Seaports discovered to be hotspots of infectious cancer in mussels

Seaports serve as centers for the international spread of MtrBTN2, an unusual infectious cancer impacting mussels. In this illness, cancer cells can be sent, like parasites, from one mussel to another neighboring.

While, in nature, such contagion primarily happens in between mussels in the very same bed, ports and maritime transportation help with the spread of MtrBTN2 to other areas, through biofouling, where infected mussels connect themselves to deliver hulls.

This finding, the fruit of research study by a group led by researchers from the CNRS and the University of Montpellier, was released in Procedures of the Royal Society B on February 21.

Greater occurrence of the illness in ports was kept in mind after studying 76 mussel populations along the coast of southern Brittany and the Vendée, within both natural and synthetic environments.

The research study group asserts that their discovery argues in favor of biofouling mitigation policies, to stem the spread of the illness and maintain seaside communities.
