Transfer of Two Burkholderia and An Alcaligenes Species to Ralstonia Gen. Nov.Abstract Based on the results of phenotypic characterization, cellular lipid and fatty acid analysis, phylogenetic analysis of 16S rDNA nucleotide sequences and rRNA‐DNA hybridization, Burkholderia pickettii, Burkholderia solanacearum and Alcaligenes eutrophus are transferred to the new genus Ralston... ... hiện toàn bộ

DNA from Bacteria, but Not from Vertebrates, Induces Interferons, Activates Natural Killer Cells and Inhibits Tumor GrowthAbstract The 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 pyloriAbstract Helicobacter 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...

Interleukin‐17 as an Effector Molecule of Innate and Acquired Immunity against InfectionsAbstract Interleukin (IL)‐17 is a proinflammatory cytokine which induces differentiation and migration of neutrophils through induction of cytokines and chemokines including granulocyte‐colony stimulating factor and CXCL8/IL‐8. IL‐17‐producing CD4+ T cells (Th17) have pivotal role in pathogenesis of autoimmune diseases. IL‐17 is also involved in... ... hiện toàn bộ

Antimicrobial Activity and Stability to Proteolysis of Small Linear Cationic Peptides with D‐Amino Acid SubstitutionsAbstract Antimicrobial peptides contribute to innate host defense against a number of bacteria and fungal pathogens. Some of antimicrobial synthetic peptides were systemically administered in vivo ; however, effective protection has so far not been obtained because the effective dose of peptides in vivo seems to b... ... hiện toàn bộ

Mechanisms of Action of Corilagin and Tellimagrandin I That Remarkably Potentiate the Activity of β‐Lactams against Methicillin‐Resistant Staphylococcus aureusAbstract Corilagin and tellimagrandin I are polyphenols isolated from the extract of Arctostaphylos uvaursi and Rosa canina L. (rose red), respectively. We have reported that corilagin and tellimagrandin I remarkably reduced the minimum inhibitory concentration (MIC) of β‐lactams in methicillin‐resistant ... hiện toàn bộ

Lambda‐Toxin of Clostridium perfringens Activates the Precursor of Epsilon‐Toxin by Releasing Its N‐ and C‐Terminal PeptidesAbstract The effect of γ‐toxin, a thermolysin‐like metalloprotease of Clostridium perfringens , on the inactive ε‐prototoxin produced by the same organism was examined. When the purified ε‐prototoxin was incubated with the purified γ‐toxin at 37 C for 2 hr, the 32.5‐kDa ε‐prototoxin was processed into a 30.5‐kDa polypeptide, as determined b... ... hiện toàn bộ

Anti‐quorum sensing activity of Psidium guajava L. flavonoids against Chromobacterium violaceum and Pseudomonas aeruginosa PAO1ABSTRACT Psidium guajava L., which has been used traditionally as a medicinal plant, was explored for anti‐quorum sensing (QS) activity. The anti‐QS activity of the flavonoid (FL) fraction of P. guajava leaves was determined using a biosensor bioassay with Chromobacterium viol...

The Relationship between Microbiota and Polyamine Concentration in the Human Intestine: A Pilot StudyAbstract The fecal microbiota of 10 hospitalized elderly subjects and 14 healthy adults were analyzed by terminal‐restriction fragment length polymorphism (T‐RFLP) analysis using Hha I, Msp I, Hae III, and Alu I, as well as fecal polyamine (PA) concentration. The ... ... hiện toàn bộ

Anti‐inflammatory properties of intestinal Bifidobacterium strains isolated from healthy infantsABSTRACT Certain Bifidobacterium strains have been shown to inhibit inflammatory responses in intestinal epithelial cells. However, the precise mechanisms of these effects, including the chemical nature of the active compounds, remain to be elucidated. Here partial characterization of the anti‐inflammatory properties of Bifido... ... hiện toàn bộ
