Free online training Webinars to prepare nurses for continued relief efforts in Haiti launched

While disaster response is a highly technical and sensitive effort, the most qualified of disaster professionals require additional education or real-life experience to ensure that help is delivered effectively, safely and efficiently. To assist nursing professionals volunteering their services in Haiti, Chamberlain College of Nursing in cooperation with the Johnson & Johnson Campaign for Nursing's Future, will provide free online training Webinars hosted on the Gannett Healthcare Group's newly launched Haiti Web page to prepare nurses physically, mentally and culturally for the continued relief efforts.

Humans can harbor bacteria in gallstones, infect others with active typhoid fever

A new study suggests that the bacteria that cause typhoid fever collect in tiny but persistent communities on gallstones, making the infection particularly hard to fight in so-called "carriers" - people who have the disease but show no symptoms.

First high-throughput analysis of Salmonella Typhi gene

For the first time, researchers are able to look at the need for every gene in a bacterial cell in a single experiment. The new method will transform the study of gene activity and the search for weaknesses in bacterial armouries.

URV’s biosensor can detect typhoid causing bacteria instantly

A research group from the Rovira i Virgili University (URV) in Tarragona has developed a biosensor that can immediately detect very low levels of Salmonella typhi, the bacteria that causes typhoid fever. The technique uses carbon nanotubes and synthetic DNA fragments that activate an electric signal when they link up with the pathogen.

New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.
