1. Enterococcus spp. Resistant to Multiple Antimicrobial Drugs and Determination of Fecal Contamination Levels in Mangrove Oysters (Crassostrea rhizophorae)
ABSTRACT The aim of this study was to determine and compare the Most Probable Number (MPN) of Total Coliforms (TC), Escherichia coli and Enterococcus spp. and to characterize the antimicrobial resistance profiles of Enterococcus spp. isolated from oysters collected in the Barra de Guaratiba Mangrove, Rio de Janeiro, Brazil. The enumeration of E. coli has bee

2. Marcadores orgânicos moleculares como ferramentas no monitoramento ambiental: Avaliação da distribuição de Alquilbenzeno Lineares (LABs) em organismos e sedimentos, como indicativo de exposição ao esgoto em áreas costeiras / Organic molecular markers as tools in environmental monitoring: Evaluation of Linear Alkylbenzene (LABs) distribution in organisms and sediments, as indicative of exposure to sewage in coastal areas
The sewage disposal in coastal areas can cause impacts to marine life, altering the balance of the ecosystem and biodiversity and causing serious diseases in humans. In this study, the concentration of a set of molecular markers for the introduction of organic sewage into the marine environment: linear alkylbenzene (LAB), in samples of sediment, oysters (Cra

3. DistribuiÃÃo da malacofauna em pilares dos terminais portuÃrios de Cearà - Brasil, com Ãnfase no bivalve invasor Isognomon Bicolor / Distribution of mollusc pillars of the port terminals of Cearà - Brazil, with emphasis on bivalve invader Isognomon Bicolor
Terminais portuÃrios adicionam estruturas artificiais ao ambiente marinho propiciando o estabelecimento de organismos epibÃnticos nativos e espÃcies exÃticas devido à intensa circulaÃÃo de navios. O presente estudo caracterizou e comparou a composiÃÃo especÃfica e a distribuiÃÃo batimÃtrica da malacofauna associada aos pilares dos terminais port

4. Determinação da composição química do molusco Anadara notabilis encontrado em Galinhos no Rio Grande do Norte
Tendo em vista a grande biodiversidade existente no litoral brasileiro, onde muitas espécies ainda são pouco conhecidas, inclusive sob o aspecto nutricional, e considerando que os moluscos bivalves se constituem em um recurso natural de boa aceitação pela população mundial, escolheu-se o molusco bivalve Anadara notabilis, por não ter sido encontrado n

5. Presença de dinoflagelados bentônicos potencialmente tóxicos: identificação do perigo em áreas destinadas à maricultura na Baía de Sepetiba, RJ. / Presence of potentially toxic benthic dinoflagellates: identification of hazard in shellfish growing areas in the Sepetiba Bay, RJ.
The malacoculture (cultivation of shellfish) is the second most significant activity of the Brazilian mariculture, where the cultivation of bivalve molluscs (mussels, oysters and scallops) stands out nationally. The bivalves show an excellent nutritional value when they are used as food by humans, containing a great biological value of protein, low in fat, v

6. Avaliação da contaminação de ostras (Crassostrea rhizophorae) por especies de Cryptosporidium e Giardia em um ambiente de estuario do litoral de São Paulo / Evaluation of the contamination of oysters (Crassostrea rhizophorae) by species of Cryptosporidium and Giardia in a estuarine environment from São Paulo coast
Bivalve molluscs are great filter feeders that may accumulate and concentrate substances, particles and even pathogens in their tissues, if the places that they inhabit or are cultivated receive contaminated effluents dispose. These animals, which serve as biological indicators of faecal contamination, may transmit the protozoa accumulated in their tissues,

7. Determinação de ions metalicos em moluscos bivalves do manguezal da região petrolifera de São Francisco do Conde - Reconcavo Baiano / Determination of metallic ions in bivalve molluscs from the petroliferous region of São Francisco do Conde Mangrove - Reconcavo Baiano
The pollution of oceans, bays and estuaries as a result of industrial and domestic effluents that contain metallic ions is one of the most important factors that lead to the contamination of bivalve molluscs. These organisms are greatly affected by the bioaccumulation of inorganic species, even at low concentrations, reflecting the environmental contaminatio

8. Padrões de abundância, riqueza e diversidade de moluscos bivalves na plataforma continental ao largo de Ubatuba, São Paulo, Brasil: uma comparação metodológica
The diversity and richness patterns of bivalve molluscs were studied on the continental shelf of Ubatuba (23º38'S, 45º14'W and 23º25'S, 44º51'W) between 15-120 metres depth. The samples were taken with a rectangular dredge and a beam trawl. The results showed higher values of richness, diversity and evenness for inner shelf (from coast to nearly 50 m dep

9. Avaliação de variações bioquímicas em moluscos bivalves em resposta ao estresse ambiental / Evaluation of biochemical variations in bivalve molluscs in response to environmental stress
In this work, some biochemical systems were evaluated in different tissues of bivalve mollusks, in response to different stress, in order to verify the possibility of use of these systems as pollution bioindicators in marine environmental monitoring studies, as well as to verify the influence of environmental variations not related to pollution on these syst

12. Detection and Identification of tdh- and trh-Positive Vibrio parahaemolyticus Strains from Four Species of Cultured Bivalve Molluscs on the Spanish Mediterranean Coast▿
Presented here is the first report describing the detection of potentially diarrheal Vibrio parahaemolyticus strains isolated from cultured bivalves on the Mediterranean coast, providing data on the presence of both tdh- and trh-positive isolates. Potentially diarrheal V. parahaemolyticus strains were isolated from four species of bivalves collected from bot
