| phylogenetic analysis of nosema antheraeae (microsporidia) isolated from chinese oak silkworm, antheraea pernyi. | the microsporidian nosema antheraeae is a pathogen that infects the chinese oak silkworm, antheraea pernyi. we sequenced the complete small subunit (ssu) rrna gene and the internal transcribed spacer (its) of n. antheraeae, and compared the ssu rrna sequences in other microsporidia. the results indicated that nosema species, including n. antheraeae, formed two distinct clades, consistent with previous observations. furthermore, n. antheraeae is clustered with n. bombycis with high bootstrap supp ... | 2006 | 16872300 |
| morphological and molecular studies of a microsporidium (nosema sp.) isolated from the thee spot grass yellow butterfly, eurema blanda arsakia (lepidoptera: pieridae). | a microsporidium possessing molecular and morphological characteristics of the genus nosema was isolated from larvae of the thee-spot grass yellow butterfly, eurema blanda arsakia. the complete rrna gene sequences of the e. blanda isolate contained 4,428 base pairs (genbank accession no. eu338534). the organization of the rrna genes is lsu rrna-its-ssu rrna-igs-5s, which corresponds with that of nosema species closely related to nosema bombycis. phylogenetic analysis based on rrna gene sequences ... | 2009 | 19041874 |
| the nuclear apparatus and chromosomal dna of the microsporidian nosema antheraeae. | the microsporidian nosema antheraeae is a pathogen of the chinese oak silkmoth antheraea pernyi, the molecular karyotype of which is still poorly understood. here the diplokaryon of n. antheraeae strain np-yy has been visualized both by fluorescence and electron microscopy. in addition, pulsed-field gel electrophoresis (pfge) showed that the haploid genome of n. antheraeae is approximately 9.3-9.5 million base pairs organized into 15 chromosomal bands. the mean fluorescence intensity of n. anthe ... | 2011 | 21382124 |
| morphological and molecular characterization of nosema pernyi, a microsporidian parasite in antheraea pernyi. | nosema pernyi is a lethal pathogen that causes microsporidiosis in the chinese oak silkworm, antheraea pernyi. in this study, we presented its morphological and some molecular characteristics. the mature spores were measured to be 4.36 × 1.49 μm. the spore wall consisted of an electron-dense exospore (ex) and electron-lucent endospore (en) layer. the polar filament (pf) was isofilar with 10-12 coils that were frequently arranged in a single row. investigation results indicated that n. pernyi can ... | 2015 | 26044882 |
| identification, diversity and evolution of mites in the genomes of microsporidian nosema parasites. | miniature inverted-repeat transposable elements (mites) are short, non-autonomous dna transposons, which are widespread in most eukaryotic genomes. however, genome-wide identification, origin and evolution of mites remain largely obscure in microsporidia. in this study, we investigated structural features for de novo identification of mites in genomes of silkworm microsporidia nosema bombycis and nosema antheraeae, as well as a honeybee microsporidia nosema ceranae. a total of 1490, 149 and 83 m ... | 2015 | 25898273 |
