| in vitro culture and phylogenetic analysis of "candidatus arsenophonus triatominarum," an intracellular bacterium from the triatomine bug, triatoma infestans. | an intracellular symbiotic bacterium was isolated from the hemolymph of triatoma infestans and cultured in an aedes albopictus cell line. 16s ribosomal dna sequence analysis revealed that the bacterium was a member of the gamma-3 subgroup of the class proteobacteria, having 96.2% sequence identity with the most closely related bacterium, arsenophonus nasoniae, the causative agent of the son-killer trait in the parasitoid wasp nasonia vitripennis. these bacteria share morphological features and a ... | 1997 | 9336921 |
| an effect of 16s rrna intercistronic variability on coevolutionary analysis in symbiotic bacteria: molecular phylogeny of arsenophonus triatominarum. | the genes of ribosomal rna are the most popular and frequently used markers for bacterial phylogeny and reconstruction of insect-symbiont coevolution. in primary symbionts, such as buchnera and wigglesworthia, genome economization leads to the establishment of a single copy of these sequences. in phylogenetic studies, they provide sufficient information and yield phylogenetic trees congruent with host evolution. in contrast, other symbiotic lineages (e.g., the genus arsenophonus) carry a higher ... | 2008 | 18485654 |
