| an integrated morphological and molecular approach to a new species description in the trypanosomatidae: the case of leptomonas podlipaevi n. sp., a parasite of boisea rubrolineata (hemiptera: rhopalidae). | leptomonas podlipaevi n. sp., a new trypanosomatid species, is described herein based on light microscopic, ultrastructural, and molecular phylogenetic data. the organism is pleomorphic both in host and culture, with two predominant forms-a typical promastigote with a long flagellum and a shorter promastigote with a small or barely extending flagellum. several spliced leader rna repeat sequences obtained from the original cultures and the clonal lines representing two types of cells were all nea ... | 2006 | 16579812 |
| lineage-specific activities of a multipotent mitochondrion of trypanosomatid flagellates. | trypanosomatids are a very diverse group composed of monoxenous and dixenous parasites belonging to the excavate class kinetoplastea. here we studied the respiration of five monoxenous species (blechomonas ayalai, herpetomonas muscarum, h. samuelpessoai, leptomonas pyrrhocoris and sergeia podlipaevi) introduced into culture, each representing a novel yet globally distributed and/or species-rich clade, and compare them with well-studied flagellates trypanosoma brucei, phytomonas serpens, crithidi ... | 2015 | 25557487 |
| genome of leptomonas pyrrhocoris: a high-quality reference for monoxenous trypanosomatids and new insights into evolution of leishmania. | many high-quality genomes are available for dixenous (two hosts) trypanosomatid species of the genera trypanosoma, leishmania, and phytomonas, but only fragmentary information is available for monoxenous (single-host) trypanosomatids. in trypanosomatids, monoxeny is ancestral to dixeny, thus it is anticipated that the genome sequences of the key monoxenous parasites will be instrumental for both understanding the origin of parasitism and the evolution of dixeny. here, we present a high-quality g ... | 2016 | 27021793 |
| symbiont transmission entails the risk of parasite infection. | like many animals, firebugs (hemiptera, pyrrhocoridae) rely on behavioural adaptations to successfully endow their offspring with microbial mutualists. to transmit the nutritionally beneficial coriobacteriaceae symbionts, female firebugs smear egg surfaces with symbiont-containing faecal droplets that are subsequently ingested by newly hatched nymphs through active probing to initiate infection. alternatively, the symbionts can be acquired horizontally through contact with faeces of infected con ... | 2015 | 26673937 |
| cosmopolitan distribution of a trypanosomatid leptomonas pyrrhocoris. | a trypanosomatid species, designated as typing unit 1 (tu1) by sequences of sl rna gene repeats, has been found in the intestine of pyrrhocorids (insecta: heteroptera) in europe, mediterranean, central america and some parts of asia and africa. phylogenetic analysis of the sl repeat sequences has shown that the isolates group in the tree according to their geographic origin. the maximal sequence divergence was observed in parasites from neotropics suggesting the origin within and subsequent migr ... | 2012 | 22341645 |
