Nosema spp. (Dissociodihaplophasida; Nosematidae) is known to be a parasitc microsporidian and the causative agent of nosemose. [1] The infectious non-germinated spore of the pathogen is transmitted through the oral-faecal route of workers to queens and brood or through mating. The most popular treatment is "fumagillin". While N. apis has a relatively wide distribution with a prevelence 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 Centre (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 concludet, that this disease is considered to be a negligible risk for Ethiopian honey bee colonies. [3][4] [2]


Indonesia: N. ceranae is present but there is a lack of data regarding the dangerousness or treating of the pathogen, indicating that Nosema represents a negligible risk in Indonesia. [5] [4] [6]
