A molecular approach to the tangled intrageneric relationships underlying phylogeny in Euplotes (Ciliophora, Spirotrichea).
The cosmopolitan genus Euplotes is remarkable among ciliates for its species richness. To understand the still tangled taxonomy and phylogenetic relationships within the genus, small subunit rRNA… Expand

Defensive extrusive ectosymbionts of Euplotidium (Ciliophora) that contain microtubule-like structures are bacteria related to Verrucomicrobia.
Epixenosomes, ectosymbionts on hypotrich ciliates (genus Euplotidium) defend their host against the ciliate predator Litonotus lamella. Although here only Euplotidium itoi and Euplotidium arenarium… Expand

Focusing on genera to improve species identification: revised systematics of the ciliate Spirostomum.
Although many papers dealing with the description of new ciliate taxa are published each year, species taxonomy and identification in most groups of the phylum Ciliophora remain confused. This is… Expand

A Multidisciplinary Approach to Describe Protists: a Morphological, Ultrastructural, and Molecular Study on Peritromus kahli Villeneuve-Brachon, 1940 (Ciliophora, Heterotrichea)
Abstract This study represents the first extended report on a species of the ciliate genus Peritromus, widespread in marine biotopes, characterized by a dorso-ventral differentiation peculiar among… Expand

Resting cysts: A survival strategy in Protozoa Ciliophora
Abstract Encystment is a reversible cell differentiation process that also requires an antagonistic process, i.e. excystment. Both processes are genetically encoded. Encystment is of common… Expand

Molecular phylogeny of unculturable Karyorelictea (Alveolata, Ciliophora)
Karyorelictea is a class of traditionally unculturable ciliates characterized by a non‐dividing macronucleus. Their classification has been recently revised and morphological redescription of many… Expand

Molecular systematics and ultrastructural characterization of a forgotten species: Chattonidium setense (Ciliophora, Heterotrichea)
In the present paper we redescribe the ciliate Chattonidium setense Villeneuve 1937 combining morphological observations (live, stained, scanning, and transmission electron microscope) with… Expand

Polynucleobacter Bacteria in the Brackish‐Water Species Euplotes harpa (Ciliata Hypotrichia)
Abstract. We have found a Polynucleobacter bacterium in the cytoplasm of Euplotes harpa, a species living in a brackish‐water habitat, with a cirral pattern not corresponding to that of the… Expand

Identification of the bacterial endosymbionts of the marine ciliate Euplotes magnicirratus (Ciliophora, Hypotrichia) and proposal of 'Candidatus Devosia euplotis'.
This paper reports the identification of bacterial endosymbionts that inhabit the cytoplasm of the marine ciliated protozoon Euplotes magnicirratus. Ultrastructural and full-cycle rRNA approaches… Expand

‘Candidatus Megaira polyxenophila’ gen. nov., sp. nov.: Considerations on Evolutionary History, Host Range and Shift of Early Divergent Rickettsiae
“Neglected Rickettsiaceae” (i.e. those harboured by non-hematophagous eukaryotic hosts) display greater phylogenetic variability and more widespread dispersal than pathogenic ones; yet, the knowledge… Expand
