Should we be screening blood for hepatisi G?

Hepatitis G virus was identified in 1995. Some little research was carried out on the virus and the US Food and Drug Administration (FDA) declared it a non-harmful virus in 1997. Researchers in Saudi Arabia, writing in the International Journal of Immunological Studies present evidence to suggest that this may have been the wrong decision.

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.

Tiny molecule could bind to B cell EB12 receptor and prevent cancer

Infection with Epstein Barr means that the B cells, which are the primary memory cells of the immune system, are hi-jacked. When the virus has penetrated, researchers observe an excess of a special bio-antenna, a receptor known as EB12, suddenly sprouting from the surface of the B cells. But why they do so remains a mystery.

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.

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.

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.

Hospital roundup: Catholic facilities losing nuns' leadership; Georgia infection rates; new VA system for Louisiana

In 1968, nuns or priests served as chief executives of 770 of the country's 796 Catholic hospitals, according to the Catholic Health Association. Today, they preside over 8 of 636 hospitals. ... The leadership shift has stirred angst in many Catholic hospitals about whether the values imparted by the nuns, concerning the treatment of both patients and employees, can withstand bottom-line forces without their day-to-day vigilance.

VOA News examines new drug compound that shows broad-based efficacy in lab tests

VOA News looks at a new drug compound developed by researchers at the Massachusetts Institute of Technology (MIT) that they say has so far "killed every virus it's been tested on in the laboratory." "The drug - known by the acronym DRACO - works by chemically targeting viral-infected cells and prompting them to self-destruct, eliminating the disease in the process," VOA writes.

Researchers turn their attention to Chagas disease as developed countries see rise in infection rates

Chagas disease, a historically neglected tropical disease that the WHO estimates affects about 10 million people worldwide, is drawing increased attention as infection by the parasite spreads from Latin America to developed countries, such as Spain and the United States, Science reports.

Emory team identifies conditions that make memory T cells slip away during chronic infections

After recovering from the flu or another acute infection, your immune system is ready to react quickly if you run into the same virus again. White blood cells called memory T cells develop during the infection and help the immune system remember the virus and attack it if it comes back.
