I already mentioned the observation that an enriched diet may increase nosema spore count. This is further confirmed by this work, just completed:

> In this study, I examined effects of different concentrations of pollen on the prevalence and intensity of Nosema ceranae as well as the longevity and nutritional physiology of infected bees. Significantly higher spore intensities were observed in treatments that received higher pollen concentrations when compared to treatments that received relatively lower pollen concentrations. Interestingly, the bees in higher pollen concentration treatments also had significantly higher survival despite higher intensities of Nosema ceranae.
