| Objetivou-se estudar a lixiviação do diuron em colunas de solo, além do efeito de métodos de redução da atividade microbiana na degradação deste herbicida em amostras de LATOSSOLO VERMELHO Distrófico (LVd – textura franco-arenosa) e LATOSSOLO VERMELHO Distroférrico (LRd – textura argilosa). Para avaliar a movimentação do diuron (0; 1,6 e 3,2 kg há-1), foram aplicadas lâminas de 0, 20, 40, 60 e 80 mm de água. Na degradação, os métodos de restrição empregados foram: autoclavagem prévia, aplicação de brometo de metila, amoxicilina, captan e amoxicilina+captan, sendo que as amostras foram mantidas na ausência ou presença de luz. Resultados indicam que lâminas superiores a 60 mm foram suficientes para promover movimentação nítida nas amostras de LVd. Para o... |

| ABSTRACT The objective of this study was to verify the kinetics of sorption and desorption of diuron in an Oxisol under application of biochar. The samples were collected in a field experiment conducted in randomized design blocks consisted of 2 base fertilization levels (0 and 400 kg∙ha−1 NPK 00-20-20 fertilizer formula) and 3 doses of biochar (0, 8 and 16 Mg∙ha−1). In the evaluation of sorption and desorption, Batch Equilibrium method was used. The kinetics of sorption and desorption of diuron, total organic carbon, fulvic acid, humic acid and humin, pH and partition coefficient to organic carbon were evaluated. The Freundlich isotherm was adjusted appropriately to describe diuron sorption kinetics in all the studied treatments. The application of... |

| Abstract The pathogenic bacterium Listeria monocytogenes can persist in food processing plants for many years, even when appropriate hygienic measures are in place, with potential for contaminating ready-to-eat products and, its ability to form biofilms on abiotic surfaces certainly contributes for the environmental persistence. In this research, L. monocytogenes was grown in biofilms up 8 days attached to stainless steel and glass surfaces, contributing for advancing the knowledge on architecture of mature biofilms, since many literature studies carried out on this topic considered only early stages of cell adhesion. In this study, biofilm populations of two strains of L. monocytogenes (serotypes 1/2a and 4b) on stainless steel coupons and glass were... |

| Durante las últimas dos décadas las infecciones por Salmonella se han registrado entre las enfermedades más frecuentes, afectando a personas de todas las edades y condiciones sociales y causando numerosas hospitalizaciones y muerte de personas por el consumo de frutas y hortalizas frescas. En frutas, en 2011 el Centro para el Control de Enfermedades y Prevención en EUA reportó un brote de infección por S. Agona asociado con el consumo de papaya fresca en el que 106 personas resultaron afectadas. Mientras que en hortalizas, S. typhimurium se ha aislado de diversas especies entre las que se encuentra el nopal verdura (Opuntia ficus-indica L. Mill) (Quiroz-Santiago, 2009; Hernández et. al. 2009). Debido a que el nopal se consume en fresco para el control de... |

| In recent years recurring political, economic, and environmental crises require questioning and re-evaluating dominant pathways of human development. However, political and economic frameworks seem to encompass deeply rooted resistance to fundamental changes (e.g., global financial crisis, climate change negotiations). In an effort to repair the system as fast as possible, those paradigms, mechanisms, and structures that led into the crisis are perpetuated. Instead of preserving conventional patterns and focusing on continuity, crises could be used as an opportunity for learning, adapting, and entering onto more sustainable pathways. However, there are different ways not only of arguing for sustainable pathways of development but also of conceptualizing... |

| Wild (Th11, Th12 and Th650) and mutant (Th11A80.1, Th12A40.1, Th12C40.1 and Th650-NG7) Trichoderma harzianum strains were stored for 180 days at 5ºC or at 22ºC, in two types of soils. Strains recovered at 90, 120 and 180 days from the two types of soils, retained their full capacity to biocontrol Rhizoctonia solani 618, that produces crown and root rot of tomatoes. Recovery, estimated as colony forming units (cfu) of the wild and mutant strains, showed that all increased their cfu after storage independently of the type of soil and temperature, although kinetic behavior differed among strains. Ratios of recovery after storage in type B soil/ type A soil or at 22ºC/5ºC, higher or lower than one respectively, allowed to establish that Th11 and Th12 were the... |

| The contamination of coastal areas by potentially pathogenic enteric bacteria is of concern for the sustainability of some uses, such as shellfish farming, recreational shellfish harvesting and bathing. The contamination of these environments may occur through the land-spreading of livestock wastes, animal feces deposited on pastures, wastewaters from slaughterhouses or from municipal wastewater treatment plants. The presence of these bacteria in coastal environment may present a potential risk to human health. In fact, shellfish-borne outbreaks or human infections may occur by the consumption of shellfish from contaminated areas or the ingestion of water during bathing in contaminated waters, respectively. To date, few studies focusing on the presence and... |

| Human and animal fecal wastes and urine contain a large number of different viruses that can enter the environment through the discharge of waste materials from infected individuals. Despite the high diversity of viruses that are introduced into the environment by human fecal pollution, only a few have been recognized to cause disease in association with consumption of contaminated shellfish. Viruses are present in shellfish in very low numbers. Nevertheless, they are present in sufficient quantities to pose a health risk as presented. This low level of contamination has made it necessary to develop highly sensitive viral extraction methods to ensure virus recovery from shellfish tissues. The most common route for accidental contamination is after heavy... |

| Oysters, being filter feeders, can accumulate some human pathogens such as norovirus, a highly infectious calicivirus, most common cause of acute gastroenteritis worldwide. Accumulated virus decays over a period of days to weeks, possibly rendering contaminated oysters safe again. Sensitive molecular methods have been set up for shellfish analysis but without answering the question of infectious virus detection. Using the Tulane virus (TV), a norovirus surrogate that recognizes the same ligand as human norovirus in oyster tissues, the genome and infectious virus decay rates were estimated using inverse linear regression in a Bayesian framework for genome copies. Infectivity decreased faster than genome copies but infectious viruses were detected for... |

| Healthy cattle are the primary reservoir for O157:H7 Shiga toxin-producing E coil responsible for human food-borne infections. Because farm environment acts as a source of cattle contamination, it is important to better understand the factors controlling the persistence of E. coil O157:H7 outside the bovine gut. The E. coil O157:H7 strain MC2, identified as a persistent strain in French farms, possessed the characteristics required to cause human infections and genetic markers associated with clinical O157:H7 isolates. Therefore, the capacity of E. coil MC2 to survive during its transit through the bovine gastro-intestinal tract (GIT) and to respond to stresses potentially encountered in extra intestinal environments was analyzed. E. coil MC2 survived in... |
