| phylogenetic relationships of pleistophora-like microsporidia based on small subunit ribosomal dna sequences and implications for the source of trachipleistophora hominis infections. | the microsporidian trachipleistophora hominis was isolated in vitro from the skeletal muscle of an aids patient. since its discovery several more cases of myositis due to trachipleistophora have been diagnosed but the source of infection is unknown. morphologically, t. hominis most closely resembles pleistophora and vavraia, which undergo polysporous sporogony in sporophorous vesicles, but differs from these genera in the mode of formation of sporoblasts and in the morphology of the sporophorous ... | 2000 | 10847345 |
| relationships of microsporidian genera, with emphasis on the polysporous genera, revealed by sequences of the largest subunit of rna polymerase ii (rpb1). | molecular data have proved useful as an alternative to morphological data in showing the relationships of genera within the phylum microsporidia, but until now have been available only for ribosomal genes. in previous studies protein-coding genes of microsporidia have been used only to assess their position in the evolution of eukaryotes. for the first time we report on the use of a protein-coding gene, the a-g region of the largest subunit of rna polymerase ii (rpb1) from 14 mainly polysporous ... | 2001 | 11249186 |
| ultrastructure and molecular phylogenetics of a new isolate of pleistophora pagri sp. nov. (microsporidia, pleistophoridae) from pagrus pagrus in egypt. | the spore morphology and molecular systematic of a new microsporidian which was isolated from the common sea bream pagrus pagrus (f: sparidae linnaeus, 1758) from the red sea, egypt have been studied. fifty-six out of 300 (18.7%) of this fish were infected with microsporidian parasites. the infection was appeared as whitish, ellipsoid, round, or elongated nodules embedded in the epithelial lining of the peritoneum and also in the intestinal epithelium. light microscopic study revealed that nodul ... | 2012 | 22773009 |
