Multiple lineages of transmissible neoplasia in the basket cockle (C. nuttallii) with repeated horizontal transfer of mitochondrial DNA

Abstract: Transmissible cancers are clonal lineages of neoplastic cells able to infect multiple hosts, spreading through the environment as an infectious disease. Transmissible cancers have been identified in Tasmanian devils, dogs, and bivalves. Several lineages of bivalve transmissible neoplasias (BTN) have been identified in multiple bivalve species. In 2019 in Puget Sound, disseminated neoplasia was observed in basket cockles (Clinocardium nuttallii), a species that is important to the culture and diet of the Suquam… Show more

“…Transmissible cancers are caused by malignant cell lineages that have acquired the ability to infect new hosts through the transmission of living cancer cells. Fourteen transmissible cancer lineages have been described to date: one in dogs (canine transmissible venereal tumour, CTVT [1,2]), two in Tasmanian devils (devil facial tumour, DFT1 and DFT2 [3,4]) and 11 in different marine bivalve species (bivalve transmissible neoplasia, BTNs [510]). While direct contact is necessary for CTVT and DFT transmission, via coitus for the former and biting for the latter, the transmission of BTNs between shellfish is assumed to occur through the seawater column [11,12].…”
