Diptheria-tetanus-pertussis vaccine: an interview with Dr. Rudi Eggers, World Health Organisation

The Diptheria-tetanus-pertussis vaccine is sometimes also called the “triple vaccine” and has been around for about 50 years, and it protects against diphtheria, tetanus, and pertussis. These are serious diseases caused by bacteria.

California researchers develop new strategy to find novel antibiotics for bacterial infections

Researchers at the University of California, Santa Cruz, have developed a new strategy for finding novel antibiotic compounds, using a diagnostic panel of bacterial strains for screening chemical extracts from natural sources.

Chronic suppurative lung disease: an interview with Dr Robyn Marsh

Chronic suppurative lung disease, or CSLD, is used to describe a range of lung diseases characterised by a chronic wet cough and progressive lung damage. We are interested in the non-cystic fibrosis forms of the disease with a focus on bronchiectasis – the severe form of CSLD.

First evidence of blood vessel dysfunction found in healthy young people with cystic fibrosis

The first evidence of blood vessel dysfunction has been found in a small cohort of generally healthy young people with cystic fibrosis, researchers report.

Avermectin family of drugs shows promise against TB

A well-established family of drugs used to treat parasitic diseases is showing surprising potential as a therapy for tuberculosis (TB), according to new research from University of British Columbia microbiologists.

People worried about catching infections in public transport during flu season

As flu season gets underway, public transport such as buses, trains and subway trains head the list of places where people worry about catching viruses and infections, according to new research by Microban.

Microbiologists discover how the spread of antibiotic resistance works in pneumococcus

Antibiotic resistance results from bacteria's uncanny ability to morph and adapt, outwitting pharmaceuticals that are supposed to kill them. But exactly how the bacteria acquire and spread that resistance inside individuals carrying them is not well-established for most bacterial organisms.

Human Food Project, University of Colorado Boulder launch American Gut

Ever wondered who is living in your gut, and what they're doing? The trillions of microbial partners in and on our bodies outnumber our own cells by as many as 10 to 1 and do all sorts of important jobs, from helping digest the food we eat this Thanksgiving to building up our immune systems.

Synthetic membrane channels can be constructed through DNA nanotechnology

As reported in the journal Science, physicists at the Technische Universitaet Muenchen (TUM) and the University of Michigan have shown that synthetic membrane channels can be constructed through "DNA nanotechnology."

Hsp104 protein switches mechanism to break up amyloid versus disordered clumps

Several fatal brain disorders, including Parkinson's disease, are connected by the misfolding of specific proteins into disordered clumps and stable, insoluble fibrils called amyloid. Amyloid fibrils are hard to break up due to their stable, ordered structure. For example, α-synuclein forms amyloid fibrils that accumulate in Lewy Bodies in Parkinson's disease. By contrast, protein clumps that accumulate in response to environmental stress, such as heat shock, possess a less stable, disordered architecture.

UBC microbiologist receives Prix Galien 2012 Research Award

UBC microbiologist Robert E.W. Hancock has received the Prix Galien 2012 Research Award, widely considered the most prestigious honour in Canadian pharmaceutical research and innovation. Hancock is being recognized for pioneering work unravelling the complex interactions between antibiotics and bacteria.

New fiber-optic device can deliver light to the brain in 3D

A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts Institute of Technology (MIT) in Cambridge, is the first tool that can deliver precise points of light to a 3-D section of living brain tissue. The work is a step forward for a relatively new but promising technique that uses gene therapy to turn individual brain cells on and off with light.

D737 compound restores motor function and longevity in fruit flies with Alzheimer's

An efficient, high-volume technique for testing potential drug treatments for Alzheimer's disease uncovered an organic compound that restored motor function and longevity to fruit flies with the disease, according to new research that could help put the search for an effective Alzheimer's drug on a faster track.

Study finds specific way in which Salmonella counteract defense mechanisms of human cells

A new study by researchers at Imperial College London has identified a way in which Salmonella bacteria, which cause gastroenteritis and typhoid fever, counteract the defence mechanisms of human cells.

Researchers discover unlikely recipe to kill antibiotic resistant bacteria

Washington State University researchers have found an unlikely recipe for antibiotic resistant bacteria: Mix cow dung and soil, and add urine infused with metabolized antibiotic. The urine will kill off normal E. coli in the dung-soil mixture. But antibiotic-resistant E. coli will survive in the soil to recolonize in a cow's gut through pasture, forage or bedding.

Is it safe to drink alcohol when taking antibiotics?

In the lead up to summer party season, NPS MedicineWise is reminding Australians that while alcohol might not interact with many antibiotics, it’s still important to follow certain rules for taking antibiotics correctly.

Flu virus suppresses body's ability to defend against bacteria

When infected with influenza, the body becomes an easy target for bacteria. The flu virus alters the host's immune system and compromises its capacity to effectively fight off bacterial infections. Now, a team of immunologists at the Helmholtz Centre for Infection Research (HZI) and cooperation partners has discovered that an immune system molecule called TLR7 is partly to blame. The molecule recognizes the viral genome - and then signals scavenger cells of the immune system to ingest fewer bacteria.

UiO researchers discover enzyme critical for spread of cancer

Enzyme hunters at UiO have discovered the function of an enzyme that is important in the spreading of cancer. Cancer researchers now hope to inhibit the enzyme.

Triclosan can contribute to increased risk of allergies in children

Triclosan - an antibacterial chemical found in toothpaste and other products - can contribute to an increased risk of allergy development in children. This comes from the Norwegian Environment and Childhood Asthma Study, in which the Norwegian Institute of Public Health is involved. Similar results are reported in the USA.
