1. Cryptocaryon irritans, a ciliate parasite of an ornamental reef fish yellowtail tang Zebrasoma xanthurum
Resumo Cryptocaryon irritans é um protozoário ciliado parasita obrigatório de peixes marinhos selvagens e cultivados. Causa a doença dos “pontos brancos”. Infecções por esse patógeno pode causar perdas significativas para aquaristas e para marinocultura comercial em todo o mundo. Este estudo relata a ocorrência de C. irritans parasitando a espéc

2. Physiological reorganization in the hypotrich ciliate Apoamphisiella vernalis (Protista, Ciliophora, Hypotricha)
ABSTRACT Physiological reorganization is described for the first time for the hypotrich ciliate genus Apoamphisiella Foissner, 1997, based on a population of A. vernalis (Stokes, 1887) Berger, 2006 collected from an eutrophic pond in the state of Minas Gerais, Brazil. Stomatogenesis is epiapokinetal, and the cirral pattern reorganizes from six typical fronto

3. Quantitative and differential analysis of ciliate protozoa in rumen content samples filtered before and after fixation
The objective of this study was to assess whether the straining of rumen content samples influences the estimation of protozoal density. Ninety rumen samples were obtained from 30 cattle (three samples per animal). The samples were subjected to one of three treatments at the moment of collection: 1) fixation informalin without straining(control treatment), 2

4. Quantitative study of Trichodina heterodentata (Ciliophora: Mobilia) infrapopulations infesting tadpoles of a Brazilian endemic toad Rhinella pombali (Anura: Bufonidae)
In this work we investigated the quantitative aspects of the relationship between Rhinella pombali (Baldissera, Caramaschi & Haddad, 2004) tadpoles and their trichodinid ectoparasites. Specimens were collected from a small stream located at an agricultural area between rainforest fragments in southeastern Brazil. A total of 80 tadpoles were investigated. Tri

6. Morphometric study of a Brazilian strain of Carchesium polypinum (Ciliophora: Peritrichia) attached to Pomacea figulina (Mollusca: Gastropoda), with notes on a high infestation
During an ecological study of the epibiotic relationship between ciliate protists and Pomacea figulina (Spix, 1827) (Gastropoda, Ampullariidae), originating from an urban stream in southeast Brazil, a high infestation by the peritrich ciliate Carchesium polypinum (Linnaeus, 1758) Ehrenberg, 1830 (Ciliophora, Peritrichia) associated to the shell of one mollus

7. ASPECTOS MORFOLÓGICOS E ECOLÓGICOS DO PROTISTA CILIADO RHABDOSTYLA CHIRONOMI KAHL, 1933 (CILIOPHORA, PERITRICHIA) EPIBIONTE DE LARVAS DE QUIRONOMÍDEOS EM UM CÓRREGO URBANO DO SUDESTE DO BRASIL
In the present study, both taxonomy and morphology aspects of the epibiont ciliate Rhabdostyla chironomi found in São Pedro stream (Juiz de Fora-MG), as well some ecological aspects of this epibiotic relationship between the peritrich and chironomid larvae from genus Chironomus gr. decorus. The present dissertation is divided into four parts. In the first o

8. Phytoplankton-aloricate ciliate community in the Bahía Blanca Estuary (Argentina): seasonal patterns and trophic groups
O padrão sazonal da comunidade de fitoplâncton-ciliados aloricados é um indicador adequado das relações tróficas e reciclagem de nutrientes nos ambientes costeiros. A abundância, biomassa e composição da comunidade de fitoplâncton-ciliados foram determinadas por classes de tamanho durante um ciclo anual no estuário de Bahía Blanca. Além disso, f

10. ADIÇÃO DE SAL COMUM (NaCl) NA RAÇÃO E NA ÁGUA NO CONTROLE DE Ichthyophthirius multifiliis E CRESCIMENTO DE JUVENIS DE JUNDIÁ Rhamdia quelen (HEPTAPTERIDAE) / DIETARY AND WATERBORNE SALT (NaCl) ON THE CONTROL OF Ichthyophthirius multifiliis AND GROWTH OF JUVENILE SILVER CATFISH Rhamdia quelen (HEPTAPTERIDAE)
The increasing proliferation of freshwater fish parasites causes concerns to the fish farmers. One of the main diseases in fish culture is the ciliate protozoan Ichhtyophthirius multifiliis, because severe infections of this parasite provoke high mortalities, causing economical losses to the producers. The objective of this study was to verify the efficacy o

12. Abundance and species composition of planktonic Ciliophora from the wastewater discharge zone in the Bahía Blanca Estuary, Argentina
The specific composition and abundance variation of the ciliate community from a wastewater discharge zone in the Bahía Blanca estuary, Argentina, were studied all throughout a year, from June 1995 to May 1996. The polluted area exhibited high values of particulate organic matter and nutrients, particularly phosphates. Aloricate ciliates were represented by
