factor from one of the isolates, p. intermedia th14 which had strong inhibition, was purified and character ...	1991	1920011
in vitro killing of actinobacillus actinomycetemcomitans and capnocytophaga spp. by human neutrophil cathepsin g and elastase.	the purpose of this study was to compare the killing of actinobacillus actinomycetemcomitans with that of capnocytophaga spp. by purified cathepsin g and elastase in vitro. both were sensitive to killing by purified cathepsin g, but only the capnocytophaga spp. were killed by elastase. killing by cathepsin g exhibited logarithmic kinetics, was enhanced slightly by alkaline ph, and was enhanced greatly under hypotonic conditions. treatment of cathepsin g with diisopropyl fluorophosphate significa ...	1991	1879926
