1. Helminth parasites in two populations of Astronotus ocellatus (Cichliformes: Cichlidae) from the eastern Amazon, Northern Brazil
Resumo Este estudo comparou a estrutura das comunidades de helmintos parasitos em duas populações de Astronotus ocellatus de duas localidades do Estado do Pará, leste da Amazônia brasileira. Hospedeiros do rio Tapajós foram infectados por Posthodiplostomum sp. metacercarie, larvas de Contracaecum sp. e Pseudoproleptus sp., com predomínio de Contracaecu

2. Community ecology of parasites in four species of Corydoras (Callichthyidae), ornamental fish endemic to the eastern Amazon (Brazil)
Abstract Abstract: This study compared the parasites community in Corydoras ephippifer, Corydoras melanistius, Corydoras amapaensis and Corydoras spilurus from tributaries from the Amapari River in State of Amapá (Brazil). A total of 151 fish of these four ornamental species were examined, of which 66.2% were parasitized by one or more species, and a total

3. Acute schistosomiasis diagnosis: a new tool for the diagnosis of schistosomiasis in a group of travelers recently infected in a new focus of Schistosoma mansoni
IntroductionThe diagnosis of schistosomiasis mansoni on early stages of infection is important to prevent late morbidity. A simple, cheap, sensitive and specific assay for routine diagnosis of schistosome infection based on the detection of specific IgG for schistosomula tegument antigens (ELISA-SmTeg) was developed by our group.MethodsWe describe here an ac

4. Community structure of metazoan parasites of silverside, Odontesthes bonariensis (Pisces, Atherinopsidae) from Argentina
The helminth communities of silverside, Odontesthes bonariensis (Valenciennes, 1835), from two Argentinean lagoons were studied and compared at component community and infracommunity levels. Nine helminth species were found: five digeneans (Austrodiplostomum cf. mordax, Ascocotyle (Phagicola) cf. diminuta, Ascocotyle sp., Thometrema bonariensis and Saccocoel

5. A comparative study of the TF-Test®, Kato-Katz, Hoffman-Pons-Janer, Willis and Baermann-Moraes coprologic methods for the detection of human parasitosis
This study compares the diagnostic accuracy of the TF-Test® (TFT) for human parasitosis with results obtained using the traditional Kato-Katz (KK), Hoffman-Pons-Janer (HPJ), Willis and Baermann-Moraes (BM) techniques. Overall, four stool samples were taken from each individual; three alternate-day TFT stool samples and another sample that was collected in a

6. Influência das características ambientais na comunidade de helmintos parasitas de Leptodactylus Podicipinus (Anura, Leptodactylidae) de lagoas do Pantanal da Nhecolândia, Corumbá, Mato Grosso do Sul, Brasil / Environmental variables influencing Helminth Community of Leptodactylus Podicipinus (Anura, Leptodactylidae) from ponds in the South-eastern Pantanal, Brazil
Um dos pontos centrais em ecologia é entender os padrões de distribuição e abundância de espécies, que em termos gerais são determinados pela dispersão e pelas condições abióticas e bióticas do ambiente. As condições ambientais e estrutura do ecossistema são também importantes na relação entre parasitas e hospedeiros e na determinação da

7. The prevalence of schistosomiasis in school-aged children as an appropriate indicator of its prevalence in the community
School-aged children (6-15 years) from the endemic area of Pernambuco were evaluated both as a target group for and an indicator of schistosomiasis control in the community. Parasitological data were drawn from baseline stool surveys of whole populations that were obtained to diagnose Schistosoma mansoni infection. Nineteen representative localities were sel

8. Ecologia geografica de Tropidurus torquatus (Squamata : Tropiduridae) em areas de restinga da costa sudeste e sul-nordeste do Brasil : aspectos reprodutivos, ecologia termica e comunidades de nematodeos associados
Studies of geographical ecology can detect variation in a species ecological attributes along its geographical range, and determine the extent to which historical factors and/or local environmental factors can explain such variations. The wide geographic distribution of the tropidurid lizard Tropidurus torquatus makes it a good model for geographical ecology

9. Estructura comunitaria de helmintos de perros vagabundos de San Juan de Lurigancho, Lima, Perú
Thirty stray dogs Canis familiaris Linnaeus, 1758 were collected in San Juan de Lurigancho, Lima, Peru, between January and March 1997 and necropsied for helminths. Three species were collected: the cestodes Dipylidium caninum (Linnaeus, 1758) Railliet, 1892 and Taenia pisiformis (Bloch, 1780) and the nematode Toxocara canis (Werner, 1782) Stiles, 1905. Fift
