German researchers make significant strides in identifying cause of bacterial infections
Several bacterial pathogens use toxins to manipulate human host cells, ultimately disturbing cellular signal transduction. Until now, however, scientists have been able to track down only a few of the proteins that interact with bacterial toxins in infected human cells. view more (2009-04-23)
Novel bacterial strains clear algal toxins from drinking water
Novel bacterial strains capable of neutralizing toxins produced by blue-green algae have been identified by researchers at Robert Gordon's University, Aberdeen. view more (2009-09-08)
Toxic shock: immune system's anthrax link
Human immune proteins crucial for fighting cancer, viruses and bacterial infections belong to an ancient and lethal toxin family previously only found in bacteria, Australian researchers have found. view more (2007-08-24)
Vaccine could cut complications after surgery
A vaccine has been developed, which could prevent inflammation and illness caused by certain bacterial infections following major surgery, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick. Dr Elliott Bennett-Guerrero, Chief of Cardiac Anesthesia at Columbia... view more... (2002-04-03)
Detecting poisons in nectar is an odour-ous task for honeybees
Though many spring flowers have bright advertisements offering sweet rewards to honeybees, some common flowers have not-so-sweet or even toxic nectars. view more (2007-04-02)
Scientists Present 'Moving' Theory Behind Bacterial Decision-Making
Biochemists at North Carolina State University have answered a fundamental question of how important bacterial proteins make life-and-death decisions that allow them to function, a finding that could provide a new target for drugs to disrupt bacterial decision-making processes and related diseases. view more (2008-11-25)
Researchers discover how infectious bacteria can switch species
Scientists from the Universities of Bath and Exeter have developed a rapid new way of checking for toxic genes in disease-causing bacteria which infect insects and humans. view more (2008-10-09)
Prevention is better than cure
The Institute of Biology is calling on the International Community to strengthen the Biological and Toxins Weapons Convention. In a statement to be presented to the Fifth Review Conference of the Parties to the Biological and Toxins Weapons Convention (BTWC), the Institute warns that the current genomics revolution may be misused unless a... view more...

Bacteria for plague control in agriculture
Bacillus thuringiensis, a spore bacteria discovered in 1901 by the Japanese scientist Ishiwata and, ten years later, by the German scientist Berliner came across his findings. It is the micro-organism most used as a bio-insecticide throughout the world. It is a bacterium found naturally in ecosystems, frequently on floors and on the surface of... view more... (2003-02-14)
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)
New Collection Of Bacteria
In recent times, efforts in protecting plants from insect pests are aimed at reducing the use of chemical controls, i.e., pesticides, and employing biological methods. The latter, as distinct from the chemical ones, do not contaminate the environment and agricultural products, do not accumulate in soil and water, and do not poison warm-blooded... view more...

Molecular structure reveals how botulinum toxin attaches to nerve cells
Botulism is a life-threatening disease caused by exposure to botulinum neurotoxins, which are among the most potent toxins known. These neurotoxins are produced by Clostridium botulinum, a bacterium found in soil and food. view more (2006-12-14)
A new understanding of how cells defend themselves against bacterial pore-forming toxins
Biologists at the EPFL (Ecole Polytechnique Federale de Lausanne) have unveiled a new twist in a metabolic pathway that cells use to defend themselves against toxins made by disease-causing bacteria. view more (2006-09-22)
New designer toxins kill Bt-resistant insect pests
A new way to combat resistant pests stems from discovering how the widely used natural insecticide Bt kills insects. view more (2007-11-02)
Researchers discover RNA repair system in bacteria
In new papers appearing this month in Science and the Proceedings of the National Academy of Sciences, University of Illinois biochemistry professor Raven H. Huang and his colleagues describe the first RNA repair system to be discovered in bacteria. view more (2009-10-13)
Insect Resistance to Bt Crops can be Predicted, Monitored, and Managed
Since 1996, crop plants genetically modified to produce bacterial proteins that are toxic to certain insects, yet safe for people, have been planted on more than 200 million hectares worldwide. view more (2009-11-24)
Change policy: Giving steroids to children with meningitis can reduce hearing loss and lower the incidence of long-term brain damage and can save lives in both children and adults with meningitis
Research News in the Cochrane Database of Systematic Reviews Antibiotics are essential and life-saving in the treatment of bacterial meningitis, but for years doctors have debated whether to give corticosteroids at the same time. The inflammation caused by meningitis can actually be made worse by antibiotics in the short term, as the bacteria... view more... (2003-09-23)

NEW LOOK ENVIRONMENT AWARD FOR ENGINEERS LAUNCHED FOR 1999
The competition, the only award to recognise the achievements of individual engineers in their work to protect and enhance the environment, is reshaped for 1999 with a totally new class structure that mirrors current environmental concerns and Government initiatives. view more (1999-03-11)
Study Finds Anthrax Toxins Also Harmful To Fruit Flies
Deadly and damaging toxins that allow anthrax to cause disease and death in mammals have similar toxic effects in fruit flies, according to a study conducted by biologists at the University of California, San Diego. view more (2006-01-31)
