| actinobacillus actinomycetemcomitans immunosuppressive protein is a member of the family of cytolethal distending toxins capable of causing a g2 arrest in human t cells. | we have previously shown that actinobacillus actinomycetecomitans produces an immunosuppressive factor (isf) capable of impairing human lymphocyte function by perturbing cell cycle progression. we now report that isf is the product of the cdtb gene, one of three genes encoding the family of cytolethal distending toxins (cdt). the isf polypeptide exhibits >/=95% identity with hemophilus ducreyi cdtb protein and </=60% homology with escherichia coli or campylobacter jejuni cdtb. pretreatment of ph ... | 1999 | 10202019 |
| predictive fluorescent amplified-fragment length polymorphism analysis of escherichia coli: high-resolution typing method with phylogenetic significance. | the fluorescent amplified-fragment length polymorphism (faflp) assay potentially amplifies a unique set of genome fragments from each bacterial clone. it uses stringently hybridizing primers which carry a fluorescent label. precise fragment sizing is achieved by the inclusion of an internal size standard in every lane. therefore, a unique genotype identifier(s) can be found in the form of fragments of precise size or sizes, and these can be generated reproducibly. in order to evaluate the potent ... | 1999 | 10203470 |
| serological discrimination of dogs infected with gastric helicobacter spp. and uninfected dogs. | characterization of the humoral immune responses of people to helicobacter pylori infection has facilitated the investigation of the host response to bacterial virulence factors and the development of sensitive and specific diagnostic tests. dogs are commonly infected with gastric helicobacter spp., but the presence of multiple helicobacter spp. and possible coinfection in individual dogs have complicated serological evaluation. evaluation of the antigenic homology of helicobacter spp. revealed ... | 1999 | 10203471 |
| cytolethal distending toxin genes in campylobacter jejuni and campylobacter coli isolates: detection and analysis by pcr. | campylobacter jejuni produces a toxin called cytolethal distending toxin (cdt). knowledge of the prevalence and homogeneity of campylobacter sp. cdt genes is incomplete. in this work, we identified four pcr primer pairs that collectively amplified cdt genes in all of the c. jejuni and campylobacter coli strains tested. restriction analyses of the cdt pcr products showed clear differences between the cdt genes of these two species, yet there were few heterogeneities noted between members of the s ... | 1999 | 10203548 |
| cloning, sequencing and molecular analysis of the campylobacter jejuni groesl bicistronic operon. | the groesl bicistronic operon from the enteric pathogen campylobacter jejuni was cloned and sequenced. it consists of two orfs encoding proteins with molecular masses of 9.5 and 57.9 kda, which showed a high degree of homology to other bacterial groes and groel proteins. northern blot analysis suggested that the groesl operon is transcribed as a bicistronic mrna, and its steady-state level was markedly increased after temperature upshift. by primer extension assay, one potential transcription st ... | 1999 | 10206714 |
| differentiation of campylobacter coli and c. jejuni by length and dna sequence of the 16s-23s rrna internal spacer region. | the internal spacer region (isr) between the 16s and 23s rrna genes of campylobacter was investigated by pcr fragment length typing and dna sequencing of clinical and chicken wild-type isolates. pcr fragment length typing showed one fragment of 859 nt in length for the 12 strains of campylobacter coli investigated. thirty-six of the campylobacter jejuni subsp. jejuni strains possessed one fragment, which varied in size between 727 and 802 nt. three strains showed two fragments between 501 and 92 ... | 1999 | 10206715 |
| the use of hipo, encoding benzoylglycine amidohydrolase (hippuricase), as a reporter of gene expression in campylobacter coli. | a novel integrative promoter probe vector which utilizes the campylobacter jejuni hipo gene as a reporter of gene expression was developed as a genetic tool in campylobacter coli. the utility of the system was demonstrated by coupling expression of the hipo reporter to the promoters of flaa, flab and kata. subsequently, expression of these genes could be monitored accurately from chromosomally-borne transcriptional fusions using a simple non-destructive colorimetric assay. the system should serv ... | 1999 | 10212441 |
