No Benefits From Vitamin Supplements In Protection Against Gastro-Intestinal Cancer (pp 1193, 1219)
A systematic review and meta-analysis (pooled analysis) of previously published randomised trials in this week's issue of THE LANCET provides strong evidence that antioxidant supplements (such as vitamin supplements) are not effective in protecting against gastro-intestinal cancer. Some combinations of supplements may slightly increase... view more... (2004-09-29)
Gene exchange common among sex-manipulating bacteria
Certain bacteria have learned to manipulate the proportion of females and males in insect populations. Now Uppsala University researchers have mapped the entire genome of a bacterium that infects a close relative of the fruit fly. view more (2009-03-26)
UB Scientist Discovers Novel Iron-Copper Alliance
Iron is the workhorse of trace minerals. An essential component of red blood cells, disruption of iron levels in the body will result in a myriad of serious conditions, and life cannot be sustained without it. view more (2007-07-24)
Scientists seek to unwrap the sweet mystery of the sugar coat on bacteria
Scientists at The University of Texas at Austin have developed a quick and simple way to investigate the sugar coating that surrounds bacteria and plays a role in infection and immunity. view more (2006-02-15)
US adults now discovering the secrets of probiotics
Probiotic supplements have been used around the world for at least half a century, but almost half (49 percent) of Americans indicate that they have never heard of them, according to a recent survey conducted by Harris Interactive® for Florastor®, the world's top-selling probiotic, now being launched widely in the United States. view more (2007-03-13)
The biggest bug in gut discomfort
In spite of our long and painful relationship with Campylobacter jejuni, we are just starting to answer basic questions about the bug that is the leading cause of bacterial food-borne illness in the United States, and one of the most common causes of diarrhea worldwide. view more (2006-12-13)
Waterproof superglue may be strongest in nature
The glue one species of water-loving bacteria uses to grip its surroundings may be the strongest natural adhesive known to science. view more (2006-04-12)
At petting zoos, simple disease prevention guidelines frequently ignored
A new study shows that simple guidelines to protect petting zoo patrons from disease-causing germs found in the zoo are frequently not followed, thus allowing the risks of contracting serious intestinal illnesses to persist. view more (2007-06-12)
Natural gas inhabited by unusual specialists
A German-American research team of biologists and geochemists has discovered hitherto unknown anaerobic bacteria in marine sediments which need only propane or butane for growth. view more (2007-09-24)
New study shows that bacteria can communicate through the air
This month, Journal of Applied Microbiology publishes a ground-breaking study demonstrating that bacteria which are physically separated can transmit information through the air. It is well documented that bacteria can exchange messages by releasing substances into a surrounding liquid culture medium, but this new study is the first to demonstrate... view more... (2002-05-27)
Antibiotics-resistant gulls worry scientists
The resistance pattern for antibiotics in gulls is the same as in humans, and a new study by Uppsala University researchers shows that nearly half of Mediterranean gulls in southern France have some form of resistance to antibiotics. view more (2009-06-18)
Getting better with a little help from our 'micro' friends
A naturally occurring molecule made by symbiotic gut bacteria may offer a new type of treatment for inflammatory bowel disease, according to scientists at the California Institute of Technology. view more (2008-05-29)
Is transforming growth factor-beta involved in intestinal wound healing?
Migration of colonic lamina propria fibroblasts (CLPF) plays an important role during the progression of fibrosis and fistulae in Crohn's disease. Transforming growth factor- beta (TGF- beta) is involved in the regulation of cell migration, cell differentiation, extracellular matrix deposition, and immune responses. view more (2009-03-31)
Protein discovery could unlock the secret to better TB treatment
UCL scientists have found a protein that could unlock the secret to quicker, more effective treatment of TB by waking TB bacteria in the body. Once the TB bacteria are active again, the disease becomes treatable using common drugs like antibiotics. Scientists believe that uncovering the molecular structure of this protein will lead the way to... view more... (2005-02-28)
New antibiotic prescribing policies needed to curb resistance BMJ Volume 324, pp 28-30
Effect of B lactam antibiotic use in children on pneumococcal resistance to penicillin: prospective cohort study The likelihood of children carrying a resistant bug is related to the amount of antibiotics they take, finds a study in this week's BMJ. If these drugs are to retain their clinical usefulness, new prescribing policies are needed, argue... view more... (2002-01-02)
Algae understand the language of bacteria
It has hitherto not been known that higher organisms, such as green algae, can communicate with bacteria. But Debra Milton, associate professor at Ume'å University in Sweden, shows in the recent issue of the prominent journal Science that bacteria attract green algae with the aid of signal molecules. Surfaces under water are rapidly... view more... (2002-11-12)
Probiotic bacteria at weaning may help alleviate allergy in infants
“Friendly” bacteria (probiotics) given to babies during weaning may help alleviate the symptoms of eczema, suggests research in Gut. view more (2002-06-20)
Gas-guzzling bacteria
The discovery of a new soil bacterium that consumes methane by oxidising it under atmospheric conditions is reported in Nature, out today. In well-drained soils, these methane-oxidising bacteria can reduce atmospheric levels of methane by 10 per cent. Methane is an important greenhouse gas, and over the last 200 years its concentration in the... view more... (2000-05-10)
Probiotic Found to Be Effective Treatment for Colitis In Mice
The probiotic, Bacillus polyfermenticus, can help mice recover from colitis, a new study has found. view more (2009-10-26)
How to make sure that beneficial probiotic bacteria reach consumers in an active way?
Yoghurt is often used as a carrier product for beneficial probiotic bacteria. Yoghurt, as such, has a positive health image among consumers and is part of everyday diet in most European countries. However, making yoghurt a truly probiotic product is a challenging task. Firstly, the probiotic bacteria have to be viable in the product, so that the... view more... (2003-01-17)
