Dysentery

Dysentery is a diarrhea-like condition in honey bees, caused by the buildup of an excessive amount of fluid in the bee's gut and the inability of the bee to retain waste products in its body as it would normally. Bees will discharge their feces on the combs, in front of the hive entrance, and on the exterior of the hive. Colonies living in moist areas or in areas with poor air drainage will more frequently exhibit signs of dysentery. It is also caused by nosema disease, prolonged confinement during the winter, and early spring consumption of food with high water content.
