Abstract
Nosema ceranae is a common microsporidian pathogen, one of two Nosema species that cause "nosema disease" in honeybees, Apis cerana and Apis mellifera. Samples of N. ceranae rDNA from isolates collected in different locations were sequenced and one 5S rRNA was found to be upstream of SSUrRNA. The rDNA arrangement, 5'-5S rRNA-IGS-SSUrRNA-ITS-LSUrRNA-3', was found in all isolates. In order to better understand the distribution relationship between N. ceranae isolates from A. cerana and A. mellifera, their rRNA spacer regions were also sequenced for analysis. Results showed that there are no significant differences between the IGS sequences of the isolates and no difference in the ITS sequence with the exception of one transition found in an isolate from Martinique. These isolates showed consistency in the IGS phylogenic analysis suggesting that no transmission barrier exists between A. mellifera and A. cerana and there is no difference between isolates from geography separated areas.Entities:
