Wolbachia infection invades Aedes aegypti mosquito, blocks dengue transmission

Strains of a bacterium commonly found in fruit flies can prevent the Aedes aegypti mosquito from transmitting the virus that causes dengue fever, researchers have found.

Researchers trace source of latest cholera pandemic

Researchers have used next generation sequencing to trace the source and explain the spread of the latest (seventh) cholera pandemic. They have also highlighted the impact of the acquisition of resistance to antibiotics on shaping outbreaks and show resistance was first acquired around 1982.

ICU patients with MRSA infection may face 50% increased risk of death

Does the Methicillin-resistant Staphylococcus aureus, MRSA, cause more deaths in hospitals than the bacteria that are sensitive to common antibiotics? Opinions have been varied, but now a worldwide study at, among others, Linköping University in Sweden, indicates that the mortality rate can be 50 % higher for intensive care patients infected with MRSA.

Researchers discover NPC1 protein as crucial for Ebola virus to enter host cells

Although outbreaks are rare, Ebola virus, the cause of Ebola hemorrhagic fever (EHF), is one of the deadliest known viruses affecting humans. According to the World Health Organization (WHO), approximately 1,850 EHF cases with more than 1,200 deaths have been documented since the virus was identified in 1976.

Azithromycin can effectively reduce acute COPD exacerbations

A common antibiotic added to the usual treatment plan for some patients with chronic obstructive pulmonary disease can reduce acute exacerbations — sudden onsets of worsened cough, wheezing and labored breathing — and improve quality of life, according to findings from the COPD Clinical Research Network reported in the Aug. 25, 2011, issue of the New England Journal of Medicine.

A pain-free way of tackling dental decay

Researchers at the University of Leeds have discovered a pain-free way of tackling dental decay that reverses the damage of acid attack and re-builds teeth as new.

Bacteria tweak their genes and proteins to gain strength

Scientists have discovered that bacteria like E. coli and Salmonella have a sneaky way of making minor alterations to their genes to boost their chances for infection.

Afghan patients treated at U.S. military hospitals often carry MDR bacteria

Afghan patients treated at a U.S. military hospital in Afghanistan often carry multidrug-resistant (MDR) bacteria, according to a report in the September issue of Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.

Researchers discover expression of IL-37 that protects mice from colitis

Inflammatory bowel disease (IBD), which affects more than 1 million patients in North America, results from an uncontrolled immune response triggered by environmental factors, such as bacteria, in people genetically predisposed to the disorder. Ulcerative colitis, or inflammation of the lining of the colon, is one such condition.

Hospital acquired Clostridium difficile bug defense system identified

American researchers have discovered the process by which the cells in the gut fight off toxins produced by a hospital bug - Clostridium difficile. Writing in Nature Medicine, they showed how a chemical - GSNO - deactivated a toxin from Clostridium difficile which causes inflammation and diarrhea. They hope to use their findings to develop a treatment for C. difficile.

No effective treatment yet for acute lung injury

Patients can essentially drown in their own fluids when trauma and infection prompt blood vessels to leak, flooding millions of air sacs in their lungs.

Micro-organisms hide themselves from immune defences

That micro-organisms have a great capacity to vary their surface structure is well known. It is one of the reasons why it is so difficult to develop vaccines against HIV and malaria, and why new influenza vaccines have to be produced every year. But it seems that these micro-organisms are also able to completely avoid activating a strong immune response in the person attacked.

Research uncovers natural defense mechanism that inactivates C. diff toxins

Groundbreaking research encompassing Case Western Reserve University School of Medicine and University Hospitals Case Medical Center, has uncovered a natural defense mechanism that is capable of inactivating the toxin that spreads Clostridium difficile, or C. diff, an increasingly common bacterial infection in hospitals and long-term care settings.

Researchers develop new methods to identify potential sources of food contamination

Unwanted bacteria, yeasts and moulds can cause major problems for the food industry as well as consumers. Norwegian researchers have developed new methods to identify potential sources of contamination.

Scientists discover key defense mechanism against C. difficile infection

Researchers have discovered a key mechanism used by intestinal cells to defend themselves against one of the world's most common hospital-acquired bacterial infections - a mechanism they think they can exploit to produce a therapy to protect against the effects of the antibiotic-resistant bacteria.

Radiolabeled protein reveals presence of S. aureus endocarditis in mouse model

A novel imaging probe developed by Massachusetts General Hospital (MGH) investigators may make it possible to diagnose accurately a dangerous infection of the heart valves.

New CDI therapeutic approach may offer treatment for other bacterial diseases

Researchers at the David Geffen School of Medicine at UCLA and the University of Texas Medical Branch at Galveston have discovered a molecular process by which the body can defend against the effects of Clostridium difficile infection (CDI), pointing the way to a promising new approach for treating an intestinal disease that has become more common, more severe and harder to cure in recent years.

Scientists reveal how thiostrepton blocks FOXM1 protein, prevents breast cancer development

Scientists have discovered how a molecule that was first discovered in bacteria blocks a protein which causes breast cancer to develop and spread, reveals research published in Nature Chemistry today.

New York College of Health Professions to inaugurate second Manhattan location

New York College of Health Professions, a private institutionally accredited college based in Syosset, N.Y., with a facility in Luo Yang, China, today announced the opening of its second Manhattan location at the University Settlement on Houston Street and Bowery in Chinatown.

Dog fecal material may constitute the dominant source of airborne bacteria

Bacteria from fecal material -- in particular, dog fecal material -- may constitute the dominant source of airborne bacteria in Cleveland's and Detroit's wintertime air, says a new University of Colorado Boulder study.
