Euplotespora binucleata n. gen., n. sp. (Protozoa: Microsporidia), a Parasite Infecting the Hypotrichous Ciliate Euplotes woodruffi, with Observations on Microsporidian Infections in Ciliophora [PDF]

open access: yesJournal of Eukaryotic Microbiology, 2008
ABSTRACT. A new microsporidian species, Euplotespora binucleata n. gen., n. sp., from the brackish‐water ciliate Euplotes woodruffi is described and defined on the basis of life history characteristics, light and electron microscopic features, and small subunit (SSU) ribosomal DNA (rDNA) sequencing. The life cycle of E. binucleata n. sp.

Trichodinid (Ciliophora: Trichodinidae) Infections in Perch (Perca fluviatilis) Experimentally Exposed to Pulp and Paper Mill Effluents [PDF]

open access: yesArchives of Environmental Contamination and Toxicology, 2011
Wild-caught European perch (Perca fluviatilis) were exposed in the laboratory to untreated bleached pulp and paper mill effluent in two separate experiments. The first experiment was conducted at 7-8°C using effluent concentrations of 5 and 10%, and the second experiment was conducted at ambient river temperature of 4-20°C using an effluent ...

Evidence of multiple species of Chilodonella (Protozoa, Ciliophora) infecting Australian farmed freshwater fishes

Veterinary Parasitology, 2017
Parasitic Chilodonella species, Chilodonella piscicola and Chilodonella hexasticha, cause considerable economic losses globally to freshwater farmed fish production. Some genetic studies of Chilodonella spp. have indicated that many species within the genus may form cryptic species complexes. To understand the diversity of Chilodonella spp.

Infection of Aedes albopictus (Diptera: Culicidae) and Ae. aegypti with Lambornella stegomyiae (Ciliophora: Tetrahymenidae)

Journal of Invertebrate Pathology, 1995
The transformation of Lambornella stegomyiae trophonts to theronts, the distribution of invasion cysts on larval Aedes albopictus cuticle, and the virulence of L. stegomyiae to Ae. albopictus and Aedes aegypti were studied in the laboratory. Transformation of trophonts into theronts was induced by a morphogenic agent released from larval Ae. albopictus

Experimental analysis of the resistance of Paramecium caudatum (ciliophora) against infection by bacterium Holospora undulata

European Journal of Protistology, 1997
Summary In some clones of Paramecium caudatum (to be referred to as “resistant”) infectious forms of Holospora undulata bacteria which are capable of infecting the micronucleus were lysed within 3–4 h after invasion of the micronucleus. After microsurgical transplantation of the micronucleus of non-resistant into resistant paramecia (without ...

Extracellular Calcium Concentration Affects Infectivity of Ichthyophthirius (Ciliophora) Theronts

The Journal of Protozoology, 1991
Tomonts and their theront offspring of the hymenostomatid fish parasite Ichthyophthirius multifiliis were exposed to calcium levels from 0 to 0.8 mM Ca2+. The survival and reproductive rates of tomonts in the absence of extracellular calcium were not significantly different from rates of tomonts provided calcium.
