ABSTRACT. Three complete 18S ribosomal RNA gene sequences from the rumen ciliates, Entodinium coudatum (1,639 bp), Epidinium caudarum (1,638 bp), and Polyplastron multivesiculatum (1,640 bp) were determined and confrimed in the opposite direction. Trees produced using maximum parsimony and distance‐matrix methods (lest squares and neighbour‐joining). with strong bootstrap support, depict the rumen ciliates as a monophyletic group, Entodinium caudatum is the earliest branching rumen ciliate… Expand
Monophyly of the Trichostome ciliates (Phylum ciliophora: Class litostomatea) tested using new 18S rRNA sequences from the Vestibuliferids, Isotricha intestinalis and Dasytricha ruminantium, and the Haptorian, Didinium nasutum
TLDR
The monophyly of the trichostomes was tested using new 18S rRNA gene sequences from the rumen ciliates, Dasytricha ruminantium and Isotricha intestinalis, and the haptorian, Didinium nasutum, to form a clade that was the sister group to the pleurostome, Loxophyllum. Expand
Phylogeny of trichostome ciliates (Ciliophora, Litostomatea) endosymbiotic in the Yakut horse (Equus caballus).
TLDR
Based on their morphology, Cycloposthium, Tripalmaria, and Cochliatoxum are classified as Entodiniomorphida, while Paraisotricha is considered a member of the Vestibuliferida, andylogenetic analyses using Bayesian inference, distance, and parsimony methods confirm these placements. Expand
Phylogenetic analysis of the rumen ciliate family Ophryoscolecidae based on 18S ribosomal RNA sequences, with new sequences from Diplodinium, Eudiplodinium, and Ophryoscolex
TLDR
The cladistic analysis, based on the limited morphological and ultrastructural data available, indicates that there are no synapomorphies supporting the Diplodiniinae sensu Lubinsky and the rumen ciliates are monophyletic. Expand
Phylogenetic Relationships of the Subclass Peritrichia (Oligohymenophorea, Ciliophora) Inferred from Small Subunit rRNA Gene Sequences1
TLDR
The phylogenetic relationships among peritrichs remain unresolved and trees were constructed using distance-matrix, maximum-likelihood and maximum-parsimony methods, all of which strongly supported the monophyly of the subclass Peritrichia. Expand
An expanded phylogeny of the Entodiniomorphida (Ciliophora : Litostomatea)
TLDR
There is more evolutionary distance between the Cycloposthiidae and Ophryoscolecidae than previously inferred from studies of gross morphology, cell ontogeny or ultrastructure, and the currently accepted classification of the Trichostomatia is thus deficient and in need of review. Expand
Phylogeny and classification of the Litostomatea (Protista, Ciliophora), with emphasis on free-living taxa and the 18S rRNA gene.
TLDR
The phylogenetic analyses and some strong morphological traits show body polarization and simplification of the oral apparatus as main evolutionary trends in the Litostomatea and three distinct lineages (subclasses) of the Haptoria and Trichostomatia. Expand
Molecular phylogeny of litostome ciliates (Ciliophora, Litostomatea) with emphasis on free-living haptorian genera.
TLDR
The monophyly of the litostomes was tested using nine newly sequenced and four previously unpublished small subunit ribosomal RNA (SSrRNA) gene sequences from free-living Haptoria as well as from endosymbiotic Trichostomatia to distinguish three clades: an Australian clade; the order Entodiniomorphida; and the order Vestibuliferida. Expand
Phylogeny and classification of the Litostomatea ( Protista , Ciliophora ) , with emphasis on free-living taxa and the 18 S rRNA gene
The class Litostomatea is a highly diverse ciliate taxon comprising hundreds of species ranging from aerobic, free-living predators to anaerobic endocommensals. This is traditionally reflected byExpand
Phylogenetic Relationships of the Subclass Peniculia (Oligohymenophorea, Ciliophora) Inferred from Small Subunit rRNA Gene Sequences
TLDR
It is concluded that the Subclass Peniculia should be divided into two orders, the Order Urocentrida and Order Peniculida, with the latter order having two suborders, the Suborder Frontoniina and PenicULina. Expand
Phylogenetic position of the ciliates Phacodinium (Order Phacodiniida) and Protocruzia (Subclass Protocruziidia) and systematics of the spirotrich ciliates examined by small subunit ribosomal RNA gene sequences
TLDR
Halteria groups within the stichotrich clade, supporting the argument that the oligotrichs are not monophyletic as currently conceived, and Phacodinium branches after Euplotes at a deep level, confirming the conclusion that others have reached that this genus is related to the hypotrich and stichOTrich spirotrichs.

