Quick test finds signs of diarrheal disease caused by cryptosporidiosis

Infection Control Today, February 6, 2014

Bioengineers at Rice University and UTMB have developed a simple, highly sensitive and efficient test for the diarrheal disease cryptosporidiosis that could have great impact on global health. Results from the diagnostic developed by the lab of Rice bioengineer Rebecca Richards-Kortum are read from a paper strip that resembles a pregnancy test. Lines on the strip tell whether samples taken from the stool of a patient contain genetic DNA from the parasite that causes the disease. A. Clinton White, director of the infectious disease division at UTMB, asked Richards-Kortum to help develop a diagnostic test for the parasite. “I’ve been working with cryptosporidium for more than 20 years, so I wanted to combine her expertise in diagnosis with our clinical interest,” he says. “Recent studies in Africa and South Asia by people using sophisticated techniques show this organism is a very common, underappreciated cause of diarrheal disease in underresourced countries.” The news also appears in the Houston Chronicle and Science Codex.
