New miniaturised chip dramatically reduces time taken for DNA analysis
A team of researchers at the Universitat Autònoma de Barcelona has developed new miniature sensors for analysing DNA. The sensors have the same size and thickness as a fingernail and reduce the time needed to identify DNA chains to several minutes or a few hours, depending on each chain. These sensors can be applied to many different tasks,... view more... (2005-04-04)
Microbial website has a makeover
Microbes are everywhere and affect every aspect of our lives. Who hasn’t heard of SARS, HIV, E. coli O157 or Salmonella? The world needs microbiologists to keep one step ahead of the bugs, and there has to be a way of passing on vital information about microbiological issues. The Society for General Microbiology (SGM) aims to promote the... view more... (2003-06-06)
Fish slime crock of gold at end of rainbow
The slippery mucus on the skin of rainbow trout is being studied by scientists as a possible source of new medicines to fight infectious diseases, according to research presented today (Monday, 06 September 2004) at the Society for General Microbiology's 155th Meeting at Trinity College Dublin. view more (2004-08-23)
What are the predominant bacilli in the intestines ducklings infected with S. enteritidis?
The enterobacterial repetitive intergenic consensus-PCR (ERIC-PCR) method has been used to fingerprint the kinetics of microbial community of fecal samples of ducklings orally infected with S. enteritidis. view more (2008-03-13)
TraDIS technique tackles typhoid
For the first time, researchers are able to look at the need for every gene in a bacterial cell in a single experiment. The new method will transform the study of gene activity and the search for weaknesses in bacterial armouries. view more (2009-10-16)
Climate change may affect length of respiratory infection season
Rising global temperatures over the past two decades may be responsible for a shortened season of a serious respiratory illness in the United Kingdom. view more (2006-02-10)
Unpasteurized milk poses health risks without benefits
With disease outbreaks linked to unpasteurized milk rising in the United States, a review published in the January 1, 2009 issue of Clinical Infectious Diseases examines the dangers of drinking raw milk. view more (2008-12-17)
What is the function of NOD2 in colonic epithelial cells?
NOD2 is a cytosolic pattern recognition receptor similar in structure and function to Toll like receptors (TLRs). It can recognize and respond to a component found in the cell wall of bacteria, muramyl dipeptide (MDP), and has been shown to play an important role in the innate immune response of macrophages to bacterial infections. view more (2008-10-23)
Cornell scientists link E. coli bacteria to Crohn's disease
A team of Cornell University scientists from the College of Veterinary Medicine, Weill Cornell Medical College and the College of Agriculture and Life Sciences have discovered that a novel group of E. coli bacteria - containing genes similar to those described in uropathogenic and avian pathogenic E. coli and enteropathogenic bacteria such as... view more...

Enzyme necessary for DNA synthesis can also erase DNA
In this week's edition of Proceedings of the National Academy of Sciences, PNAS, Uppsala University scientists describe a new mechanism behind an important process that causes a rapid reduction of DNA in the chromosomes of bacteria. view more (2009-06-09)
Reduced Risk from Appendix, Bowel or Birth
The risk of life threatening infection after a burst appendix, childbirth or bowel surgery has just been reduced, according to medical researchers who have discovered how a particularly dangerous bacterium fools our body's defences. The findings are presented today, Tuesday 8 April 2003, by Dr Sheila Patrick at the Society for General... view more... (2003-04-02)
If you don't want to fall ill this Christmas, then share a festive kiss but don't shake hands
We've all heard people say 'I won't kiss you, I've got a cold'. But a report just published warns that we may be far more at risk of passing on an infection by shaking someone's hand than in sharing a kiss. view more (2007-12-20)
Exploring the final frontier: Disease proposed as major barrier to Mars and beyond
New research published in the Journal of Leukocyte Biology suggests that prolific virulence and growth of bacteria, coupled with reduced production of antibodies could limit future space travel. view more (2009-10-30)
Food could be made safer by surface decontamination with steam
Trials have been carried out using steam below, at, or above atmospheric pressure. As the pressure of the steam is increased, higher decontamination temperatures can be achieved. Comparative studies are also assessing the use of treatments with hot air, water immersion, infrared irradiation, ultraviolet (UV) light, microwaves, or ozone. view more (1999-11-29)
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)
Cases of serious food poisoning rise in real terms, although overall rates down
Cases of serious food poisoning in England and Wales requiring admission to hospital have risen in real terms over the past decade, shows research in Gut. This is despite rates of overall illness having halved over the same time period. The UK governmental Food Standards Agency has set a target of cutting the rates of foodborne illness by 20 per... view more... (2002-11-12)
Life Cycle of Operons Yields New Look at Bacterial Genetics
In a breakthrough that will immediately benefit biologists who study bacteria, and could in the future have bearing on the advancement of synthetic biology, a team of researchers has determined the life cycle of operons, small groups of genes with related functions that are co-transcribed in a single strand of messenger RNA. view more (2006-07-06)
Typhoid fever led to the fall of Athens
Scientists have for many years debated the cause of the Plague of Athens. Analysis carried out by Manolis Papagrigorakis and colleagues using DNA collected from teeth from an ancient Greek burial pit points to typhoid fever as the disease responsible for this devastating epidemic. view more (2006-01-24)
Novel plague virulence factor identified
Researchers at Duke University Medical Center have identified a previously unknown family of virulence factors that make the bacterium responsible for the plague especially efficient at killing its host. view more (2005-08-29)
Baiting bacteria with polymers
Anyone who has experienced food poisoning while on vacation in warm climates is sure to recognize the importance of safeguarding hygiene - and of microbial food testing. Since many types of bacteria, such as salmonella, multiply at an exceptionally fast rate in warm weather on meat or in milk products, relatively lengthy laboratory investigations... view more...
