The Research and Productivity Council in Fredericton has mapped the DNA of MSX. It brings them closer to knowing how to fight the disease that’s threatening the Atlantic oyster industry.

When scientists managed to isolated a single cell under a microscope months into their research on a deadly oyster disease, they knew they were onto something big.
“This is kind of a breakthrough,” said Attiq Rehman, director of bioscience at the Research and Productivity Council in Fredericton. “Nobody has ever done it.”
Rehman and colleague Rebecca Liston mapped a cell of MSX, a disease caused by a parasite that’s already contaminated oysters in the Northumberland Strait.
Not much was known about the parasite until this point.
