abstract：:Nosema ceranae is currently one of the major pathogens of honeybees, related to the worldwide colony losses phenomenon. The genotyping of strains based on ribosomal DNA (rDNA) can be misleading if the repeated units are not identical. The analysis of cloned rDNA fragments containing the intergenic spacer (IGS) and par...
