Outline of Final Research Achievements

Honeybee nosemosis was designated in 1997 as a Monitored Infectious Disease by the Act on Domestic Animal Infectious Diseases Control published by the Minister of Agriculture, Forestry and Fisheries of Japan, and is a very crucial disease for Veterinary Medicine. However, the elucidation of the disease remains insufficient. This study clarified that the pathogen is not Nosema apis but Nosema ceranae and Nosema sp. in Tohoku district. The elucidation is very important for the disease prevention.

Academic Significance and Societal Importance of the Research Achievements

家畜伝染病予防法に指定されているミツバチ・ノゼマ病は獣医学的に重要な疾病であるにもかかわらず、同じ家畜である牛や豚などの家畜動物の感染症に比べて研究・解明は進んでいない。本研究により東北地方におけるノゼマ病の病原体が、指定されているNosema apisではなく、N. ceranaeおよびNosema sp.であることを明らかにしたことは本病の防遏対策を講じる上で極めて重要であり、学術的意義や社会的意義が大いにあると考えられる。
