AbstractShiga toxin (Stx)‐producing Escherichia coli (STEC) strains isolated from wild deer in Japan were examined. A total of 43 fecal samples were collected 4 times from 4 different sites around Obihiro City, Hokkaido, Japan, in June and July 1997. Seven STEC strains were isolated by PCR screening, all of them were confirmed by ELISA an...... hiện toàn bộ
Genotypic Analysis of the 5′‐Untranslated Region of a Pestivirus Strain Isolated from Human LeucocytesMicrobiology and Immunology - Tập 41 Số 10 - Trang 829-834 - 1997
Massimo Giangaspero, Ryô Harasawa, A. Verhulst
AbstractThe 5′‐untranslated genomic region of the pestivirus strain Europa, originated in human leucocytes and previously identified as bovine diarrhea virus (BVDV), was amplified by reverse transcription‐PCR and sequenced. Analyses based on primary nucleotide sequence homology and on secondary palindromic sequence structures characteristic to genotypes revealed th...... hiện toàn bộ
Mechanism of Selective Inhibition of Respiratory Syncytial Virus by a Benzodithiin Compound (RD3–0028)Microbiology and Immunology - Tập 45 Số 7 - Trang 531-537 - 2001
Kenji Sudo, Kenji Konno, Wataru Watanabe, Shirô Shigeta, Tomoyuki Yokota
AbstractRD3–0028, a compound with a benzodithiin structure, was found to be a potent inhibitor of respiratory syncytial virus (RSV) replication. Its action is specific; no activity is seen against influenza A virus, measles virus, herpes simplex virus type 1 or 2, or human cytomegalovirus. A time‐dependent drug addition experiment indicated that the antiviral activ...... hiện toàn bộ
DNA from Bacteria, but Not from Vertebrates, Induces Interferons, Activates Natural Killer Cells and Inhibits Tumor GrowthMicrobiology and Immunology - Tập 36 Số 9 - Trang 983-997 - 1992

AbstractThe nucleic acid fraction from cells of 6 species of bacterium and 2 kinds of vertebrate, calf and salmon, was extracted and purified by the same procedures as described previously. When the spleen cells from BALB/c mice were incubated with the nucleic acid fraction from either of the bacteria, natural killer (NK) activity of the cells was remarkably elevat...... hiện toàn bộ
Antibacterial Activity of Hydrolyzable Tannins Derived from Medicinal Plants against Helicobacter pyloriMicrobiology and Immunology - Tập 48 Số 4 - Trang 251-261 - 2004

AbstractHelicobacter pylori is a major etiological agent in gastroduodenal disorders. In this study, we isolated 36 polyphenols and 4 terpenoids from medicinal plants, and investigated their antibacterial activity against H. pylori in vitro. All hydrolyzable tannins tested demonstrated promising antibacterial ac...... hiện toàn bộ
