Nanotechnology test for anthrax shows promise
A new nanotechnology test to quickly detect miniscule amounts of anthrax toxin showed promising results in an initial "proof of concept" study, the US Food and Drug Administration (FDA) said yesterday in a press release. The testing method, developed by FDA scientists, uses a europium nanoparticle-based immunoassay (ENIA) to detect a Bacillus anthracis protein that plays a key role in infecting cells. The researchers, who reported their findings in the March issue of Clinical and Vaccine Immunology, said ENIA detected the protein in amounts 100 times lower than can be detected with current tests, such as the enzyme-linked immunosorbent assay (ELISA).

Egypt finds H5N1 in backyard birds, poultry shipment
Animal health officials in Egypt recently reported four more H5N1 avian influenza outbreaks in poultry, three in backyard birds and one in a truckload of poultry, the Egypt-based Strengthening Avian Influenza Detection and Response (SAIDR) reported. The outbreaks in backyard birds were detected on Mar13 in Beheira, Sharkiya, and Sixth of October governorates.

Salmonella outbreak reaches 100 confirmed cases
The number of illnesses with confirmed connections to a multistate Salmonella Saintpaul outbreak, believed to be linked to sprouts, has grown to 100, with at least 43more probable cases, according to state health departments. Nebraska reported84 confirmed cases and 13 probable infections in a statement yesterday. Officials told CIDRAP News that Kansas has 6 confirmed cases and South Dakota has 5 confirmed cases and 26 probable ones. Iowa health officials said in a Mar3 statement that they had confirmed 5 cases and identified 4 probable cases. An epidemiologic investigation has linked the outbreak to sprouts, but tests have not yet confirmed them as the source. Sun Sprout Enterprises of Omaha has recalled three kinds of sprouts as a precaution.
Wireless tracking of hand washing
New low-power wireless "Zigbee" technology might be an inexpensive and useful tool for encouraging hand hygiene in healthcare workers, researchers from the University of Iowa reported today in San Diego at the annual meeting of the Society for Healthcare Epidemiology of America (SHEA). Workers wear pager-sized badges that permit automated tracking of their use of hand hygiene dispenser stations before entering and after leaving patient rooms. The automated system correctly flagged more than 90% of study subjects entering and leaving rooms if they remained there for at least 30 seconds.
