CBOL Protist Working Group: Barcoding Eukaryotic Richness beyond the Animal, Plant, and Fungal Kingdoms
A group of protist experts proposes a two-step DNA barcoding approach, comprising a universal eukaryotic pre-barcode followed by group-specific barcodes, to unveil the hidden biodiversity of
Cryptosporidia: epicellular parasites embraced by the host cell membrane.
TLDR
Observations presented herein allowed us to map ultrastructural aspects of the cryptosporidian invasion process and the origin of a parasitophorous sac, providing a new insight into the ultrastructureural detail of host-parasite interactions and species-specific differences manifested in frequency of detachment of the parasitophile sac.
Molecular Phylogenetic Relatedness of Frenkelia spp. (Protozoa, Apicomplexa) to Sarcocystis falcatula Stiles 1893: Is the Genus Sarcocystis Paraphyletic?
TLDR
The inclusion of the small subunit ribosomal RNA gene sequences of both Frenkelia species into the SSU rRNA trees of other, tissue cyst‐forming coccidia strongly supports paraphyly of the genus Sarcocystis.
On the phylogenetic positions of the Caryophyllidea, Pseudophyllidea and Proteocephalidea (Eucestoda) inferred from 18S rRNA.
A phylogenetic analysis of tapeworms (Eucestoda) based on complete sequences of the 18S rRNA genes of 43 taxa (including new sequences of 12 species) was carried out, with the emphasis on the groups
New species of Cryptosporidium Tyzzer, 1907 (Apicomplexa) from amphibian host: morphology, biology and phylogeny.
TLDR
The experience with the description of C. fragile has led to revise the recommended criteria for an introduction of a new Cryptosporidium species name, and its prevalence of 83% in black-spined toads within the 3 months after importation calls for strict quarantine measures and import regulation for lower vertebrates.
A Suspected Parasite Spill-Back of Two Novel Myxidium spp. (Myxosporea) Causing Disease in Australian Endemic Frogs Found in the Invasive Cane Toad
Infectious diseases are contributing to the decline of endangered amphibians. We identified myxosporean parasites, Myxidium spp. (Myxosporea: Myxozoa), in the brain and liver of declining native
Three new species of coccidia (Apicomplexa: Eimeriorina) from the Marble-throated skink, Marmorosphax tricolor Bavay, 1869 (Reptilia: Scincidae), endemic to New Caledonia with a taxonomic revision of
Three new species of coccidia are described from Marble-throated skink Marmorosphax tricolor from New Caledonia, namely, Isospora bocagei sp. n., Acroeimeria rouxi sp. n., and Choleoeimeria sadlieri
Goussia Labbé, 1896 (Apicomplexa, Eimeriorina) in Amphibia: diversity, biology, molecular phylogeny and comments on the status of the genus.
TLDR
Molecular phylogenetic analysis showed that anuran-host Goussia form a well-supported monophyletic clade, which together with a clade represented by piscine G Moussia metchnikovi, constitute basal lineages of the Eimeriidae.
Phylogenetic position of a renal coccidium of the European green frogs, 'Isospora' lieberkuehni Labbé, 1894 (Apicomplexa: Sarcocystidae) and its taxonomic implications.
'Isospora' lieberkuehni, an unusual isosporoid renal coccidium that parasitizes the European water frog was isolated from the edible frog, Rana kl. esculenta, in the Czech Republic. Sequencing of the
Bothriocephalidean tapeworms (Cestoda) of freshwater fish in Africa, including erection of Kirstenella n. gen. and description of Tetracampos martinae n. sp.
TLDR
A survey of bothriocephalidean tapeworms (Cestoda) parasitizing African freshwater fish is provided and a new genus is proposed, distinguished from other genera of the Bothriocephalidae by the presence of an apical disc armed with two lateral semicircles of large hooks, cortical vitelline follicles and large-sizedcirrus-sac.
