蜜蜂的喉咽腺分泌幼虫食物皇家浆，沿着酶，酶用于从花蜜生产蜂蜜。这种分泌物混合物的组成随蜜蜂的生理条件而变化，最终的分泌物混合物通过胞外导管输送到大的排泄管。用透射电镜和图像分析技术对健康和感染蜜蜂的胞外导管分泌物进行了研究。这些产品由密集的、隐约可见的颗粒状物质组成。通过计算机增强图像清楚地限定颗粒。微孢子虫感染蜜蜂的分泌物具有相同的颗粒结构，但浓度低得多，从而降低了分泌物的总体电子密度。这些观察结果表明，分泌物的组成从下咽腺在微孢子虫感染的蜜蜂，发生了很大的变化。
The hypopharyngeal glands of the honeybee secrete the larval food royal jelly, along with enzymes that are used in the production of honey from nectar. The composition of this secretion mixture varies with the physiological condition of the honeybee, and the final secretion mixture is conveyed through the extracellular ducts to the large excretory duct. The secretion products in the extracellular duct of both healthy and infected honeybees, was studied by transmission electron microscopy and image analysis. These products consisted of a densely packed, faintly visible granular substance. The granules were clearly defined by the computer enhanced image. The secretion products from the Nosema-infected honeybees exhibited the same granular structure, but were much less concentrated, thereby reducing the overall electron density of the secretion. These observations suggest that the composition of the secretion products from the hypopharyngeal glands in the Nosema-infected honeybees, was altered considerably.
