An efficient approach to monitor gastrointestinal microflora changes
Pi-deficiency in traditional Chinese medicine (TCM) is one of the most common digestive diseases and usually the equilibrium of gastrointestinal microflora are broken, which plays many important roles in the growth, development and performance of the host. view more (2009-05-22)
Foodborne infections in the home linked to social functions
Although there has been a downward trend in outbreaks of infectious intestinal diseases in the home, food is the predominant transmitter of infection, and seems to be linked to social functions such as barbecues and dinner parties, finds a study in this week's BMJ. view more (2001-11-07)
When intestinal bacteria go surfing
The bacterium Escherichia coli is part of the healthy human intestinal flora. However, E. coli also has pathogenic relatives that trigger diarrhea illnesses: enterohemorrhagic E.coli bacteria. During the course of an infection they infest the intestinal mucosa, causing injury in the process, in contrast to benign bacteria. view more (2009-03-19)
Curbing C. difficile's toxin production
As if being admitted to the hospital weren't bad enough, patients, once admitted, are at higher risk of becoming infected with a "superbug" bacterium, Clostridium difficile (C. difficile). view more (2007-09-06)
Il-22 gene delivers the goods and decreases intestinal inflammation
There are two major types of inflammatory bowel disease (IBD), Crohn disease (CD) and ulcerative colitis (UC). view more (2008-01-03)
Advance in cholera bacteria points to new treatment and vaccine
Opening a new door to an effective vaccine and therapy for a disease that strikes thousands annually, researchers at Dartmouth Medical School discovered that the bacteria that causes the intestinal disease Cholera spreads in the environment in much the same way it infects humans. view more (2005-12-08)
Probiotics ease gut problems caused by long term stress
Probiotics may help to reduce gut symptoms caused by long term stress, indicates research published ahead of print in the journal Gut. view more (2006-04-25)
New lights on the pathogenic mechanisms of liver cirrhosis with ascites
The pathogenic mechanisms implicated in the failure of intestinal barrier in cirrhosis have not been fully elucidated as yet and remains to be investigated. view more (2008-09-24)
Transgenic goat's milk offers hope for tackling children's intestinal disease
It's hard to improve on milk, but animal scientists at the University of California, Davis, have found that milk produced by transgenic goats, which carry the gene for an antibacterial enzyme found in human breast milk, altered the intestinal bacteria in young goats and pigs that were fed the milk. view more (2006-08-07)
Bacteria with a built-in thermometer
Researchers in the "Molecular Infection Biology group" at the Helmholtz Centre for Infection Research (HZI) in Braunschweig and the Braunschweig Technical University could now demonstrate for the first time that bacteria of the Yersinia genus possess a unique protein thermometer - the protein RovA - which assists them in the infection... view more...

A low-cholesterol diet leaves a bitter taste in the gut
One role for the proteins on the tongue that sense bitter tasting substances, type 2 taste receptors (T2Rs), is to limit ingestion of these substances, as a large number of natural bitter compounds are known to be toxic. view more (2008-10-10)
Sesame seed extract and konjac gum may help ward off Salmonella and E. coli
A new study in SCI's Journal of the Science of Food and Agriculture shows that konjac gum and sesame seed extract may offer protection against different strains of E. coli and Salmonella bacteria. view more (2008-08-06)
Why doesn't the immune system attack the small intestine?
Answering one of the oldest questions in human physiology, researchers at Dana-Farber Cancer Institute have discovered why the body's immune system-perpetually on guard against foreign microbes like bacteria - doesn't attack tissues in the small intestine that harbor millions of bacteria cells. view more (2007-01-10)
Vitamin A deficiency linked to major intestinal surgery
Major intestinal surgery, including stomach reduction for obesity, may boost the chances of subsequent vitamin A deficiency, suggests a small study published ahead of print in the British Journal of Ophthalmology. view more (2006-06-14)
How 1 bacteria colonizes the gut and causes food poisoning
Food poisoning caused by the bacteria enterohemorrhagic Eschericia coli (EHEC) O157:H7A results in severe abdominal cramps and bloody diarrhea. view more (2007-10-19)
Is the intestinal mucosa barrier malfunction involved in non-alcoholic steatohepatitis?
The pathogenesis of NASH remains unclear. Nowadays, lipid metabolism abnormality, insulin resistance and oxidative stress and lipid peroxidation reaction are thought to place an important role in the pathogenesis of NASH. view more (2008-09-18)
Gut check: Tracking the ecosystem within us
For more than 100 years, scientists have known that humans carry a rich ecosystem within their intestines. An astonishing number and variety of microbes, including as many as 400 species of bacteria, help humans digest food, mitigate disease, regulate fat storage, and even promote the formation of blood vessels. view more (2007-06-26)
Tufted bacteria cause infection in premature babies
Bacteria that normally reside on the skin of healthy people can cause serious infections in premature babies. A group of researchers at Karolinska Institutet have now found an explanation for why a certain kind of staphylococcus can attach itself to the skin and quickly develop dynamic ecosystems: the bacteria are like tufted, self-adhesive... view more...

Stressed intestine can give rise to food allergy
The intestines of mice which have been subjected to stress, overreact to certain nutritional substances. PhD biologist Annette van Kalkeren from the University of Amsterdam has investigated the relationship between stress and the occurrence of food allergies and various intestinal disorders. The biologist investigated the reaction of pieces of... view more... (2002-04-18)
DNA of good bacteria drives intestinal response to infection
A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection. view more (2008-10-03)
