Bivalve Transmissible Neoplasia (BTN) is a rare type of cancer that affects certain shellfish, particularly soft-shell clams. Unlike traditional cancers that stay put, BTN cells have a flair for travel. They can jump from one clam to another, spreading cancer like a bad rumor at a family reunion.
What is BTN?
BTN is a serious disease that acts like a leukemia, which is a type of blood cancer, but instead of humans, it targets clams. This cancer has been found mainly on the east coast of North America, with known outbreaks in places like New England and Prince Edward Island. However, it recently started making headlines on the west coast in the Puget Sound area—talk about a cross-country trip!
How Does BTN Spread?
The magic (or mischief) of BTN lies in its ability to spread by cancer cells themselves. When a clam is infected, those cancer cells can move to other clams, allowing the disease to hop around like a game of tag. Once the cancer reaches a new clam, it can start making itself at home, often leading to high rates of infection in local populations.
The Latest Outbreak
In 2022, scientists discovered that BTN had arrived in the Puget Sound, where it was previously unheard of. They found it in two specific locations, and by 2024, over 75% of clams in those areas were infected. It seems this sneaky cancer took a long trip from the east coast, and it's not planning to leave anytime soon!
What’s Going On Inside the Clams?
Researchers have been looking closely at how this cancer manages to survive and thrive in new clams. It seems that BTN has learned some tricks over time. For instance, it can play dead (or at least act like it) when put in seawater, avoiding death while it waits to find a new host. Some of these survival methods are similar to how healthy clam cells respond in tough conditions, which is pretty clever if you think about it.
How Do We Track BTN?
Thanks to modern technology, scientists have created methods to look for signs of BTN in the environment. By examining seawater and clam samples, they can confirm the presence of the cancer, helping to map its spread. This way, they can stay one step ahead of the cancerous clams and work to protect healthy populations.
Conclusion
Bivalve Transmissible Neoplasia may sound like a complex term, but at its core, it's a unique cancer that defies many traditional rules. By spreading from clam to clam, it's caught researchers' attention and sparked concern about the health of shellfish populations. Who knew that clams could have such dramatic lives?
