ABSTRACT. The rRNA gene cluster of microsporidia is typically arranged in the order small subunit‐internal transcribed spacer‐large subunit, which conforms with the general arrangement of these genes in nearly all organisms. We found a rearrangement of the cluster in the microsporidium Glugoides intestinalis, where the large subunit precedes the small subunit. Such a rearrangement has already been reported for several species in the microsporidian genus Nosema, and we provide evidence that the arrangement reported here is a second, independent event.
