An unknown parasitic protist is described in the free-living cryptophyte Chilomonas paramaecium. The biflagellated sporozoite has an elongated shape with an apical complex and a central nucleus. The pair of flagella are inserted at the base of the pseudo-conoid, and two microtubular roots situated underneath the plasma membrane are attached to each basal body. The apical complex comprises a set of 10-14 micronemes and a train of dumb-bell vesicles which converge toward the tip of the pseudo… 
Colpodella vorax: ultrastructure, predation, life-cycle, mitosis, and phylogenetic relationships
TLDR
The flagellar apparatus of Colpodella vorax comprises two widely separated basal bodies/flagella linked by a pluri-lamellar connector, very short basal bodies and a slightly longer transitional zone, and the pseudo-conoid transforms into a ring of microtubules encircling the attachment zone.
ife-cycle , ultrastructure , and phylogeny of Parvilucifera corolla sp . nov . Alveolata , Perkinsozoa ) , a parasitoid of dino fl agellates
TLDR
New species of the parasitoid genus Parvilucifera is described that was observed infecting the dinoflagellate Durinskia baltica in salt arshes of the Catalan coast and detected after the incubation of seawater rom the Canary Islands.
orphology and Ultrastructure of Multiple Life ycle Stages of the Photosynthetic Relative of picomplexa , Chromera velia
TLDR
Ulastructural analysis of coccoid cells of C. velia and previously undocumented bi-flagellated stage supports its close association with colpodellids and apicomplexans and provides insight into their evolution.

An intracellular parasite occurring inCryptomonas rostratiformis and less numerously also inC. erosa andC. phaseolus. The parasite is described. It grows in the dorsal side of the host near the
Ultrastructure and identification of the predatory flagellateColpodella pugnax Cienkowski (Apicomplexa) with a description ofColpodella turpis n. sp. and a review of the genus
TLDR
It is confirmed that Colpodella is the genus with free-living species most closely related to the apicomplexan parasites (i.e. the “Euapicom Complexa” and “Perkinsus”), and no unambiguous synapomorphy supports an “apicOMplexan parasite” clade.
Zoospores of the Oyster Pathogen, Dermocystidium marinum. I. Fine Structure of the Conoid and Other Sporozoan-Like Organelles
TLDR
An apical complex comparable to that found in the Sporozoa is described from zoospores of Dermocystidium marlnum Mackin, Owen, and Collier, a pathogen of the American oyster and believed to contain lytic enzymes which aid the organism in host cell penetration.
First record of an ectoparasitic flagellate on ciliates: an ultrastructural investigation of the morphology and the mode of attachment of Spiromonas gonderi nov. spec. (Zoomastigophora, Spiromonadidae) invading the pellicle of ciliates of the genus Colpoda (Ciliophora, Colpodidae)
TLDR
A flagellate ectoparasitic on ciliates occurred spontaneously in a soil sample, and its fine structure and mode of life show that it is related to the genus Spiromonas, and fine structural peculiarities suggest a close affinity of Spiromonasto the Sporozoa.
