Until the mid-1990s, the only microsporidium known to infect bees of the genus Apis was Nosema apis. A second species, N. ceranae, was first identified in 1996 from Asian honey bees; it is postulated that this parasite was transmitted from the Asian honey bee, Apis cerana, to the European honey bee, Apis mellifera. Currently, N. ceranae is found on...
