New biosensor can detect bacteria instantaneously
A research group from the Rovira i Virgili University (URV) in Tarragona has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. view more (2009-09-09)
New research sheds light on bacterial firework display
Scientists at the Institute for Animal Health have revealed how a tropical bacterium is able invade cells, and ultimately trigger its escape using a homemade rocket. Their work is published in the November issue of Molecular Microbiology. A group of scientists led by Dr Ed Galyov and Dr Mark Stevens have discovered that Burkholderia pseudomallei,... view more...

Casting out devils
In the scientific journal PLoS ONE, Sara Bartels and Siegfried Weiss of the Helmholtz Centre for Infection Research (HZI) in Braunschweig, Germany now show how the bacteria migrate into tumours. view more (2009-09-09)
UCSB researchers develop cross-protective vaccine
Doctors have always hoped that scientists might one day create a vaccination that would treat a broad spectrum of maladies. They could only imagine that there might be one vaccine that would protect against, say, 2,500 strains of Salmonella. view more (2008-10-22)
New study shows health benefits of probiotic could extend to the entire body
Data from a recent study demonstrate the anti-inflammatory and pathogen protection benefits of Bifidobacterium infantis 35624 a probiotic bacterial strain of human origin. view more (2008-08-25)
The world`s most stable genome has been identified in aphid endosymbionts
Bacteria that reproduce inside aphids have not changed their genetic make-up for the last 50-70 million years. This makes the genomes of these bacteria the most stable of all organisms yet studied. This finding is presented by a team of scientists at Uppsala University, Sweden, in the latest issue of the scientific journal Science. Under the... view more... (2002-06-28)
Researchers uncover E. coli's defense mechanism
The pathogenic forms of E. coli and Salmonella are usually transmitted to humans through undercooked meat, unwashed vegetables and cross contamination from surfaces on which these foods were prepared. view more (2005-09-29)
From foe to friend: Researchers use salmonella as a way to administer vaccines in the body
Researchers at the Biodesign Institute at Arizona State University have made a major step forward in their work to develop a biologically engineered organism that can effectively deliver an antigen in the body. The researchers report that they have been able to use live salmonella bacterium as the containment/delivery method for an antigen. view more (2008-07-09)
Fresh produce - Potential Risk for Consumers
Vegetables are good examples of minimally processed foods with high risk of contamination and therefore good hygienic measures have to be taken during the production from farm to table. The nature and extent of the health hazards involved in the production and preparation of foods will be considered in depth at the FEMS Congress of European... view more... (2003-05-29)
Understanding, combating foodborne pathogens E. coli 0157 and salmonella
Understanding the ecology of two dangerous foodborne pathogens and devising ways to combat them is a big job. That's why Kansas State University has a team of seven researchers and six collaborators taking on E. coli 0157 and salmonella. view more (2007-10-17)
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)
Breaks in hibernation help fight bugs
A habit in some animals to periodically wake up while hibernating may be an evolutionary mechanism to fight bacterial infection, according to researchers at Penn State. view more (2006-08-17)
Biofilm of Salmonella
Advances in the study of the salmonella bacteria, being undertaken at the Pamplona Institute of Agrobiotechnology and Natural Resources and led by professor I'ħigo Lasa Uzcudun of the Public University of Navarre, have been recognised in the principal international magazine in the field of Microbiology, Molecular Microbiology, at a congress held... view more...

ETH Zurich study on salmonella self-destruction
ETH Zurich biologists, led by Professors Martin Ackermann and Wolf-Dietrich Hardt, in collaboration with Michael Doebeli of the University of British Colombia in Vancouver (CN), have been able to describe how random molecular processes during cell division allow some cells to engage in a self-destructive act to generate a greater common good,... view more...

Even before tomato warning, many Americans lacked confidence in the food safety system
A new national study conducted by the Harvard School of Public Health Project on the Public and Biological Security finds that, in spite of a number of food safety incidents in recent years, most Americans remain confident that the food produced in the United States is safe. However, many have concerns about the safety of imported food produced in... view more... (2008-06-13)
Microscopic 'astronauts' to go back in orbit
When space shuttle Endeavor blasts off on March 11, some tiny 'astronauts' will piggyback onboard an experimental payload from Arizona State University's Biodesign Institute. view more (2008-03-11)
Will the plague pathogen become resistant to antibiotics?
A small piece of DNA that helps bacteria commonly found in US meat and poultry resist several antibiotics has also been found in the plague bacillus Yersinia pestis, gene sequence researchers report. view more (2007-03-21)
From poison to prevention
One of the major challenges in modern vaccinology is to engineer vectors that are highly infectious, yet don't cause illness. Trickier still is to ensure that such weapons against infectious disease can be safely disarmed, once their immunogenic work is done. view more (2009-01-13)
U of Minnesota study finds confidence in food safety plunges in wake of peanut butter contamination
Fewer than one in four consumers now believe the U.S. food supply is safer than it was a year ago, according to new data from the University of Minnesota's Food Industry Center. view more (2009-02-25)
An infectious agent of deception, exposed through proteomics
Salmonella bacteria, infamous for food poisoning that kills hundreds of thousands worldwide, infect by stealth. view more (2006-09-29)
