Scientists in Indiana are reporting development of a new biosensor for use in a faster, more sensitive test for detecting the deadliest strain of Listeria food poisoning bacteria. That microbe causes hundreds of deaths and thousands of hospitalizations each year in the United States, particularly among people with weakened immune systems.
Arun Bhunia and colleagues note in the new study that fast, highly effective tests already are available for five of the six known species of Listeria. These tests use antibodies that signal the presence of the bacteria. However, no rapid, sensitive tests are available for detecting Listeria monocytogenes, the deadliest of the species, the researchers say.
