Origin of Haiti cholera epidemic traced to South Asia

The strain of cholera currently sweeping through post-earthquake Haiti originated in South Asia, conclude scientists who did a rapid genetic analysis of bacteria collected from Haitian patients. The finding supports the notion that the cholera bacteria fueling the outbreak arrived on the island via recent visitors.

Tru-D UV-C device effective in reducing pathogens on all environmental surfaces in hospital patient rooms

Results of an eight-month hospital study, "Room Decontamination with UV Radiation," were published in the October 2010 issue of "Infection Control and Hospital Epidemiology." The study evaluated the ability of an automated UV device, Tru-D, to decontaminate patient rooms contaminated with MRSA, VRE, C. difficile and a MDR strain of Acinetobacter baumannii.

Some key molecular events in immune system contribute to inflammatory bowel disease: Scientists

Scientists at the Virginia Bioinformatics Institute at Virginia Tech have discovered some of the key molecular events in the immune system that contribute to inflammatory bowel disease. The results, which help researchers move one step further in their efforts to develop new drugs to treat inflammatory and immune-mediated diseases, are reported in the November 2010 edition of the journal Mucosal Immunology from the Nature Publishing Group.

Bacterium used to tackle Dengue fever

This January Australian scientists will start deploying a strange bacterium called Wolbachia pipientis in an attempt to halt disease transmission by mosquitoes especially Dengue fever. They are targeting the Aedes aegypti mosquito that transmits Dengue. Dengue is a viral disease that leads to high fever, severe muscle and joint pain and can also be fatal.

Excreted antibiotics become potential sources of antibiotic resistant genes

When an antibiotic is consumed, researchers have learned that up to 90 percent passes through a body without metabolizing. This means the drugs can leave the body almost intact through normal bodily functions.
