In order to show how environmental factors could influence the spatial and temporal distribution of epibiosis, we investigated the occurrence of the ciliate Rhabdostyla cf. chironomi (Ciliophora, Peritrichia) attached to Chironomidae larvae in an urban stream in southeast Brazil. Samples were collected monthly for 1-year period at five sampling stations(More)
The correct title is given here: Determining the adaptation potential of entomopathogenic nematode multiplication of Heterorhabditis baujardi and Steinernema carpocapsae (Rhabditida: Heterorhabditidae, Steinernematidae) in larvae of Alphitobius diaperinus (Coleoptera: Tenebrionidae) and Galleria mellonella (Lepidoptera: Pyralidae). Pages 139–143: Where it(More)
Several ciliated protists form symbiotic associations with a diversity of microorganisms, leading to drastic impact on their ecology and evolution. In this work, two Euplotes spp. sampled in Rio de Janeiro, Brazil, were identified based on morphological and molecular features as Euplotes woodruffi strain Sq1 and E. encysticus strain Sq2 and investigated for(More)
The aim of this research was to study the ciliated protozoa community at three sampling stations that receive different levels of domestic sewage along the São Pedro Stream in the municipality of Juiz de Fora, Minas Gerais, Brazil, in order to determine the influence of organic pollution on this community and to assess the feasibility of using ciliates as(More)
The bromeliad habitat contributes to a high biodiversity and we recorded three treefrog species as new phoretic agents of ostracods, and a first case of hyperphoresy among treefrogs, ostracods and ciliates, in these habitats of Atlantic Forest. Densities of ciliates and ostracods showed significant relationships suggesting the importance of hyperphoresy for(More)
Data on trichodinid ciliophorans in Brazil are scarce and generally do not use the modern silver-impregnation technique, which is essential to the taxonomy of the group. The present study reports not only on the first occurrence of Trichodina heterodentata in Brazil but also on the first record of this trichodinid infesting tadpoles of the species Rhinella(More)
Apoamphisiella Foissner, 1997 is a genus of hypotrichous ciliates reported to occur in various locations in the world, but that seems particularly widespread in the Americas. In this study, the first record of Apoamphisiella vernalis for Brazil is presented based on a population from the Atlantic Forest of the Minas Gerais state. A redescription of A.(More)
Our objective was to determine the mean production of entomopathogenic nematodes (EPNs) infective juveniles (IJs) from Alphitobius diaperinus and Galleria mellonella larvae and the possible morphometric changes of emergent IJs. Heterorhabditis riobravus and Steinernema carpocapsae nematodes were placed on 20 larvae of each host individually located in Petri(More)
The species composition, prevalence, and average relative abundance of rumen ciliates were analyzed in 16 Brazilian sheep. 28 species of ciliates were identified belonging to 3 families: Isotrichidae, Ophryoscolecidae, and Parentodiniidae. Among these ciliates, Entodinium alces, Metadinium esalqum, and M. rotundatum were found for the first time in sheep,(More)
The morphology and morphometric data of seven populations of Blepharisma sinuosum from southeastern Brazil were investigated. The description is based on live observations, protargol impregnation, and scanning electron microscopy. Blepharisma sinuosum measures 75-255μm in length and 25-93μm in width and has a spindle-shaped body, pink color, a single(More)
