Transfer of Two Burkholderia and An Alcaligenes Species to Ralstonia Gen. Nov.
Tập 39 Số 11 - Trang 897-904 - 1995
AbstractBased 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 Ralstonia, and Ralstonia
pickettii (Ralston, Palleroni and Doudoroff 1973) comb. nov., Ralstonia
solanacear...
DNA from Bacteria, but Not from Vertebrates, Induces Interferons, Activates Natural Killer Cells and Inhibits Tumor Growth
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 elevated and the cells produced
factors...
Antibacterial Activity of Hydrolyzable Tannins Derived from Medicinal Plants against Helicobacter pylori
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 activity against H. pylori. Monomeric hydrolyzable tannins
revealed especially strong act...
Interleukin‐17 as an Effector Molecule of Innate and Acquired Immunity against Infections
Tập 51 Số 12 - Trang 1139-1147 - 2007
AbstractInterleukin (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 protective immunity against
various infections. IL‐17...
Antimicrobial Activity and Stability to Proteolysis of Small Linear Cationic Peptides with D‐Amino Acid Substitutions
Tập 46 Số 11 - Trang 741-749 - 2002
AbstractAntimicrobial 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 be very high, often close to the toxic level against the host.
Alternatively, peptides a...
Mechanisms of Action of Corilagin and Tellimagrandin I That Remarkably Potentiate the Activity of β‐Lactams against Methicillin‐Resistant Staphylococcus aureus
Tập 48 Số 1 - Trang 67-73 - 2004
AbstractCorilagin 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
Staphylococcus aureus (MRSA). In this study, we investigated the effect of
corilagin and tellim...
Lambda‐Toxin of Clostridium perfringens Activates the Precursor of Epsilon‐Toxin by Releasing Its N‐ and C‐Terminal Peptides
Tập 41 Số 7 - Trang 527-535 - 1997
AbstractThe 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 by SDS‐polyacrylamide gel electrophoresis. A mouse
lethality ...
Anti‐quorum sensing activity of Psidium guajava L. flavonoids against Chromobacterium violaceum and Pseudomonas aeruginosa PAO1
Tập 58 Số 5 - Trang 286-293 - 2014
ABSTRACTPsidium 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 violaceum CV026. Detailed investigation
of the effects of the FL‐fraction on QS‐regulated violacein production in C.
violaceum A...
The Relationship between Microbiota and Polyamine Concentration in the Human Intestine: A Pilot Study
Tập 51 Số 1 - Trang 25-35 - 2007
AbstractThe fecal microbiota of 10 hospitalized elderly subjects and 14 healthy
adults were analyzed by terminal‐restriction fragment length polymorphism
(T‐RFLP) analysis using HhaI, MspI, HaeIII, and AluI, as well as fecal polyamine
(PA) concentration. The T‐RFLP profiles of the fecal microbiota of the subjects
were roughly divided into 2 clusters—I (9 out of 11 were derived from
hospitalized el...
Anti‐inflammatory properties of intestinal Bifidobacterium strains isolated from healthy infants
Tập 56 Số 1 - Trang 27-39 - 2012
ABSTRACTCertain 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 Bifidobacterium strains isolated from feces of healthy infants is reported.
