2. Dermocystidium sp. in the gills of farmed Oreochromis niloticus in Brazil
Abstract: The genus Dermocystidium is very comprehensive in the host and site of infection, however this is the first report of the occurrence of Dermocystidium sp. in the gills of Nile tilapia. This study was carried out in a fish farming located in the state of Santa Catarina, Brazil. No mortalities were reported in the facility studied and the animals wer

3. Histopathological effect of sub-lethal concentration of aluminum phosphide (phostoxin) on Clarias gariepinus juveniles
Abtsract: The study evaluated the effect of sub-lethal concentration of phostoxin on Clarias gariepinus juveniles. C. gariepinus juveniles belonging to the same cohort (40.1±1.2g; 18.1±1.1cm) from a commercial fish farm were randomly placed ten in each of 15 plastic tanks containing 15 liters of water. They were exposed for 96 hrs to three sub-lethal conce

4. Effects of sub-lethal exposure of lead acetate on histopathology of gills, liver, kidney and muscle and its accumulation in these organs of Clarias gariepinus
The aim of this work was to study the effects of sub-lethal exposure of lead acetate on the histopathology of the gills, liver, kidney and muscle and its accumulation in these organs of Clarias gariepinus. Results showed that lead accumulation in the tissues of C. gariepinus was dependent on the exposure period and lead concentration. Gills and liver were th

5. Biomarcadores comportamentais, histopatológicos e proteômicos da toxicidade aguda da formulação comercial do herbicida glifosato em poecilia reticulata / Behavioral biomarkers, histopathological, and proteomic acute toxicity of the commercial formulation of glyphosate in Poecilia reticulata
O mecanismo de toxicidade aguda da formulação comercial de glifosato, Roundup Transorb (RDT), foi investigado para as brânquias do guaru (Poecilia reticulata) por meio de tecnologias proteômicas associadas às análises dos índices histopatológicos (HIs), seguido da quantificação das lesões histopatológicas branquiais. Além disso, o presente traba

6. Concentração de metais pesados em peixes teleósteos do rio Piracicaba, Minas Gerais, Brasil / Concentration of heavy metals in teleost fish species from Piracicaba River, Minas Gerais state, Brazil
Metais pesados ocorrem naturalmente no ambiente, entretanto atividades antropogênicas provocam aumento destes nos ecossistemas aquáticos, o que ameaça a saúde dos organismos aquáticos e terrestres, inclusive o homem. Assim, objetivou-se determinar a contaminação por metais pesados e seus efeitos através do biomonitoramento de peixes teleósteos do ri

7. Ecophysiological aspects of Astyanax fasciatus and Pimelodus maculatus from Furnas dam (MG): morpho-functional evaluation of the gills and hematological variables / Aspectos fisioecológicos de Astyanax fasciatus e Pimelodus maculatus (teleósteos) do reservatório da UHE de Furnas, MG : avaliação morfofuncional das brânquias e variáveis hematológicas
The aim of this study was to evaluate the morphofunctional structure of the gills and the hematological variables of Astyanax fasciatus and Pimelodus maculatus living on Furnas Dam Reservoir (Minas Gerais State, Brazil) and analyses the influence of water quality on these parameters. The fishes were collected in five sites (FU10: Turvo; FU20: Guapé; FU30: B

8. Histopathology of gills, kidney and liver of a Neotropical fish caged in an urban stream
Alterações histológicas nas brânquias, rim e fígado foram usadas para estudar a saúde da espécie neotropical de peixe Prochilodus lineatus, submetida a testes in situ por 7 dias em um ribeirão urbano contaminado e em um local de referência, durante o inverno e o verão. Nos peixes confinados no ribeirão urbano as lesões mais comumente encontradas

9. Análise das respostas citogenotóxicas e histopatológicas do peixe Trematomus newnesi exposto à água do mar diante da Estação Antártica Brasileira "Comandante Ferraz", Ilha Rei George, Antártica / Analysis of cytogenotoxic and histopathologic responses of the fish Trematomus newnesi exposed to seawater in front of the Brazilian Antarctic Research Station "Comandandante Ferraz", King George Island, Antarctica.
Many countries have installed research stations in Antarctica. Petroleum hydrocarbons and the sewage disposed into the sea by the stations are potential sources of pollution in Antarctica. Trematomus newnesi specimens were used to assess genotoxic potential and histopathology of the liver and gills of the water surrounding the Brazilian Antarctic Station ?Co

10. Avaliação dos impactos de agrotóxicos na região do Alto Mogi-Guaçu (MG) por meio de ensaios laboratoriais com Danio rerio (Cypriniformes, Cyprinidae) / Evaluation of pesticides impacts in the Mogi-Guaçu river (MG) using laboratorial assays with Danio rerio (Cypriniformes, Cyprinidae)
O município de Bom Repouso, região da nascente do rio Mogi-Guaçu, está localizado a sudoeste do Estado de Minas Gerais, sendo reconhecido nacionalmente pela produção de morango - o município é responsável por 40% da produção nacional - e batata inglesa - o Estado é o primeiro produtor nacional desta cultura. Esses cultivos, porém, geram impactos

11. A new species of Henneguya, a gill parasite of Astyanax altiparanae (Pisces: Characidae) from Brazil, with comments on histopathology and seasonality
A new species of Myxosporea, Henneguya chydadea, is described parasitizing the gills of Astyanax altiparanae collected from a lake on Rio das Pedras farm near Campinas, state of São Paulo, Brazil. Of the fish examined, 88.3% had gills parasitized by myxosporeans. The prevalence of the parasite ranged from 80% in the spring and fall, 93% in the summer and 10

12. Characterization of “Candidatus Piscichlamydia salmonis” (Order Chlamydiales), a Chlamydia-Like Bacterium Associated With Epitheliocystis in Farmed Atlantic Salmon (Salmo salar)
To characterize intracellular gram-negative bacteria associated with epitheliocystis in farmed Atlantic salmon (Salmo salar), gills with proliferative lesions were collected for histopathology, conventional transmission and immunoelectron microscopy, in situ hybridization, and DNA extraction during epitheliocystis outbreaks in Ireland and Norway in 1999 and
