| the comparison of rdna spacer regions of nosema ceranae isolates from different hosts and locations. | 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. mellifer ... | 2008 | 17709115 |
