Using a small and inexpensive biosensor, researchers in the School of Engineering have developed a novel low-cost technique that quickly and accurately detects cryptosporidium contamination in water samples.
Cryptosporidium is an intestinal pathogen and one of the leading causes of respiratory and gastrointestinal illness in the world. Drinking water contaminated with the parasite can result in diarrhea and, in extreme cases, can even lead to death.
Methods - Cryptosporidium - Require - Volumes - Water
"Current methods for detecting cryptosporidium require filtering large volumes of water, separating out the organisms, staining them with a fluorescence label and trying to identify the pathogen using a microscope," says George Luka, a doctoral student at UBC Okanagan's School of Engineering and study lead author. "The process is extremely slow, expensive and doesn't yield reliable results."
Luka says there is an urgent need to develop a fast, flexible, accurate and real-time detection tool to meet the challenge of protecting...
