Study demonstrates rapid diagnosis of urinary tract infections with biosensor technology

For the millions of people who suffer from urinary tract infections each year and the doctors who treat them, a promising new biosensor technology has been developed that may replace antiquated testing methods and save precious health care dollars.

In a recent clinical study conducted by the David Geffen School of Medicine at UCLA and the Veterans Affairs Greater Los Angeles Healthcare System, researchers used a biosensor developed by corporate partner GeneFluidics to identify correctly the infection-causing gram negative bacteria species in 98 percent of the tested clinical urinary tract infection urine samples. These results represent the first ever species-specific detection of bacteria in human clinical fluid samples using a microfabricated electrochemical sensor array.

Of equal significance, the new test provided results in 45 minutes, compared to two days with conventional methods.

The research, reported in the February 2006 issue of the peer-reviewed Journal of Clinical Microbiology, investigated a new technology to solve an old problem: the diagnosis of urinary tract infections -- the second most common bacterial infection -- in a clinically relevant timeframe.

In current laboratory practice, contaminating pathogens in urine specimens are grown in culture dishes until they can be visually identified. The major drawback of this century-old technique is the two-day time lag between specimen collection and bacteria identification. As a result, physicians must decide whether to prescribe antibiotic therapy and, if so, which type of bacteria to treat -- all without knowing the cause of the infection, if any. In contrast, the new biosensor technology would allow physicians to prescribe targeted treatment without the wait.

"Our research also showed that GeneFluidics' biosensor avoided problems inherent in alternative molecular approaches, such as PCR, that require the repeated copying of bacterial DNA or RNA prior to testing. W
