Microscopic 'clutch' puts flagellum in neutral
A tiny but powerful engine that propels the bacterium Bacillus subtilis through liquids is disengaged from the corkscrew-like flagellum by a protein clutch, Indiana University Bloomington and Harvard University scientists have learned. Their report appears in this week's Science. view more (2008-06-20)
Corrosion-inhibiting coatings containing 'good' bacteria
A new, environmentally friendly coating that protects metals against corrosion in seawater has been developed by a team of researchers from Sheffield Hallam University. view more (2009-03-30)
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)
Winemaking waste proves effective against disease-causing bacteria in early studies
A class of chemicals in red wine grapes may significantly reduce the ability of bacteria to cause cavities, according to a study published recently in the Journal of Agricultural and Food Chemistry. view more (2008-01-03)
Microbiology Online: Free resources for teachers
The Society for General Microbiology (SGM) has launched Microbiology Online - a new web site for biology teachers and technicians in schools and colleges. The site is packed with information and resources to support microbiology teaching at all key stages and post-16 level. view more (2002-02-19)
Bacteria 'launch a shield' to resist attack
Researchers from the University of Copenhagen and the Technical University of Denmark along with other collaborators in Denmark and the US found that the bacterium Pseudomonas aeruginosa can 'switch on' production of molecules that kill white blood cells - preventing the bacteria being eliminated by the body's immune system. view more (2009-11-02)
E. coli persists against antibiotics through HipA-induced dormancy
Bacteria hunker down and survive antibiotic attack when a protein flips a chemical switch that throws them into a dormant state until treatment abates, researchers at The University of Texas M. D. Anderson Cancer Center report in the Jan.16 edition of Science. view more (2009-01-16)
Princeton scientists break cholera's lines of communication
A team of Princeton scientists has discovered a key mechanism in how bacteria communicate with each other, a pivotal breakthrough that could lead to treatments for cholera and other bacterial diseases. view more (2007-11-15)
Should dentists worry about vCJD transmission?
Existing guidelines on treating patients with diseases such as Creutzfelt-Jakob disease (CJD) do not cover dental health in any detail. Writing in the April Journal of the Royal Society of Medicine, Professor Stephen Porter of the Eastman Dental Institute at the University of London suggests "important modifications" to the current infection... view more...

Plant Microbe Shares Features with Drug-Resistant Pathogen
An international team of scientists has discovered extensive similarities between a strain of bacteria commonly associated with plants and one increasingly linked to opportunistic infections in hospital patients. view more (2009-06-17)
New targets for combating infections in medical implants
Navarre researcher, Jaione Valle Turrillas, has identified two genes that could help as targets for pharmaceutical drugs that fight the Staphylococcus aureus "one of the bacteria which causes most infections in medical implants". The results of her research have been published in her PhD thesis, "The role of the global regulators SarA... view more... (2004-10-18)
Living sensor can warn of arsenic pollution
Scientists studying arsenic pollution have discovered a living sensor that can spot contamination. They have also discovered new bacteria that can clean up arsenic spills even in previously untreatable cold areas, microbiologists heard today (Monday 8 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at... view more...

Researchers Identify Biofilms That Cause Infection
Understanding the way bacterial cells "talk" to each other could lead to more effective methods for fighting the often persistent and serious infections caused by the biofilms they form, says a Texas A&M University professor of chemical engineering who not only has deciphered their language but also discovered how to quell their... view more...

Superbug genome sequenced
The genome of a newly-emerging superbug, commonly known as Steno, has just been sequenced. The results reveal an organism with a remarkable capacity for drug resistance. The research was carried out by scientists at the Wellcome Trust Sanger Institute near Cambridge and the University of Bristol. view more (2008-05-07)
UTSA biology researchers demystify elusive war zone bacterium
Tao Weitao, a researcher in the College of Sciences' Department of Biology at the University of Texas at San Antonio is making great strides in a project that was funded one year ago by the San Antonio Area Foundation. view more (2009-08-17)
