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. Assessing the sources of high fecal coliform levels at an urban tropical beach
Recreational water quality is commonly assessed by microbial indicators such as fecal coliforms. Maceió is the capital of Alagoas state, located in tropical northeastern Brazil. Its beaches are considered as the most beautiful urban beaches in the country. Jatiúca Beach in Maceió was found to be unsuitable for bathing continuously during the year of 2011.

3. Bioaccumulation of animal adenoviruses in the pink shrimp
Adenoviruses are among the most promising viral markers of fecal contamination. They are frequently found in the water, sediment and soil of regions impacted by human activity. Studies of the bioaccumulation of enteric viruses in shrimp are scarce. The cities located in the northern coast of the lake systems in Southern Brazil have high urbanization and i

4. Clustering of water bodies in unpolluted and polluted environments based on Escherichia coli phylogroup abundance using a simple interaction database
Different types of water bodies, including lakes, streams, and coastal marine waters, are often susceptible to fecal contamination from a range of point and nonpoint sources, and have been evaluated using fecal indicator microorganisms. The most commonly used fecal indicator is Escherichia coli, but traditional cultivation methods do not allow discrimination

7. Tratamento de esgoto sanitário pelo sistema zona de raízes utilizando plantas de bambu / Sewage treatment by root zone system using bamboo plants.
This study aimed to evaluate the efficiency of three species of bamboo (Guadua angustifolia, Phyllostachys aurea and Phyllostachys bambusoides) in the sanitary sewage treatment, with a vertically downward sub-surface flow root zone system, in Goiânia, GO, Brazil. Sewage from a university was applied to asbestos cement water tanks with 1,000 liters volume ca

9. Kluyveromyces aestuarii, a potential environmental quality indicator yeast for mangroves in the State of Rio de Janeiro, Brazil
Kluyveromyces aestuarii was found in sediments from 7 of 8 mangroves in Rio de Janeiro; and absent only at one site with heavy plastic bag pollution. Its presence suggests influence in other habitats from a mangrove and its absence in a mangrove suggests some non-fecal pollution or other habitat alteration.
