Proteomic response of gill microsomes of Crassostrea brasiliana exposed to diesel fuel water-accommodated fraction

Aquatic Toxicology, 2018
Diesel fuel water-accommodated fraction (diesel-WAF) is a complex mixture of organic compounds that may cause harmful effects to marine invertebrates. Expression of microsomal proteins can be changed by oil exposure, causing functional alterations in endoplasmic reticulum (ER).

MOLECULAR IDENTIFICATION OF CRYPTIC SPECIES OF OYSTERS (GENUS Crassostrea SACCO, 1897) IN THE NORTHEAST ATLANTIC COAST OF BRAZIL

Boletim do Instituto de Pesca, 2019
Oysters of the genus Crassostrea Sacco, 1897 are widely distributed worldwide, being important extractive and cultivation resources in Brazil. Because they have high phenotypical plasticity and congeneric similarity, identifications based on shell ...

Infestation of Crassostrea cf. brasiliana by boring-polychaete polydorids in estuaries from Northeastern Brazil

Journal of Environmental Analysis and Progress, 2017
The presence of polydorids shell-borer and the epifaunal polychaetes on Crassostrea cf. brasiliana were studied in five estuaries in Northeastern Brazil: The prevalence of shell-boring polychaetes in oysters varied significantly, showing dominance of Polydora websteri, with 57% of sampled oysters, and Boccardiella ligerica, with 11%, but the ...

Morphology of the larval shell of three oyster species of the genus Crassostrea Sacco, 1897 (Bivalvia: Ostreidae)

Brazilian Journal of Biology
In this study we describe the morphology of the larval shell of three oyster species of Crassostrea genus. Two species, C. rhizophorae and C. brasiliana, are native to the Brazilian coast, and C. gigas is an introduced species.

Upregulation of biotransformation genes in gills of oyster Crassostrea brasiliana exposed in situ to urban effluents, Florianópolis Bay, Southern Brazil

Ecotoxicology and Environmental Safety, 2016
The release of untreated sanitary sewage, combined with unplanned urban growth, are major factors contributing to degradation of coastal ecosystems in developing countries, including Brazil. Sanitary sewage is a complex mixture of chemicals that can negatively affect aquatic organisms.

Pea crab-oyster interspecific interaction on tropical coast: Brachyuran pinnotherid Zaops ostreum (Say, 1817) living in the host bivalve ostreid Crassostrea brasiliana (Lamarck, 1819)

Revista Brasileira de Gestão Ambiental e Sustentabilidade, 2023
In this study, we report the association between the pea crab Zaops ostreum (Say, 1817) living in the oyster Crassostrea brasiliana (Lamarck, 1819), collected in an estuarine region of Northeast Brazil. Oysters were collected along the mouth of the Santa Cruz Channel, Barra de Catuama (State of Pernambuco), between 2016 and 2017.

Incorporação experimental de Vibrio cholerae O1 não toxigênico em ostras (Crassostrea brasiliana), vivas1

Revista do Instituto Adolfo Lutz, 1999
As ostras são moluscos bivalves que, com freqüência, são consumidas cruas. Podem ser objeto de processos de depuração (descontaminações físicas e químicas), pois este hábito de consumo está associado a eventos de doenças transmitidas por alimentos em vários países.

Crescimento da prodissoconcha de ostras do gênero Crassostrea Sacco, 1897 (Bivalvia, Ostreidae)

Boletim do Instituto de Pesca, 2018
Foi realizado o acompanhamento do crescimento larval de três espécies de ostras do gênero Crassostrea. As espécies Crassostrea rhizophorae (Guilding, 1828) e C. brasiliana (Lamarck, 1819) são ostras nativas do litoral do Paraná e são comercializadas nos
