Nosema spp. (Dissociodihaplophasida; Nosematidae) is known to be a parasitic microsporidian and the causative agent of nosemosis. [1] The infectious non-germinated spore of the pathogen is transmitted through the oral-faecal route of adult bees, or through mating. The most popular treatment in many countries is "fumagillin". While N. apis has a relatively wide distribution with a prevalence for colder climate, N. ceranae is mostly prevalent in the tropics and sub-tropics. [2]
Ethiopia: Nosema existence in Ethiopia has been reported for the first time in 1989 by the Holeta Bee Research Center (HBRC), Holeta. In a study by Desalegn and Amssalu (2015) over 200 honey bee colonies from all over Ethiopia were analysed and 37% were tested positive for N. apis. They further investigated the severity of an infestation and concluded, that this disease is considered to be a negligible risk for Ethiopian honey bee colonies. [2] [3][4] Nothing is known about the presence of N. ceranae in Ethiopia.
