微孢子虫是一种最初在亚洲蜜蜂Apis cerana中描述的微孢子虫寄生虫，最近发现它具有交叉感染性，也寄生在欧洲蜜蜂Apis mellifera中。自从这一发现以来，许多研究试图描述这种寄生虫对A.意大利蜜蜂微孢子虫可以感染所有的群体成员，工人，雄蜂和皇后，但这种微孢子虫的病理影响主要是在工人，尽管皇后的首要作用，谁垄断了繁殖和调节社会的凝聚力通过信息素。因此，我们分析了N.蜂后生理学的研究我们发现N.铈不影响脂肪体含量（能量储存的指标），但确实改变了卵黄原蛋白滴度（生育力和寿命的指标）、总抗氧化能力和蜂王下颌信息素，令人惊讶的是，这些在微孢子虫感染的蜂王中都显著增加。因此，这种生理变化可能会影响蜂王健康，导致信息素产生的变化，这可以解释微孢子虫诱导的取代（蜂王取代）。(C)2010年爱思唯尔公司All rights reserved.
Nosema ceranae, a microsporidian parasite originally described in the Asian honey bee Apis cerana, has recently been found to be cross-infective and to also parasitize the European honey bee Apis mellifera. Since this discovery, many studies have attempted to characterize the impact of this parasite in A. mellifera honey bees. Nosema species can infect all colony members, workers, drones and queens, but the pathological effects of this microsporidium has been mainly investigated in workers, despite the prime importance of the queen, who monopolizes the reproduction and regulates the cohesion of the society via pheromones. We therefore analyzed the impact of N. ceranae on queen physiology. We found that infection by N. ceranae did not affect the fat body content (an indicator of energy stores) but did alter the vitellogenin titer (an indicator of fertility and longevity), the total antioxidant capacity and the queen mandibular pheromones, which surprisingly were all significantly increased in Nosema-infected queens. Thus, such physiological changes may impact queen health, leading to changes in pheromone production, that could explain Nosema-induced supersedure (queen replacement). (C) 2010 Elsevier Inc.
