The genus Perkinsus includes protistan parasites infecting marine molluscs throughout the
world, some of which are associated with mass mortalities. Life cycle involves vegetative …

Apicomplexan parasites cause severe diseases such as malaria, toxoplasmosis, and
coccidiosis (caused by Plasmodium spp., Toxoplasma, and Eimeria, respectively). These …

The phylum Apicomplexa encompasses a large number of intracellular protozoan parasites,
including the causative agents of malaria (Plasmodium), toxoplasmosis (Toxoplasma), and …

We have sequenced small-subunit (SSU) ribosomal RNA (rRNA) genes from 16
dinoflagellates, produced phylogenetic trees of the group containing 105 taxa, and …

Oxyrrhis marina and Perkinsus marinus are two alveolate species of key taxonomic position
with respect to the divergence of apicomplexans and dinoflagellates. New sequences from …

Gregarines are thought to be deep-branching apicomplexans. Accordingly, a robust
inference of gregarine phylogeny is crucial to any interpretation of apicomplexan evolution …

The protozoan infrakingdom Alveolata comprises the phyla Ciliophora and Miozoa. The
name Myzozoa—sucking life—is introduced here to replace Miozoa (protalveolates …

The toxic dinoflagellate Dinophysis, collected on the Swedish West Coast, was found to
contain round bodies previously interpreted as the result of sexual reproduction. After two …

Three closely related groups of unicellular organisms (ciliates, dinoflagellates and
apicomplexans) have adopted what might be the most dissimilar modes of eukaryotic life on …

Morphological characters of zoosporulation stages and DNA sequence of the internal
transcribed spacer (ITS) region and the small subunit ribosomal RNA (SSU rRNA) gene …
