Nosema disease is the most widespread adult bee disease in the world.
There are no classic signs of the disease, and hence it frequently goes undetected.
Heavily infected bees live only half as long as non-infected bees.
Nosema disease is most likely present in all colonies all the time, and only likely to cause bee losses when conditions favour the micro-organism.
