A member of Glass’s research group inoculates an apple with Listeria. The fruit is then used to make caramel apples, at which time they are tested for the bacteria. This provides insight into the potential for caramel apples to cause illness among consumers.

Whole genome sequencing is a tool to determine an organism’s full complement of genetic material, or the entire DNA […]
