Fecal transplants restore healthy bacteria and gut functions

Fecal transplants restore healthy bacteria and gut functions

Fecal microbiota transplantation — the process of delivering stool bacteria from a healthy donor to a patient suffering from intestinal infection with the bacterium Clostridium difficile — works by restoring healthy bacteria and functioning to the recipient’s gut, according to a study published this week in mBio ®, the online open-access journal of the American Society for Microbiology.

Viral infections, including flu, could be inhibited by naturally occurring protein

Viral infections, including flu, could be inhibited by naturally occurring protein

By boosting a protein that naturally exists in our cells, an international team of researchers led by the University of Pittsburgh Cancer Institute (UPCI), partner with UPMC CancerCenter, has found a potential way to enhance our ability to sense and inhibit viral infections. The laboratory-based discovery, which could lead to more effective treatments for viruses ranging from hepatitis C to the flu, appears in the June 19 issue of the journal Immunity . The research is supported by the National Institutes of Health. Continue reading

Immune system precursor cells that fight infection discovered

Immune system precursor cells that fight infection discovered

The innate immune system recognizes infectious agents such as viruses and bacteria. A group of lymphocytes known as “innate lymphoid cells” or ILCs plays a central role in the defense of the human body against infective agents. Professor Andreas Diefenbach of the Research Center Immunology at the Mainz University Medical Center, working in collaboration with scientists at the University of Freiburg, has discovered previously unidentified ILCs that are able to protect epithelial surfaces, such as those of the intestinal mucosa, against infection.

Breakthrough in RSV research to help infected children

Breakthrough in RSV research to help infected children

Researchers at Le Bonheur Children’s Hospital and the University of Tennessee Health Science Center announced results today from a clinical trial of a drug shown to safely reduce the viral load and clinical illness of healthy adult volunteers intranasally infected with respiratory syncytial virus (RSV).

Researchers at Le Bonheur Children’s Hospital and the University of Tennessee Health Science Center announced results today from a clinical trial of a drug shown to safely reduce the viral load and clinical illness of healthy adult volunteers intranasally infected with respiratory syncytial virus (RSV). Detailed results of this study were presented by lead researcher Infectious Disease Specialist John DeVincenzo, MD, this week during a poster discussion session at the American Thoracic Society 2014 International Conference in San Diego.

Promising discovery in fight against antibiotic-resistant bacteria

Promising discovery in fight against antibiotic-resistant bacteria

Researchers at the University of British Columbia have identified a small molecule that prevents bacteria from forming into biofilms, a frequent cause of infections. The anti-biofilm peptide works on a range of bacteria including many that cannot be treated by antibiotics. Continue reading

Promising new target for gum disease treatment identified

Promising new target for gum disease treatment identified

Nearly half of all adults in the United States suffer from the gum disease periodontitis, and 8.5 percent have a severe form that can raise the risk of heart disease, diabetes, arthritis and pregnancy complications. University of Pennsylvania researchers have been searching for ways to prevent, half and reverse periodontitis. In a report published in the Journal of Immunology , they describe a promising new target: a component of the immune system called complement Continue reading

Windshield washer fluid a source of Legionnaires: Found in most school buses

Windshield washer fluid a source of Legionnaires: Found in most school buses

A form of bacteria responsible for respiratory illness, including the deadly pneumonia known as Legionnaire’s disease, may be able to grow in windshield washer fluid and was isolated from nearly 75% of school buses tested in one district in Arizona, according to research presented today at the annual meeting of the American Society for Microbiology. “Washer fluid spray can release potentially dangerous numbers of these bacteria into the air Continue reading
