A multi-state outbreak of urinary tract infections caused by drug-resistant Escherichia coli was probably due to consumption of a contaminated food product of animal origin, such as meat or milk, according to an article in the Jan. 15 issue of Clinical Infectious Diseases, now available online.
Urinary tract infections, or UTIs, are one of the most common infections in women. Although they are not typically considered "outbreak" diseases, it is likely that a cluster of UTIs resulting from the same drug-resistant strain of the bacterium E. coli came from a single source, such as a food animal.
Between October 1999 and January 2000, a single strain of E. coli was discovered to be responsible for drug-resistant UTIs in university communities in California, Minnesota, and Michigan. Researchers studied nearly 500 specimens of E. coli obtained from non-human sources such as cows, turkeys, dogs, sheep, and water. They found that one-quarter of the specimens were microbiologically indistinguishable from comparable human strains of E. coli. A more refined test showed that, of the drug-resistant specimens, one from a cow had a 94 percent similarity to a UTI-causing human strain of E. coli. The researchers concluded that the cause of the outbreak was probably foodborne.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
