How 1 bacteria colonizes the gut and causes food poisoning

10-18-2007 · EurekAlert!

Food poisoning caused by the bacteria enterohemorrhagic Eschericia coli O157:H7A results in severe abdominal cramps and bloody diarrhea. In the very young and old it can also cause hemolytic uremic syndrome -- a disease characterized by anemia and kidney failure. A new study has provided new insight into the mechanisms by which EHEC colonize the intestines, which is essential if we are to develop strategies to prevent infection by this bacteria.

Fighting the spread of food poisoning
10-01-2007 · EurekAlert!
A Queensland University of Technology researcher has developed a new technique that can help scientists and clinicians quickly and cheaply diagnose the bacteria which causes the most common bout of food poisoning in Australia. Erin Price, from QUT's Faculty of Science, has developed a novel set of methods that uses genetic markers to pinpoint the bacteria Campylobacter jejuni.

Prehistoric origins of stomach ulcers uncovered
02-07-2007 · EurekAlert!
Scientists have discovered that the ubiquitous bacteria that causes most painful stomach ulcers has been present in the human digestive system since modern man migrated from Africa over 60,000 years ago. They compared DNA sequence patterns of humans and the Helicobacter pylori bacteria now known to cause most stomach ulcers and found that the genetic differences between human populations that arose as they dispersed from Eastern Africa over thousands of years are mirrored in H.pylori.

A friendly foe -- Bacteria residing in the gut boost immune response to tumors
07-26-2007 · EurekAlert!
Total body irradiation (TBI), which depletes the body of lymphocytes, improves the ability of tumor-specific T cells to cause tumor regression. In a new JCI study researchers show that, in mice, lymphodepletion does not fully account for the tumor regression observed following TBI. They show that disruption of the population of bacteria that normally reside in the gut without causing disease also plays a role in the effectiveness of this therapeutic approach against cancer.

Lettuce, leafy greens and E. coli
09-02-2007 · EurekAlert!
The rise in year-round consumption of fresh leafy greens such as lettuce and baby spinach is increasing the difficulty of keeping produce free from contamination by food poisoning bacteria, according to US scientists speaking today (Monday 3 Sept. 2007) at the Society for General Microbiology's 161st Meeting at the University of Edinburgh, UK, which runs from 3-6 Sept. 2007.

Humans not the major target of Shiga toxin
12-03-2007 · EurekAlert!
Food poisoning victims -- as a result, for example, of consuming Shiga-packing E.coli in a contaminated bag of spinach -- have always had the cold comfort of being told that not all common bacteria make humans extremely sick, only the strains that have integrated the Shiga gene into their DNA. These bacteria can produce large amounts of the Shiga toxin and release it into the surrounding environment.

Deprived bacteria grow up meaner
06-14-2007 · EurekAlert!
If the Listeria monocytogenes bacteria behind food poisoning are starved of oxygen, they are liable to turn really nasty according to research published today in the online journal BMC Microbiology. Limiting oxygen produces bacteria up to 100 times more invasive than similar bacteria grown with ample oxygen supplies.
