Honeybee colony collapse is a sanitary and ecological worldwide problem. The features of this syndrome are an unexplained disappearance of adult bees, a lack of brood attention, reduced colony strength, and heavy winter mortality without any previous evident pathological disturbances. To date there has not been a consensus about its origins. This report describes the clinical features of two professional bee-keepers affecting by this syndrome. Anamnesis, clinical examination and analyses support that the depopulation in both cases was due to the infection by Nosema ceranae (Microsporidia), an emerging pathogen of Apis mellifera. No other significant pathogens or pesticides (neonicotinoids) were detected and the bees had not been foraging in corn or sunflower crops. The treatment with fumagillin avoided the loss of surviving weak colonies. This is the first case report of honeybee colony collapse due to N. ceranae in professional apiaries in field conditions reported worldwide.
蜜蜂蜂群崩溃病是一个全球性的卫生和生态问题。这种综合征的特征是成年蜜蜂无缘无故地消失，对幼虫照顾不周，蜂群实力减弱，冬季死亡率高，而此前没有明显的病理紊乱。迄今为止，其起源尚无定论。本报告描述了两名受该综合征影响的职业养蜂人的临床特征。病史、临床检查和分析支持这两种情况的蜂群减少是由于感染了微孢子虫（Nosema ceranae），这是一种新兴的蜜蜂病原体。没有检测到其他重要的病原体或杀虫剂（新烟碱类），而且蜜蜂没有在玉米或向日葵作物上觅食。使用灭滴灵治疗避免了幸存的弱势蜂群的损失。这是首例在田间条件下，由 N. ceranae 引起的职业养蜂场蜜蜂蜂群崩溃的病例报告。
