Antibacterial and cytotoxicity activity in macroalgae extracts: perspectives for the use against pathogenic bacteria from shrimp farms (Litopenaeus vannamei) Biological Sciences
Silva, Giselle Cristina; Soares, Raquel Cavalcante; Carvalho, Fátima Cristiane Teles; Rocha, Rafael dos Santos; Vieira, Regine Helena Silva dos Fernandes; Sousa, Oscarina Viana de.
Some infections caused by pathogenic microorganisms might shows high prevalence in farmed shrimp environments, compromising production and causing economic losses. Therefore, the search for compounds with antibiotic activity has become intensive, following the record of new antimicrobial-resistant bacteria. The study of those bioactive compounds in marine macroalgae has produced satisfactory results, such as the discovery of antibacterial activity against multiresistant strains. Accordingly, this study aims to research antibiotic activity in macroalgae extracts of Chlorophyta, Phaeophyta and Rhodophyta found in the coast of Ceará and also to evaluate the cytotoxicity activity against bacterial strains (Vibrio sp.) from shrimp farms (Litopenaeus vannamei)....

Aquatic microbiota diversity in the culture of Nile tilapia (Oreochromis niloticus) using bioflocs or periphyton: virulence factors and biofilm formation Animal Sciences
Silva, Jéssica Lucinda Saldanha da; Cavalcante, Davi de Holanda; Carvalho, Fátima Cristiane Teles de; Vieira, Regine Helena Silva dos Fernandes; Sá, Marcelo Vinícius do Carmo e; Sousa, Oscarina Viana de.
The following research isolated and identified the main bacterial groups present in the culture of juvenile Nile tilapia in the presence of bioflocs and/or periphyton. The strains were also tested for the production of exoenzymes, indicative of potential virulence factors, and ability to form biofilm. The water samples were taken from tilapia cultured in the presence of bioflocs (T1), in the presence of bioflocs and periphyton (T2), from traditional culture (T3) and from culture in the presence of periphyton (T4). In the growth and selection of the bacterial groups, pour plate method was used, along with the following media: Plate Count Agar (PCA - DIFCO), Aero Pseudo Selective Agar (GSP - Himedia) and Nutrient Agar (AN - Merck). 46 strains were isolated...

Ecotypes and virulence factors of Salmonella spp. detected in shrimp farms in State of Ceara, Brazil Biological Sciences
Carvalho, Fátima Cristiane Teles de; Rodriguez, Marina Teresa Torres; Menezes, Francisca Gleire Rodrigues de; Sousa, Oscarina Viana de; Hofer, Ernesto; Vieira, Regine Helena Silva dos Fernandes.
 Our objective was to group in ecotypes 12 serovars of Salmonella isolated from shrimp farming environments in the State of Ceara (Northeast Brazil). Grouping was done based on genotypic virulence factors. Two groups based on the similarity of the Box-PCR were identified: a group consisting of three strains (01 S. ser. Madelia serovar and 02 S. ser. enterica subs. houtenae) and another group consisting of nine isolates (02 S. ser. Saintpaul serovars; 03 S. ser. Infantis; 02 S. ser. Panama; 01 S. enterica subs. enterica; and 01 S. enterica subs. houtenae). Distribution pattern of the serovars was not influenced by the origin matrices (water and sediment). Plasmid virulence genes pefA and invA were detected, unrelated to the serovar and environmental origin...