Evolution of 16S-like ribosomal RNA genes in the ciliophoran taxa litostomatea and phyllopharyngea
TLDR
Using the rRNA phylogenies as framework to understand the evolution of non-molecular features, the low complexity of their oral structures can be interpreted as a secondary adaptation — possibly caused by a shift towards macro-phagous feeding behavior. Expand
Ribosomal RNA sequences of Sarcocystis muris, Theileria annulata and Crypthecodinium cohnii reveal evolutionary relationships among apicomplexans, dinoflagellates, and ciliates.
TLDR
Evolutionary trees inferred from the rRNA sequence similarities support a close phylogenetic relationship between the Apicomplexa and Dinoflagellata as represented by Prorocentrum micans and C. cohnii. Expand
Phylogenetic Relationships of the Nassulida Within the Phylum Ciliophora Inferred from the Complete Small Subunit rRNA Gene Sequences of Furgasonia blochmanni, Obertrumia georgiana, and Pseudomicrothorax dubius
ABSTRACT. Using comparisons of complete small subunit rRNA sequences from the ciliated protozoans Furgasonia blochmanni, Obertrumia georgiana, and Pseudomicrothorax dubius we inferred theExpand
Phylogeny and evolution of the piroplasms.
TLDR
The parsimony and maximum likelihood trees suggest that the babesias and theilerias are sister taxa, both of which were derived from the paraphyletic group. Expand
Insights into the Evolution of Nuclear Dualism in the Ciliates Revealed by Phylogenetic Analysis of rRNA Sequences
TLDR
The distribution of nuclear division types along the phylogenetic tree is consistent with the notion that macronuclei incapable of division represent a derived rather than a primitive or “karyorelictid” character trait. Expand
Phylogeny of the fish parasite Ichthyophthirius and its relatives Ophryoglena and Tetrahymena (Ciliophora, Hymenostomatia) inferred from 18S ribosomal RNA sequences.
TLDR
Phylogenetic relationships within the subclass Hymenostomatia were inferred from the comparisons of three new SSrRNA gene sequences from Ichthyophthirius multifiliis, Ophryoglena catenula, and Tetrahymena corlissi, consistent with their placement in theOphryoglenina. Expand
Phylogenetic relationships among karyorelictids and heterotrichs inferred from small subunit rRNA sequences: resolution at the base of the ciliate tree.
TLDR
It is indicated, with strong support, that the aerobic heterotrichs and the karyorelictids sampled constitute a monophyletic group, and the complex mouth architecture which characterizes all heterot richs must be reassessed in light of this finding. Expand
The Phylogeny of the Stomach-Infusorians of Ruminants in the Light of palaeontological and parasitological Data
TLDR
It is concluded that the genera of Ophryoscolecidae arose at different periods, the more complicated ones appearing later than the simpler, and the need for a study of the yet unknown Infusorian fauna of Lama, and especially of Giraffidae, is emphasized. Expand

TLDR
Mating experiments demonstrated that these "mosquito" ciliates were reproductively isolated from previously described biological species in the complex, and are designated a new species, Tetrahymena empidokyrea n.sp. Expand
The functional and evolutionary significance of the ultrastructure of the Ophryoscolecidae (order Entodiniomorphida)
TLDR
The original evolutionary lineage of ophryoscolecid ciliates based on morphological studies using light microscopy is supported by observations of ultrastructural variations in the cytopharynx and in their relationship with diet via possible ingestion mechanisms. Expand
