A guideline for the preparation of species descriptions in the Eimeriidae.
TLDR
This work proposes a specific set of guidelines for the preparation of species descriptions of coccidia based predominently on the structure of the sporulated oocyst, and emphasizes that ancillary data be incorporated whenever possible with the species description. 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. Expand
A simple method of DNA extraction for Eimeria species.
TLDR
A new, simple method is described for extracting DNA from coccidia (Eimeriidae) oocysts that greatly simplifies the currently used DNA extraction procedures for Eimeria species and overcomes the disadvantages of existing DNA extraction methods based on glass-bead grinding and sporozoite excystation procedures.

COCCIDIOSIS OF SANDHILL CRANES (GRUS CANADENSIS) WINTERING IN NEW MEXICO
The feces of 212 sandhill cranes (Grus canadensis) collected in central New Mexico from October 1982 to January 1983 and from October 1983 to January 1984 were examined to determine the prevalence of… Expand
Four New Cestode Species from the Spiral Intestine of the Round Stingray, Urobatis halleri, in the Northern Gulf of California, Mexico
TLDR
The spiral intestines of 40 specimens of Urobatis halleri from the northern Gulf of California, Mexico, were examined for cestodes and four new species are described, the first record of these 3 genera in the Gulf ofCalifornia and the first report of Eutetrarhynchus in U. halleri. Expand
Phylogenetic relationships among rodent Eimeria species determined by plastid ORF470 and nuclear 18S rDNA sequences.
TLDR
The oocyst residuum was the most determinant feature that differentiated the two lineages of rodent Eimeria species, which reflect more their morphological differences than host specificity. Expand
PHYLOGENETIC POSITION OF EIMERIA ANTROZOI, A BAT COCCIDIUM (APICOMPLEXA: EIMERIIDAE) AND ITS RELATIONSHIP TO MORPHOLOGICALLY SIMILAR EIMERIA SPP. FROM BATS AND RODENTS BASED ON NUCLEAR 18S AND…
TLDR
The phylogenies based onplastid 23S rDNA data and combined data of both plastid and nuclear genes grouped 2 bat Eimeria and 3 morphologically similar Eimaria species from rodents into 2 separate clades with high bootstrap support, which supports E. antrozoi as a valid species. Expand
Molecular phylogenies suggest the oocyst residuum can be used to distinguish two independent lineages of Eimeria spp in rodents
TLDR
Examination of the morphological features of all 16 Eimeria species indicates that only the oocyst residuum shows a clear correlation to the phylogenetic relationships determined by the molecular data, and it seems likely that the two EIMeria lineages split before their host families diverged.

Coccidia (Apicomplexa: Eimeriidea) of the Mammalian Order Insectivora
TLDR
This review focuses on those species within the Eimeriidae because they are among the most prevalent and speciose of all parasite groups, and there is no taxonomic summation currently available for those species that infect insectivores. Expand
