Characterization of new cristamonad species from kalotermitid termites including a novel genus, Runanympha

Cristamonadea is a large class of parabasalian protists that reside of lignocellulose. This group of symbionts boasts an impressive array of complex morphological species of cristamonad symbionts from Comatermes, Calcariter...

Pseudotrichonympha leei, Pseudotrichonympha lifesoni, and Pseudotrichonympha pearti, new species of parabasalian flagellates and the description of a rotating subcellular structure

Pseudotrichonympha is a large and structurally complex genus of parabasalian. Like many termite symbionts, it has a conspicuous body plan that makes genus-level and phylogenetic position of each symbiont, all three represen...

Morphology and Molecular Phylogeny of Pseudotrichonympha hertwigi and Pseudotrichonympha paulistana (Trichonymphea, Parabasalia) from Neotropical Rhinotermitids

Pseudotrichonympha is a large hypermastigote parabasalian found in the hindgut of several species of rhinotermitid termites. The genus was discovered more than 100 years ago, and although over a dozen species have since been described Pseudo...

Critical analysis of the topology and rooting of the parabasalian 16S rRNA tree

We discuss the tree topology in the view of anagenesis of cytoskeletal and motility organelles and suggest that a robust taxonomic revision requires extensive analysis of other gene sequences....

Genotype specificity among hosts, pathogens, and beneficial microbes influences the strength of symbiont-mediated protection

The microbial symbionts of eukaryotes influence disease resistance in many host-parasite systems. Symbionts show substantial variation in both genotype and phenotype variable symbiont genotypes show specificity with the gen...
