| cloning of campylobacter jejuni genes required for leucine biosynthesis, and construction of leu-negative mutant of c. jejuni by shuttle transposon mutagenesis. | campylobacter jejuni is a gram-negative pathogen responsible for diarrhoeal diseases in humans. to date, very little is known about the genetic organization and molecular biology of this microorganism. the cosmid vector phc79 was used to construct a genomic library from the total genomic dna of c. jejuni strain c31 in escherichia coli and recombinant cosmids capable of complementing the auxotrophic defect in leucine biosynthesis of e. coli hb101 were identified. three of 400 clones tested were f ... | 1992 | 1322552 |
| differentiation between thermophilic campylobacter species by species-specific antibodies. | the four species of thermophilic campylobacters, campylobacter jejuni, c. coli, c. upsaliensis and c. lari, are difficult to distinguish from each other because of their lack of reactivity in many conventional biochemical and physiological tests. those tests which do discriminate sometimes give discordant results. species-specific antibody preparations (aps), capable of discriminating between the thermophilic campylobacter species by dot-elisa, were raised by inoculation of mice with partially p ... | 1992 | 1322880 |
| inflammatory-demyelinating polyneuropathies. | recent advances in the pathogenesis and management of guillain-barré syndrome (gbs) and chronic inflammatory demyelinating polyneuropathy (cidp) are presented. these diseases are both diagnosable and treatable. the role of campylobacter infection preceding gbs and the use of intravenous immunoglobulin to treat cidp are discussed. | 1992 | 1323748 |
| e-test: a new technique for antimicrobial susceptibility testing for periodontal microorganisms. | the purpose of the study was to validate the epsilometer test (e-test) method for antimicrobial susceptibility testing of selected periodontopathic microorganisms using the agar dilution method as a standard. the e-test has been developed to provide a direct quantification of antimicrobial susceptibility of microorganisms. the device consists of a predefined, continuous, and exponential gradient of antibiotic concentrations immobilized along a rectangular plastic test strip. after 48 hours incub ... | 1992 | 1324301 |
| synergistic effect of pyrophosphate and sodium dodecyl sulfate on periodontal pathogens. | our previous studies have shown that pyrophosphate (ppi), the anticalculus component of tartar-control dentifrices, inhibits the growth of organisms associated with coronal and root surface caries. the purposes of this investigation were to: 1) determine if periodontal pathogens are similarly susceptible to the growth-inhibitory properties of ppi; and 2) determine if combinations of pyrophosphate-sodium dodecyl sulfate (ppi-sds) inhibit growth synergistically. porphyromonas gingivalis, actinobac ... | 1992 | 1324304 |

| dna probe and enzyme analysis in periodontal diagnostics. | recent research in periodontology has indicated that a finite number of bacterial species are associated with periodontal disease. this has generated the hypothesis that periodontal disease is essentially an infection due to one or more of the putative periodontopathogens; i.e., the specific plaque hypothesis (sph). this microbial specificity paradigm has already changed the way researchers and some clinicians view periodontal disease. the clinician must heed several cautions signs, however, if ... | 1992 | 1336048 |
| immunological cross-reactivity between outer membrane pore proteins of campylobacter jejuni and escherichia coli. | immunocrossreactivity between the major outer membrane protein (momp) of campylobacter jejuni 85h and the ompc porin of escherichia coli k-12 was observed. these results indicate that a common antigenic domain is conserved in both momp and ompc. this antigenic region is detected only after a 96 degrees c treatment suggesting that it is buried in the native conformation of the respective porins. in addition, differences were observed between the major outer membrane proteins from various c. jejun ... | 1992 | 1337053 |
