Caspase-11 enzyme plays an important role in Legionella infection

New research shows that an enzyme that has long been considered relatively useless to the immune response instead has an important role in setting up immune cells to kill infection-causing bacteria.

Billions of specific gut bacteria may play a role in autoimmune diseases

The billions of bugs in our guts have a newfound role: regulating the immune system and related autoimmune diseases such as rheumatoid arthritis, according to researchers at Mayo Clinic and the University of Illinois at Urbana-Champaign.

Gut microbes regulate brain levels of serotonin

UCC scientists have shown that brain levels of serotonin, the 'happy hormone' are regulated by the amount of bacteria in the gut during early life. Their research is being published today in the leading international psychiatry journal, Molecular Psychiatry.

Hospitalization rates in NYC for patients with CA-MRSA more than tripled between 1997-2006

Hospitalization rates in New York City for patients with community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), a potentially deadly bacterial infection that is resistant to antibiotic treatment, more than tripled between 1997 and 2006, according to a report published in the July issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.

New approach can design antibiotics that kill even 'superbugs'

The world needs new antibiotics to overcome the ever increasing resistance of disease-causing bacteria - but it doesn't need the side effect that comes with some of the most powerful ones now available: hearing loss. Today, researchers report they have developed a new approach to designing antibiotics that kill even "superbugs" but spare the delicate sensory cells of the inner ear.

Premature cancer death risk may be increased by dental plaque

Persistent dental plaque may increase the risk of dying early from cancer, suggests an observational study published in the online journal BMJ Open.

Study shows how infections provoke tissues into becoming cancerous

One of the biggest risk factors for liver, colon or stomach cancer is chronic inflammation of those organs, often caused by viral or bacterial infections. A new study from MIT offers the most comprehensive look yet at how such infections provoke tissues into becoming cancerous.

Routine screening with echocardiogram can detect more cases of RHD

Routine screening with echocardiogram can detect three times as many cases of rheumatic heart disease (RHD) as clinical examinations, offering a novel approach in preventing this common disease, according to a new study in Circulation.

Aminoacyl-tRNA synthetases important targets for development of new drugs against major diseases

Researchers at the University of Gothenburg, Sweden, are working to develop substances that can prevent parasites, bacteria and fungi from producing essential proteins, research that could, in the long term, lead to new drugs for several major diseases.

Study documents altruistic behavior by human embryonic stem cells

When most groups of mammalian cells are faced with a shortage of nutrients or oxygen, the phrase "every man for himself" is more apt than "all for one, one for all." Unlike colonies of bacteria, which often cooperate to thrive as a group, mammalian cells have never been observed to help one another out. But a new study led by a researcher at the Stanford University School of Medicine has shown that certain human embryonic stem cells, in times of stress, produce molecules that not only benefit themselves, but also help nearby cells survive.

Scientists discover new genetic information linked with shigellosis

Scientists have found new genetic information that shows how harmful bacteria cause the acute diarrheal disease shigellosis, which kills more than a million people worldwide each year.

Subtype of CD4-positive immune cells in the gut may influence HIV infection outcome

The findings of a new study in monkeys may help clarify why some people infected with HIV are better able to control the virus. They also may pinpoint a target for treatment during early HIV infection aimed at increasing the supply of certain immune cells in the gut, which the study shows could be an important factor in limiting HIV growth in cells throughout the body.

Scientists image structure of bacterium protein coat

Bacteria are omnipresent - in the water, the air and the soil, as well as in plants, animals and even people. We tend to think of bacteria as pathogenic, causing disease. We associate them with intestinal upsets and throat infections, pneumonia and blood poisoning.

Project aims to reduce transmission of infectious diseases on aircraft

A new study is expected to provide the first detailed information on how infectious diseases may be transmitted aboard commercial airliners. Sponsored by aircraft manufacturer Boeing, the research will document patterns of passenger movement inside aircraft cabins and inventory the microbes present in cabin air and on surfaces such as tray tables and lavatory fixtures.

Scientists unravel one important secret of bacterial adaptation

Learning the secrets of how pathogenic bacteria manage to survive in the body of an animal or human may carry great implications for future development of new and better medical treatments. Now, scientists at the University of Maryland School of Dentistry have unraveled one important secret of bacterial adaptation.

Experimental drug tested against multi-drug resistant TB

"Researchers who tested a novel type of antibiotic against multi-drug-resistant tuberculosis [MDR-TB] are reporting that nearly half of patients who got the new drug cleared the bacteria from their lung fluid in two months," according to a study published Thursday in the New England Journal of Medicine, Reuters reports.
