Vaccine to prevent Campylobacter in chickens can help reduce food-borne illness

A vaccine could be developed to prevent Campylobacter being carried in chickens. This approach could drastically cut the number of cases of food poisoning, saving the UK economy millions each year, says an American scientist presenting his work at the Society for General Microbiology's Spring Conference in Dublin.

Ripeness of fruit determines how food-poisoning bacteria grow on them

The ripeness of fruit could determine how food-poisoning bacteria grow on them, according to scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week. Their work could lead to new strategies to improve food safety, bringing many health and economic benefits.

Commensal bacteria may play an important role in influencing and controlling allergic inflammation

When poet Walt Whitman wrote that we "contain multitudes," he was speaking metaphorically, but he was correct in the literal sense. Every human being carries over 100 trillion individual bacterial cells within the intestine -- ten times more cells than comprise the body itself.

Bacteriophages can tackle drug-resistant bacterial infections

Viruses that can target and destroy bacteria have the potential to be an effective strategy for tackling hard-to-treat bacterial infections. The development of such novel therapies is being accelerated in response to growing antibiotic resistance, says Dr David Harper at the Society for General Microbiology's Spring Conference in Dublin.

Nerve pain patients in Wales gain access to first of a kind treatment which can provide lasting pain relief

For the first time NHS patients in Wales with peripheral nerve pain (known as peripheral neuropathic pain) can be treated with a patch containing capsaicin, which can provide at least 12 weeks pain relief following a single 30- or 60-minute application.

Multiresistant bacteria withstand wastewater treatment processes

Large quantities of antibiotic-resistant bacteria enter the environment via municipal - and especially hospital - wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous - multiresistant - strains appear to withstand or even to be promoted by treatment processes. This was demonstrated by Eawag researchers in a study carried out in Lake Geneva, near Lausanne.

Bronchoscopy helps distinguish phenotypes, personalize therapy for refractory asthma

Using a bronchoscope to visually examine the airways and collect fluid and tissue can help guide effective therapy for difficult-to-treat asthma patients, according to researchers at National Jewish Health.

Study finds higher death rate in calorie-restricted models of IBD

In a surprising result, Michigan State University researchers looking at the effects of diet on bowel disease found that mice on a calorie-restricted diet were more likely to die after being infected with an inflammation-causing bacterial pathogen in the colon.

Elevated Aβ peptide levels may lead to onset of AD

The effects of the bacterial endotoxin lipopolysaccharide (LPS) has been found to elevate amyloid beta (Aβ) peptide levels in the brain, leading to short-term deficits in learning.

New perspective on why the immune system makes us worse while trying to make us well

A new article in The Quarterly Review of Biology helps explain why the immune system often makes us worse while trying to make us well.

Common pain relievers could cause hypertension

Diseases such as kidney failure and endocrine tumors are among the suspects causing high blood pressure - but could the common pain relievers in your medicine cabinet be the culprit? According to Prof. Ehud Grossman of Tel Aviv University's Sackler Faculty of Medicine and the Sheba Medical Center, many common over-the-counter and prescription medications are underlying causes of hypertension, which is a major risk factor for stroke, heart attack, and aneurisms.

IDSA releases new rhinosinusitis guidelines

The vast majority of sinus infections are caused by viruses and should not be treated with antibiotics, suggest new guidelines released by the Infectious Diseases Society of America.

FDA, Agilent partner to develop new tools for detection of salmonella subtypes

Agilent Technologies Inc. today announced that it has entered into a Cooperative Research and Development Agreement with the U.S. Food and Drug Administration to develop new tools to detect and analyze pathogens in food.

New antibiotic shows promise against bovine mastitis

Food-borne diseases might soon have another warrior to contend with, thanks to a new molecule discovered by chemists at the University of Illinois. The new antibiotic, an analog of the widely used food preservative nisin, also has potential to be a boon to the dairy industry as a treatment for bovine mastitis.

Study identifies new hypervariable regions in human gut viruses

A growing body of evidence underscores the importance of human gut bacteria in modulating human health, metabolism, and disease. Yet bacteria are only part of the story. Viruses that infect those bacteria also shape who we are. Frederic D. Bushman, PhD, professor of Microbiology at the Perelman School of Medicine at the University of Pennsylvania, led a study published this month in the Proceedings of the National Academy of Sciences that sequenced the DNA of viruses -- the virome -- present in the gut of healthy people.

Klf4 protein an important regulator of inflammation: HNK study

Microglia are the first line defence of the brain and are constantly looking for infections to fight off. Overactive microglia can cause uncontrolled inflammation within the brain, which can in turn lead to neuronal damage. New research published in BioMed Central's open access journal Journal of Neuroinflammation shows that, honokiol (HNK) is able to down-regulate the production of pro-inflammatory cytokines and inflammatory enzymes in activated microglia via Klf4, a protein known to regulate DNA.

New EU project to assess risk of contaminated food brought in from other countries

The EHEC crisis in Germany in 2011 proved that food brought in from other countries can potentially carry agents that cause life-threatening diseases. Nevertheless, there have been extremely few investigations of the actual danger posed by germs that enter the EU along with food. The gap is now to be addressed by a new project, with the EU providing almost three million Euro to cover the costs.
