KANSAS: Rapid test for pathogens developed by K-State researchers could be used to detect diseases used by bioterrorists - (K-State Media)
August 21, 2008 – 8:49 pmMANHATTAN — Dangerous disease often spreads faster than it takes to diagnose it in the lab. To remedy that, researchers at Kansas State University have developed a test to bring that time from days down to hours.
Sanjeev Narayanan, assistant professor, and Greg Peterson, research microbiologist, both in the department of diagnostic medicine and pathobiology, use a device called a DNA spotted microarray to seek out the specific genetic markers that set one pathogen apart from another and determine antibiotic resistance.
Traditionally, it takes days and multiple lab workers to screen a sample of soil, water or feces for just one pathogen. Additional time is then needed to look for resistance to antibiotics. The new test developed at
K-State simultaneously looks for multiple diseases and antibiotic resistance, reducing the time it takes from sampling to diagnosis to about 24 hours.
“We needed a mass, high through-put system,” Narayanan said. “The longer a serious disease […]
