This experiment studied the parasitic degree in Poecilia vivipara experimentally infected by Ichthyophthirius multifiliis trophozoites. In flasks with 400 mL of water, four fish were maintained with constant aeration in two replicates and added 0, 1, 2, 4, 8, 16 and 20 trophozoites/fish. Mean values of water temperature, pH and dissolved oxygen were 19.

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

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 ...
