The New Higher Level Classification of Eukaryotes with Emphasis on the Taxonomy of Protists
TLDR
This revision of the classification of unicellular eukaryotes updates that of Levine et al. (1980) for the protozoa and expands it to include other protists, and proposes a scheme that is based on nameless ranked systematics. Expand
Phylogenetic relationships among eight Eimeria species infecting domestic fowl inferred using complete small subunit ribosomal DNA sequences.
TLDR
Clades of avian Eimeria species and the apparent absence of coccidia that infect the ceca of jungle fowl all suggest that E. necatrix and E. tenella may have arisen from a host switch, perhaps from the North American turkey, Meleagris gallopavo. Expand
Phylogenetic Position of the Adeleorinid Coccidia (Myzozoa, Apicomplexa, Coccidia, Eucoccidiorida, Adeleorina) Inferred Using 18S rDNA Sequences
TLDR
It is concluded that additional taxon sampling and use of other genetic markers apart from 18S rDNA will be required to better resolve relationships among these parasites and that additional phylogenetic studies of the Adeleorina are needed. Expand
Canine hepatozoonosis: two disease syndromes caused by separate Hepatozoon spp.
TLDR
Comparisons of these related species illustrates that whereas HepatoZoon canis appears to be well adapted to its canine host, Hepatozoon americanum, an emerging pathogen producing severe and frequently fatal myositis, is highly virulent and might have recently crossed the species barrier from a wild host. Expand
DNA barcoding identifies Eimeria species and contributes to the phylogenetics of coccidian parasites (Eimeriorina, Apicomplexa, Alveolata).
TLDR
It is concluded that COI performs well as a marker for the identification of coccidian taxa (Eimeriorina) and will make an excellent DNA 'barcode' target for coccidia. Expand
Cryptosporidium is more closely related to the gregarines than to coccidia as shown by phylogenetic analysis of apicomplexan parasites inferred using small-subunit ribosomal RNA gene sequences
TLDR
The trees indicate that the genus Cryptosporidium has a closer phylogenetic affinity with the gregarines than with the coccidia, and these results do not support the present classification of the cryptosporidiidae in the suborder Eimerioirina Léger, 1911. Expand
Redescription of Neospora caninum and its differentiation from related coccidia.
TLDR
The authors redescribe the parasite, distinguish it from related coccidia, and provide accession numbers to its type specimens deposited in museums. Expand
The Genus Atoxoplasma (Garnham 1950) as a Junior Objective Synonym of the Genus Isospora (Schneider 1881) Species Infecting Birds and Resurrection of Cystoisospora (Frenkel 1977) as the Correct Genus
TLDR
Molecular and morphological data permit a rational subdivision of the paraphyletic Isospora into 2 apparently monophyletic groups of parasites, i.e., Isosporozoic, diplosporocystic oocysts possessing Stieda bodies in their sporocysts and Cystoisospora. Expand
Phylogenetic analysis of the class Sporozoea (phylum Apicomplexa Levine, 1970): evidence for the independent evolution of heteroxenous life cycles.

  • Biology, Medicine
  • The Journal of parasitology
  • 1 April 1989
TLDR
Correlation between parasite phylogeny and taxonomic affinities of their definitive hosts suggests that the definitive hosts of heteroxenous sporozoa are their ancestral hosts. Expand
The conceptual basis for a new classification of the coccidia.
TLDR
The immediate outcome of the Controversial Roundtable on 'New classification of coccidia' recommends the establishment of an international group of scientists to meet on a regular basis to stimulate and encourage discussion and debate on current classification schemes for the group of parasitic protozoa known as the eimeriid coccidi.
