Nosemosis is one of the most prevalent bee diseases in the world causing significant economic losses in the global bee-keeping industry. This cross-sectional study was conducted during April-September, 2016 to investigate the prevalence of nosemosis in different climatic regions of Iran. A total of 183 apiaries were selected based on cluster sampling and the climate of apiaries under study was classified using Domarten method. In each apiary, five percent of the colonies were randomly sampled. A total of 183 adult bee samples were taken and examined by microscopic and polymerase chain reaction (PCR) methods for the presence of infections. According to the results, infection caused by was observed in all regions under study. The prevalence of was 46.40% (42.70-50.10). However, infection with was not observed in the samples in either pure form or as associated infection. Based on the results of PCR, the prevalence of was 53.80% (46.60- 61.00) in humid, 71.00% (53.70-77.50) in semi-humid, 68.10% (61.40-74.80) in very humid, 29.40% (22.70-36.10) in arid, 34.30% (27.40-41.20) in semi-arid and 24.00% (17.90-30.00) in Mediterranean climates. The prevalence of infection in different climatic zones of the country was found to have significant differences ( < 0.001). According to the findings, was the only species in honeybees with a broad geographical dispersion in Iran. It seems that climate can influence the prevalence of mentioned parasite. .
微孢子虫病是世界上最普遍的蜜蜂疾病之一，给全球养蜂业造成了重大经济损失。这项横断面研究于2016年4月至9月进行，旨在调查伊朗不同气候区域微孢子虫病的流行情况。基于整群抽样选取了总共183个养蜂场，并使用多马滕方法对所研究养蜂场的气候进行分类。在每个养蜂场中，随机抽取5%的蜂群。总共采集了183个成年蜜蜂样本，并通过显微镜检查和聚合酶链反应（PCR）方法检测是否存在感染。根据结果，在所研究的所有区域均观察到由[具体病原体名称未给出]引起的感染。[具体病原体名称未给出]的感染率为46.40%（42.70 - 50.10）。然而，在所采集样本中未观察到[另一种病原体名称未给出]的单纯感染形式或合并感染形式。基于PCR结果，[具体病原体名称未给出]在潮湿气候区的感染率为53.80%（46.60 - 61.00），在半湿润气候区为71.00%（53.70 - 77.50），在非常湿润气候区为68.10%（61.40 - 74.80），在干旱气候区为29.40%（22.70 - 36.10），在半干旱气候区为34.30%（27.40 - 41.20），在地中海气候区为24.00%（17.90 - 30.00）。该国不同气候区的感染率存在显著差异（P < 0.001）。根据研究结果，[具体病原体名称未给出]是伊朗蜜蜂中唯一具有广泛地理分布的物种。气候似乎会影响上述寄生虫的流行率。
