What can we do for prevention and therapy of anaerobe-associated infections?
September 26, 2008Anaerobic microorganisms are important constituents of both human and animal intestinal microbiota. Infections caused by anaerobic bacteria are increasingly being recognized as major problem in clinical medicine. The commensal anaerobic bacterial flora of the colon may undergo changes during diarrhea, owing to colonization of the intestine by pathogens and to rapid intestinal transit. The major role of endogenous cationic antimicrobial peptides in preventing the onset of infection has been emphasized recently. Such peptides have been found platelets and are designated PMP. Here a group from Institute of Cellular and Intracellular Symbiosis of Russia made an attempt to in vitro detection of SIPMP phenotypes of faecal anaerobic isolates from patients with diarrhea.
A research article to be published on September 21,2008 in the World Journal of Gastroenterology addresses this question. The research team led by Dr. Iuri B. Ivanov from Institute of Cellular and Intracellular Symbiosis of Russia studied SIPMP phenotypes of faecal anaerobic isolates from patients with diarrhea.
The article focuses on inhibition of PMP by extracellular bacterial products of faecal anaerobic microorganisms isolated from stool of children with diarrhea. Among anaerobic isolates 80% of B. longum strains, 85.7% of A. israelii strains, 50% of E. lentum strains and 92.86% of B. fragilis strains were SIPMP-positive. The isolated anaerobic organisms demonstrated SIPMP production at a mean level of 13.8% ± 0.7%, 14.7% ± 1.8%, 3.9% ± 0.9% (P < 0.05) and 26.8% ± 7.5% (P < 0.05) for bifidobacteria, A. israelii, E. lentum and B. fragilis, respectively.
Data from the present study may have significant implications in understanding the pathogenesis of microecological disorders in intestine, as well as for future improvement in the prevention and therapy of anaerobe-associated infections.
In this manuscript, the authors reported the detection of secretory inhibitor of platelet microbicidal protein (SIPMP) phenotypes of faecal anaerobic isolates from patients with diarrhea. The study was well performed and interesting.

Anaerobic Current Events and Anaerobic News RSSCaltech researchers reveal unexpected sources of nitrogen fixation
Researchers at the California Institute of Technology (Caltech) have identified an unexpected metabolic ability within a symbiotic community of microorganisms that may help solve a lingering mystery about the world's nitrogen-cycling budget.
Gut Ecology in Transplant Patients
Small-bowel transplant patients with an ileostomy -- an opening into their small bowel -- have a very different population of bacteria living in their gut than patients whose ileostomy has been closed, researchers from UC Davis and Georgetown University Medical Center have found.
Denitrification, its importance once diluted, may be back on top, Princeton-led team says
After more than a decade of inquiry, a Princeton-led team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans.
Taking dex can improve high altitude exercise capacity in certain climbers
Taking dexamathasone prophlyactically may improve exercise capacity in some mountaineers, according to Swiss researchers. Dexamathasone, known popularly to climbers as "dex," has been used for years to treat altitude-related symptoms in mountaineers, but has never been tested for its ability to improve exercise capacity at high altitude.
Methane-eating microbes can use iron and manganese oxides to 'breathe'
Iron and manganese compounds, in addition to sulfate, may play an important role in converting methane to carbon dioxide and eventually carbonates in the Earth's oceans, according to a team of researchers looking at anaerobic sediments.
Scientists sequence genome of the N2-fixing, soil-living bacterium Azotobacter vinelandii
A collaboration of researchers, which includes scientists at the Virginia Bioinformatics Institute (VBI) and Virginia Tech, have completed the genome sequence of Azotobacter vinelandii, uncovering important genetic information that will contribute to a more complete understanding of the biology of this versatile, soil-living bacterium.
Impact of Floods on Soils
A recent study conducted in the Midwestern United States examined the effects of harsh wet conditions on both cultivated and uncultivated soils, vastly advancing the knowledge of water's effects on aggregation.

The Interval Training Workout: Build Muscle and Burn Fat with Anaerobic Exercise by M.D. Joseph T. Nitti (Author), Kimberlie Nitti (Author), Carl Lewis (Foreword) The Interval Training Workout, cowritten by a doctor and a certified trainer, shows how interval training can be done practically anywhere and benefit anyone who wants to get healthy. The training has three key components:·Interval training workoutswith brief repetitions of intense exercise alternating with intervals of rest; (extended) workouts: longer weekly sessions which allow certain biochemical and muscular adaptations that improve fitness and burn fat; and·active rest days: steady, comfortably paced exercises that help the body rest and recover while still burning calories. The book also offers specific customizable programs for training and tips for assessing performance and tracking progress. |
