St. A team of scientists from St. Petersburg State University, the National Scientific Center for Marine Biology named after AV Zhirmunsky of the Far Eastern Branch of the Russian Academy of Sciences and the Kandalaksha State Nature Reserve proved that infectious Pacific mussel cancer is dangerous for humans. and other animals entered Europe via the Northern Sea Route, along with diseased mussels, as a result of contamination of the bottoms of ships. The Ministry of Education and Science of the Russian Federation told socialbites.ca about this.
In mussels of the genus Mytilus (the most important commercial invertebrates), two genetic lines of aggressive infectious cancer have been identified: BTN1 and BTN2. Both are descendants of the Pacific mussel Mytilus trossulus. This cancer is contagious and is transmitted to shellfish through live cancer cells. Moreover, they have a genotype associated with the “patient zero” genotype, so they can be distinguished from spontaneous cancer by genotyping.
Commercial shellfish populations are susceptible to deadly cancer outbreaks, the primary cause of which is BTN. Epidemic diseases now threaten mussel seafood in Europe and the Atlantic sector. This situation can cause serious economic problems in the development of bivalve aquaculture.
Scientists decided to prove the existence of BTN in the Kola Bay of the Barents Sea. All BTNs found in Kola Bay belonged to the North Pacific strains of the disease, which has not previously been observed outside the North Pacific.
Research on BTN has been ongoing since its discovery in 2015. They have theoretical and practical importance. Scientists say this infectious cancer potentially threatens all metazoans, including humans, so basic knowledge about this infection is needed.
Previous researchers taught Artificial intelligence to diagnose skin cancer.
