Summary statistics of <i>C. bombi</i> infections in worker and queen bees over two years (summer 2008 – spring 2010).

N is number of hosts. Note that the study aim was to characterize a typical sample from the field. Sample sizes are thus too limited to generate a statistic for every host species separately. aComparing prevalence of mixed-genotype infections (queens vs. workers): χ2 = 1.357, p = 0.244. bComparing number of different genotypes (queens vs. workers): t80 = −1.225, p = 0.224. cComparing number of primary infections (queens vs. workers): t80 = 3.156, p = 0.002.
