| Antibacterial properties and chemical characterization of the essential oils from summer savory (Satureja hortensis) extracted by microwave-assisted hydrodistillation (MAHD) were compared with those of the essential oils extracted using the traditional hydrodistillation (HD) method. While MAHD at 660 W required half as much time as HD needed, similar antibacterial efficacies were found from the essential oils obtained by the two extraction methods on two food pathogens (Staphylococcus aureus, a gram positive bacterium, and Escherchia coli, a gram negative bacterium). Also, as it was the case with the essential oils extracted by HD, that of MAHD indicated greater influence on S. aureus than on E. coli. The compositions of the extracted essential oils were... |

| Antimicrobial drugs are fed to animals at low levels to treat diseases, to promote growth, and to increase feed efficiency. Incorporating low levels of antimicrobial drugs in livestock feeds has been shown to be a factor stimulating the development of antimicrobial drug resistant bacteria in livestock. Since many of the drugs used to treat livestock are the same as or are related to drugs used in human health care, there is concern that resistant organisms may pass from animals to humans through the handling of animals or food derived from animals. The movement of pathogens from animals to humans, and vice versa, has been documented, but the extent to which it has occurred or could occur is unknown. Although it is estimated that as little as 10 percent of... |

| Apples possess many beneficial properties for the human health related with their high content in phenolic compounds. The antimicrobial effect of these compounds from the skin of two apple varieties, Royal Gala and Granny Smith, against human pathogens was examined. The phenolic compounds were extracted with the following solvents: A, acetone: water: acetic acid; B, ethyl acetate: methanol: water and C, ethanol: water. Total phenolic, flavonoid and non-flavonoid contents were analyzed in the extracts. The antimicrobial effect was determined using the agar diffusion method. The highest inhibitory effect of both apple varieties corresponded to extract A, which contained a high phenolic content. The Granny Smith extracts with higher phenolic content presented... |

| Abstract Amazonian biodiversity is increasingly threatened due to the weakening of policies for combating deforestation, especially in Brazil. Loss of animal and plant species, many not yet known to science, is just one among many negative consequences of Amazon deforestation. Deforestation affects indigenous communities, riverside as well as urban populations, and even planetary health. Amazonia has a prominent role in regulating the Earth’s climate, with forest loss contributing to rising regional and global temperatures and intensification of extreme weather events. These climatic conditions are important drivers of emerging infectious diseases, and activities associated with deforestation contribute to the spread of disease vectors. This review... |

| The present work aimed characterize isolates of C. lindemuthianum race 65 from different regions in Brazil by ITS sequencing. A total of 17 isolates of race 65, collected in the states of Mato Grosso, Minas Gerais, Paraná, Santa Catarina and São Paulo, were studied. Analysis of the sequences of isolates 8, 9, 12, 14 and 15 revealed the presence of two single nucleotide polymorphisms (SNPs) in the ITS1 region at the same positions. These isolates, when analyzed together with the sequence of isolate 17, revealed a SNP in the ITS2 region. The highest genetic dissimilarity, observed between isolates 11 and 3 and between isolates 11 and 10, was 0.772. In turn, isolates 7 and 2 were the most similar, with a value of 0.002 for genetic distance. The phylogenetic... |

| The different serotyping systems, based on thermostable O antigens, reported for <i>Vibrio anguillarum</i> and <i>V. ordalii</i> were compared by quantitative agglutination, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and subsequent silver staining or Western blotting (immunoblotting) of purified lipopolysaccharide (LPS), using polyclonal rabbit antisera. The results demonstrate that 16 different serotypes within <i>V. anguillarum</i> (designated 01 to 016) can be distinguished. Each of these serotypes is characterized by a distinct polysaccharide banding pattern, as revealed by silver-stained gels of purified LPS. The comparative analysis allowed a complete alignment of the different stereotypes for the... |

| RESUMO: As doenças que ocorrem na soja são responsáveis por severas perdas para os produtores em todo o mundo. Para o controle das principais doenças, a maneira mais prática e econômica tem sido o uso da resistência genética. Objetivando um melhor uso do germoplasma de soja disponível, métodos de seleção de plantas com resistência a Meloidogyne javanica, Heterodera glycines, Diaporthe phaseolorum, Microsphaera dissusa, Fusairum solani, Cercospora sojina e ao vírus da necrose da haste são apresentados. As linhagens avaliadas foram obtidas dos cruzamentos BRS 133 x PI 595099 e Coodetec 201 x PI 595099. Informações adicionais sobre os patógenos abordados e duraçãodo ciclo e produtividade das linhagens avaliadas são também apresentadas. ABSTRACT: Soybean... |

| The first national census concerning shellfish culture in France was carried out in 2002. The main purpose was to provide accurate and comprehensive information on the number and structure of the companies using an in depth review of production factors (leases, plants, equipment's, labour and qualifications), and a survey of cultural practices up to the market level. Moreover, the census aimed to quantify the bivalve sales dedicated to consumption and to measure the livestock transfers among rearing shellfish production areas at different developmental stages: spat, intermediate products and fully grown marketable products. The French oyster production reached 109 000 metric tons in 2001. The main production was observed in Poitou-Charentes region... |
