Arsenate toxicity and stress responses in the freshwater ciliate Tetrahymena pyriformis.
The arsenic metabolism in different biological organisms has been studied extensively. However, little is known about protozoa. Herein, we investigated the cell stress responses of the freshwater ciliate Tetrahymena pyriformis to arsenate toxicity. An acute toxicity assay revealed an 18-h EC(50) arsenate concentration of ca. 40 μM, which caused significant changes in the cell shape, growth and ...
متن کاملEffect of different toxic compounds on ATP content and acid phosphatase activity in axenic cultures of Tetrahymena pyriformis.
The sensitivity of protozoa, and particularly ciliated protozoa, to environmental changes suggested a study on the physiological responses arising from exposure to toxic compounds. Tetrahymena pyriformis was used as a test organism in a set of miniaturized assays. The physiological response of this ciliate was assessed in terms of adenosine-5'-triphosphate content and acid phosphatase activity ...
متن کاملLiving unicellular eukaryote Tetrahymena pyriformis as a model for study of mitochondrial energetics in mammalian cells under conditions of reduced oxidative metabolism
Some “animal-like” protozoa are used instead of mammalian cells in diverse investigations. Tetrahymena pyriformis cells in stationary phase of growth and washed from oxidative substrates (T.pyriformis) function under conditions of reduced oxidative metabolism. To elucidate if T.pyriformis can be applied as a model for mitochondrial energetics study in mammalian cells during hibernation, the fea...
متن کاملPackaging of Campylobacter jejuni into Multilamellar Bodies by the Ciliate Tetrahymena pyriformis.
Campylobacter jejuniis the leading cause of bacterial gastroenteritis worldwide. Transmission to humans occurs through consumption of contaminated food or water. The conditions affecting the persistence of C. jejuniin the environment are poorly understood. Some protozoa package and excrete bacteria into multilamellar bodies (MLBs). Packaged bacteria are protected from deleterious conditions, wh...
متن کاملElectron-microscopic observations on the macronuclear development of Stylonychia mytilus and Tetrahymena pyriformis (Ciliophora-Protozoa).
This report describes an ultrastructural investigation of macronuclear development following conjugation in Stylonycltia mytilus (a spirotrichous ciliate) and Tetrahymena pyriformis (a holotrichous ciliate). In S. mytilus, polytene chromosomes are formed in the young macronucleus (macronuclear Anlage). They are subsequently broken between the bands by 'membranous' partitions; the assembly of th...
