The Neomys fodiens (Eurasian water shrew) eDNA detection kit is able to detect the mammal species Neomys fodiens in all droppings and soil samples worldwide and contains enough materials for 20 samples to be analysed in 8 fold (200 qPCR tests). The kit is based on the fast, sensitive, and proven primers/probe qPCR technique. The kit contains primers and a probe for detecting a highly specific sequence present on the mitochondrial DNA of the species Neomys fodiens.
Be aware: Using soil as a sample has a chance of picking up ancient DNA of water shrews from years ago. DNA is highly stable connected to soil particles.
Species information
The Eurasian water shrew (Neomys fodiens), known in the United Kingdom as the water shrew, is a relatively large shrew, up to 10 cm (4 in) long, with a tail up to three-quarters as long again. It has short, dark fur, often with a few white tufts, a white belly, and a few stiff hairs around the feet and tail. It lives close to fresh water, hunting aquatic prey in the water and nearby. Its fur traps bubbles of air in the water which greatly aids its buoyancy, but requires it to anchor itself to remain underwater for more than the briefest of dives.
Like many shrews, the water shrew has venomous saliva, making it one of the few venomous mammals, although it is not able to puncture the skin of large animals, nor that of humans. Highly territorial, it lives a solitary life and is found throughout the northern part of Europe and Asia, from Britain to Korea.
