Nosemosis disease of the honey bee, Apis mellifera L., is spreading worldwide and causes severe economic losses in apiculture. A. mellifera was previously considered to be infected by Nosema apis, which causes a decrease in honey bee life span and reduces colony strength. However recently the congeneric N. ceranae known as a microsporidium of the Asian honey bee A. cerana has been found in A. mellifera colonies as well. During the last 10 years, N. ceranae infection in honey bees has become considerably more prevalent than N. apis infection in several European countries.
