Deletion of a protein improves ability to fight bacteria in mice with CGD

Deletion of a protein in white blood cells improves their ability to fight the bacteria staphylococcus aureus and possibly other infections in mice with chronic granulomatous disease (CGD), according to a National Institutes of Health study. CGD, a genetic disorder also found in people, is marked by recurrent, life-threatening infections. The study's findings appear online in The Journal of Clinical Investigation.

Chemicals added to swimming pool water can cause irritation, injury and even death, doctors warn

Chemicals are added to swimming pool water to enhance and protect the water quality and minimize disease-causing germs, but these same chemicals can cause irritation, injury and even death when not handled appropriately, doctors at Vanderbilt University Medical Center warn.

Scientists solve structure of infection tool used by Yersinia bacterium

Abdominal pain, fever, diarrhoea -- these symptoms could point to an infection with the bacterium Yersinia. The bacterium's pathogenic potential is based on a syringe-like injection apparatus called injectisome.

Washing down sugary breakfast cereal with milk after eating may prevent cavities

Washing down sugary breakfast cereal with milk after eating reduces plaque acid levels and may prevent damage to tooth enamel that leads to cavities, according to new research at the University of Illinois at Chicago College of Dentistry.

Researchers create computational model to track VRE spread among hospitals

A moderate increase in vancomycin-resistant enterococci (VRE) at one hospital can lead to a nearly 3 percent increase in VRE in every other hospital in that county, according to a study in the August issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology (APIC).

WHO aims to increase global rate of breastfeeding for six months to 50% by 2025

Only 37 countries, or 19% of those reporting, have passed laws reflecting all the recommendations of the International Code of Marketing of Breast-milk Substitutes, according to a new World Health Organization (WHO) report published during World Breastfeeding Week. The week is celebrated in more than 170 countries from 1 to 7 August.

Hope for treatment of childhood infections may come straight from the gut: Therapeutic poop

Call it therapeutic poop, if you will, but the best hope yet for an effective treatment of childhood infections with the drug-resistant bacterium C. difficile may come straight from the gut, according to recent research.

Research: Reducing antibiotics consumption does not necessarily reduce resistance

Antibiotic use-and misuse-is the main driver for selection of antibiotic resistant bacteria. This has led many countries to implement interventions designed to reduce overall antibiotic consumption. Now, using methicillin resistant Staphylococcus aureus (MRSA) as an example, Laura Temime of the Conservatoire National des Arts et Metiers, Paris, and collaborators warn that simply reducing antibiotics consumption does not necessarily reduce resistance.

Adaptimmune initiates Phase I/IIa open-label clinical trial in patients with ovarian cancer

Adaptimmune announced today that it has opened a Phase I/IIa, multiple-site, two-cohort, open-label clinical trial in ovarian cancer at Roswell Park Cancer Institute (RPCI) in Buffalo, N.Y., and City of Hope (COH) in Duarte, Calif.

New technology enables all of the world's crops to take nitrogen from the air

A major new technology has been developed by The University of Nottingham, which enables all of the world's crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.

Researchers explain how gut bacteria can inactivate cardiac drugs

For decades, doctors have understood that microbes in the human gut can influence how certain drugs work in the body - by either activating or inactivating specific compounds, but questions have long remained about exactly how the process works.

Researchers uncover way to stop cancer cells using HIF-1 gene through synthetic biology approach

Scientists have discovered a new molecule that prevents cancer cells from responding and surviving when starved of oxygen and which could be developed into new treatments for the disease, according to new research published in the Journal of the American Chemical Society today (Friday).

Abbott's FreeStyle Precision Pro Blood Glucose and Beta-Ketone Monitoring System gets FDA clearance

Abbott today announced that it has received U.S. Food and Drug Administration clearance for its FreeStyle Precision Pro Blood Glucose and Beta-Ketone Monitoring System, an advanced blood glucose monitoring system designed to address the key needs of hospital customers: high accuracy, efficient operation, dual-band wireless access to immediate test results, and helps in the reduction of the risk of test strip cross-contamination.

FDA allows marketing of Xpert MTB/RIF Assay for treatment of TB

The U.S. Food and Drug Administration today allowed marketing of the Xpert MTB/RIF Assay, the first FDA-reviewed test that can simultaneously detect bacteria that cause tuberculosis and determine if the bacteria contain genetic markers that makes them resistant to rifampin, an important antibiotic for the treatment of TB.

Research findings provide insight into safety of central line uses outside hospital

Pediatric cancer patients whose central lines are used to treat them at home develop three times as many dangerous bloodstream infections from their devices than their hospitalized counterparts, according to the results of a new Johns Hopkins Children's Center study.

Forced-air patient warming systems may affect airflows in OR; increase exposure to airborne contaminants

Forced-air systems used to keep patients warm during surgery may affect the performance of operating room (OR) ventilation systems-potentially increasing exposure to airborne contaminants, reports a study in the August issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

Discovery of pressure-driven infection mechanism opens door to new treatments for viral infections

The virus that causes those painful lip blisters known as cold sores has an internal pressure eight times higher than a car tire, and uses it to literally blast its infectious DNA into human cells, scientists are reporting in a new study.

Scientists develop simple, inexpensive and reliable method of detecting plague pathogen

Diagnosing the presence of Yersinia pestis, the cause of plague, may soon be easier than ever before. Scientists working with Peter Seeberger, Director at the Max Planck Institute of Colloids and Interfaces (MPIKG) in Potsdam and Professor at the Freie Universit-t Berlin, have come up with a simple, inexpensive and reliable method of detecting the bacterium.

Researchers discover mechanism that prevents immune system from spinning out of control

A team led by a University of Arizona researcher has discovered a previously unknown mechanism that prevents the immune system from going into overdrive, shedding light not only on how our body controls its response to pathogens but on conditions such as autoimmune diseases, allergies and chronic inflammation as well.
