Viral suspect for amphibian decline traced to human spread through bait
A genetic study indicates that a virus known to be partially responsible for the global disappearance of amphibians may have been transmitted through the bait trade - by infected salamanders being distributed and introduced to remote, uncontaminated environments by interstate bait wholesalers and fishermen.
