| The objective of this study was to record and describe the morphological changes and the ingestion mechanisms of Frontonia leucas (Ehrenberg, 1833) according to the food type and to relate the food ingested with the different environmental conditions in a lotic system, namely São Pedro stream, located in the municipality of Juiz de Fora, Minas Gerais, Brazil. We sampled three points on a monthly basis from August 2002 to June 2003, each of which receiving different levels of untreated sewage. We prepared culture media for the ciliate specimens containing filtered water from each point and the types of food observed inside F. leucas (cyanobacteria, diatoms, desmids and testate amoebas). We observed the ingestion mechanisms of F. leucas in vivo, under a... |

| In samples of raw sewage collected from a sewage treatment plant in Rio de Janeiro (ETE-Penha), we found populations of two species, Deviata estevesi Paiva & Silva-Neto, 2005 and Deviata brasiliensis sp. nov. The organisms were studied in vivo under phase contrast microscopy, differential interference contrast (DIC), and after protargol-impregnation. The population of D. estevesi exhibited more extensive variation in cirral pattern than previously described. The interphasic organisms of new species D. brasiliensis sp. nov. are distinguishable from their congeners based on a series of morphometric features: cirral row R3 usually presents 1-3 cirri behind the right frontal cirrus, on average there are four macronuclear nodules, and, during... |

| Species composition and distribution of ciliates were investigated in the rumen contents of 15 domestic sheep (Ovis aries) living in Izmir, Turkey. Twenty-three species and 11 morphotypes belonging to nine genera were identified. The density of ciliates was 118.3 +/- 63.5 x 10 4 cells ml(-1), and the mean number of ciliate species per host was 13.5 +/- 5.3. Entodinium simulans was the most abundant species, with a prevalence of 100%. Two morphotypes of Diplodinium flabellum were identified, such as D. flabellum m. aspinatum and D. flabellum m. monospinatum, and E. simulans m. dubardi was found for the first time in domestic sheep in Turkey. The scanning electron microscopic observations of Entodinium longinucleatum, E. bursa, E. rectangulatum m.... |
