Structure of antibiotic ramoplanin reveals promising mechanism
With the "last resort" antibiotic Vancomycin now plagued by the first signs of bacterial resistance, a scientific collaboration centered at Duke University has identified how a candidate successor antibiotic known as Ramoplanin A2 can kill pathogenic bacteria by interrupting how they form their cell membranes. view more (2009-08-04)
Genes key to staph disease severity, drug resistance found hitchhiking together
Scientists studying Staphylococcus bacteria, including methicillin-resistant S. aureus (MRSA), have discovered a potent staph toxin responsible for disease severity. view more (2009-08-03)
NYU Langone Medical Center researchers find altered micriobiome prevalent in the diseased esophagus
Gastroesophageal reflux diseases , or GERD, affects about 10 million people in the United States, yet the cause and an unexpected increase in its prevalence over the last three decades remains unexplainable. view more (2009-08-03)
Bacteria pack their own demise
Numerous pathogens contain an 'internal time bomb', a deadly mechanism that can be used against them. After years of work, VIB researchers at the Vrije Universiteit Brussel (VUB) were able to determine the structure and operating mechanism of the proteins involved. view more (2009-07-31)
Microbes and their hosts -- exploring the complexity of symbiosis in DNA and cell biology
The unique association between microorganisms and their hosts, whether insects, plants, or mammals, provides a fascinating view into how microbial symbionts adapt to changing biological environments. view more (2009-07-29)
Test helps in fight against lung infections and for treating other life-threatening infections
A new test developed by Edmonton-based Innovotech™ Inc. will now allow doctors to more accurately identify the right antibiotics required to treat serious, chronic infections that are biofilm based. view more (2009-07-29)
Researchers capture bacterial infection on film
Whilst most studies of bacterial infection are done after the death of the infected organism, this system developed by scientists at the University of Bath and University of Exeter is the first to follow the progress of infection in real-time with living organisms. view more (2009-07-28)
Stress signals link pre-existing sickness with susceptibility to bacterial infection
Mitochondrial diseases disrupt the power generating machinery within cells and increase a person's susceptibility to bacterial infection, particularly in the lungs or respiratory tract. view more (2009-07-28)
Pinpointing cause of colic: UT Houston research identifies organism that could trigger constant crying
Researchers at The University of Texas Health Science Center at Houston say one organism discovered during their study may unlock the key to what causes colic, inconsolable crying in an otherwise healthy baby. view more (2009-07-27)

US researchers have created 'bacterial computers' with the potential to solve complicated mathematics problems. view more (2009-07-24)
New silver nanoparticle skin gel for healing burns
Scientists in India are reporting successful laboratory tests of a new and potentially safer alternative to silver-based gels applied to the skin of burn patients to treat infections. With names like silver sulfadiazine and silver nitrate, these germ-fighters save lives and speed healing. view more (2009-07-23)
Study aims to induce recovery from ankylosing spondylitis
Chinese patients will soon have the opportunity to take part in a study of a novel therapy aimed at reversing the autoimmune disease, ankylosing spondylitis. view more (2009-07-22)
Cystic fibrosis treatments may have unseen long-term benefits
Cystic fibrosis medicines that help to break down mucus in the lungs may carry an unexpected long-term benefit, a study suggests. view more (2009-07-17)
Probiotics help gastric-bypass patients lose weight more quickly, Stanford study shows
New research from the Stanford University School of Medicine and Stanford Hospital & Clinics suggests that the use of a dietary supplement after Roux-en-Y gastric bypass surgery can help obese patients to more quickly lose weight and to avoid deficiency of a critical B vitamin. view more (2009-07-14)
Data published in the New England Journal of Medicine support use of raxibacumab (ABthrax) for the treatment of inhalation anthrax
Human Genome Sciences, Inc. (Nasdaq: HGSI) today announced publication by the New England Journal of Medicine of the results of two pivotal animal efficacy studies, which showed the life-saving potential of the Company's human monoclonal antibody drug raxibacumab. view more (2009-07-10)
Toward an explanation for Crohn's disease?
Twenty-five per cent of Crohn's disease patients have a mutation in what is called the NOD2 gene, but it is not precisely known how this mutation influences the disease. view more (2009-07-10)
Forsyth scientists suggest linkages between obesity and oral bacterial infection
A scientific team from The Forsyth Institute has discovered new links between certain oral bacteria and obesity. view more (2009-07-09)
Is obesity an oral bacterial disease?
The world-wide explosion of overweight people has been called an epidemic. The inflammatory nature of obesity is widely recognized. view more (2009-07-09)
Scientists track chemical changes in cells as they endure extreme conditions
One of nature's most gripping feats of survival is now better understood. For the first time, scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory observed the chemical changes in individual cells that enable them to survive conditions that should kill them. view more (2009-07-08)
