Investigators at Burnham Institute for Medical Research (Burnham), University of California, San Diego, The Scripps Research Institute (TSRI), Genomics Institute of the Novartis Research Foundation (GNF) and other institutions have constructed a complete model, including three dimensional protein structures, of the central metabolic network of the bacterium Thermotoga maritima (T. maritima).

Researchers uncover secrets of ulcer-causing bacteria

A team of researchers from Boston University, Harvard Medical School and Massachusetts Institute of Technology recently made a discovery that changes a long held paradigm about how bacteria move through soft gels. They showed that the bacterium that causes human stomach ulcers uses a clever biochemical strategy to alter the physical properties of its environment, allowing it to move and survive and further colonize its host.

How Bacteria Measure Temperature

Researchers in the "Molecular Infection Biology group" at the Helmholtz Centre for Infection Research (HZI) in Braunschweig and the Braunschweig Technical University could now demonstrate for the first time that bacteria of the Yersinia genus possess a unique protein thermometer – the protein RovA - which assists them in the infection process.

Scientists in Indiana are reporting development of a new biosensor for use in a faster, more sensitive test for detecting the deadliest strain of Listeria food poisoning bacteria.

ISU researchers develop technique for quick detection of Salmonella

In the hours following an outbreak of salmonella, there are many questions. And answers can be hard to find.

Friendly bacteria reduce hospital infections

A probiotic bacterium, Lactobacillus plantarum 299, has been used to out-compete the dangerous bacteria that cause respiratory illness in ventilated patients.

Persistent bacterial infection exploits killing machinery of immune cells

A new study reveals an important and newly discovered pathway used by disease-causing bacteria to evade the host immune system and survive and grow within the very cells meant to destroy them. This discovery may lead to new treatments and vaccines for tuberculosis (TB) and certain other chronic bacterial and parasitic infections.

Commercial product effectively kills bacteria in vegetable washwater

Research conducted by food science faculty at the University of Idaho and Washington State University indicate that a commercially available fruit and vegetable wash, when used in a food-manufacturing setting, can dramatically decrease the number of disease-causing organisms in produce-processing washwater.

Scientist study bacterial communities inside us

The number of bacteria living within the body of the average healthy adult human are estimated to outnumber human cells 10 to 1. Changes in these microbial communities may be responsible for digestive disorders, skin diseases, gum disease and even obesity.

Breakthrough in plant research

The research groups of the Department of Biological and Environmental Sciences of the University of Helsinki and the University of California in San Diego have discovered a gene that is centrally involved in the regulation of carbon dioxide uptake for photosynthesis and water evaporation in plants.

Silica smart bombs deliver knock-out to bacteria

Bacteria mutate for a living, evading antibiotic drugs while killing tens of thousands of people in the United States each year. But as concern about drug-resistant bacteria grows, one novel approach under way at the University of North Carolina at Chapel Hill seeks to thwart the bug without a drug by taking a cue from nature.

Bacteria and nanofilters — the future of clean water technology
