Scientists in Wyndmoor, Pa., are improving methods to detect foodborne pathogens

"Listeriosis, the illness caused by L. monocytogenes infection, affects around 2,500 people in the United States every year, and kills about 500. Newborns, seniors, pregnant women and individuals with compromised or weakened immune systems are particularly susceptible.

Most methods for detecting harmful foodborne bacteria rely on antibodies, which are proteins used by the immune system to fight infections and foreign bodies. Because these antibodies target very specific infections, researchers can use them to identify and locate specific pathogens."
