When I sat my microscopy exam a few years ago, you are expected to take some live bees, from which to make a slide for Nosema examination. It was full of Nosema spores. The examiner ( Graham Royle) asked if I had expected that as it was the heaviest infestation he has seen for a long time. He in fact asked for a sample so that he could use it for teaching purposes. I replied it was totally enexpected as the bees appeared strong and healthy. He suggested I could spray the thymol recipe over each comb, but I was likely to lose the colony, but As it was later in the year I did not do so. I had plenty of other colonies. The bees came through the winter OK, still strong, and when sampled in spring the Nosema count was very low. I do not know what was going on but the bees obviously handled it themselves.
