Using 80 gastric biopsy specimens from patients with various gastroduodenal diseases, the isolation rate of H. pylori and urease activity of the biopsy specimens were examined. The sensitivity and specificity of the rapid urease test was 84.6% and 75.9%, respectively, for the cultivation of H. pylori. The mean number of H. pylori detected in urease-positive(More)
Mtissbauer measurement, chemical analysis (ratioof Fez+ to total Fe content), analyses ofthe rotational hysteresis loss (Wr) and the magnetic viscosity coefficient (Sv) for bacterial magnetic particles covered with organic thin films (BMPs) were investigated and compared with the results for Fes04 h e particles prepared by a chemical coprecipitation method.(More)
The adhesion of Vibrio cholerae O1 strains to human intestinal epithelial cell, Intestine 407, was analyzed by flow cytometer. According to positive percentages of Intestine 407 cells adhered by V. cholerae, two groups of V. cholerae strains were classified as follows: more adhesive (more than 50%), less adhesive (less than 50%) strains. In addition, the(More)
We attempted to obtain the monoclonal antibody specific for the N-linked complex-type sialo-oligosaccharide in glycoproteins. We first synthesized a chimeric immunoantigen having an N-linked complex-type of oligosaccharide of glycopeptide, which was bound to a p-formylphenyl compound and conjugated with phosphatidylethanolamine dimyristoyl using the(More)
Magnetospirillum sp. AMB-l is a freshwater magnetic bacterium which synthesizes intracellular particles of magnetite (Fe304). A genomic DNA fragment required for synthesis of magnetic particles, was previously isolated from a non-magnetic transposon Tn5 mutant. We have determined the complete nucleotide sequence of this fragment. The 2975 bp region contains(More)
