| 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... |

| 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... |

| INTRODUCTION: Recurrent respiratory infections account for most of the morbidity and mortality of cystic fibrosis patients. MATERIALS AND METHODS: The objective was to determine the prevalence of pathogens isolated from lower respiratory tract secretions in cystic fibrosis patients. In this descriptive observational study, data from 69 patients was collected from medical records. RESULTS: The microorganisms that were identified included 36.2% P. aeruginosa, 28.9% S. Aureus, 4.3% K. pneumoniae, 1.5% H. influenzae, 1.5% E. coli, 1.5% S. maltoophilia, and in 27.5% the flora was normal. The prevalence of P. aeruginosa was 83% in patients under two years of age, demonstrating early colonization. CONCLUSION: P. aeruginosa and S. aureus were the most prevalent... |

| The aim of the present study was to evaluate the presence of the periodontal pathogens that form the red complex (Tannerella forsythia, Porphyromonas gingivalis and Treponema denticola) and Aggregatibacter actinomycetemcomitans in patients with chronic periodontitis. The sample consisted of 29 patients with a clinical and radiographic diagnosis of chronic periodontitis based on the criteria of the American Academy of Periodontology (3). Samples for microbiological analysis were collected from the four sites of greatest probing depth in each patient, totaling 116 samples. These samples were processed using conventional polymerase chain reaction, which achieved the following positive results: 46.6% for P. gingivalis, 41.4% for T. forsythia, 33.6% for T.... |

| 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... |

| ABSTRACT: The aim of this study was to conduct a survey on nematodes associated with five cultivated fruit trees growing in the Agroforestry System (AFS) of the municipality of Oiapoque, Amapá, Brazil. Rhizosphere samples were collected from three points at the base of murici ( Byrsonima sp.), soursop ( Annona muricata ), cupuaçu ( Theobroma grandiflorum ), passion fruit ( Passiflora sp.) and peach palm ( Bactris gasipaes ) trees. Four species of phytonematodes were identified, namely Pratylenchus brachyurus, Helicotylenchus dihystera, Mesocriconema xenoplax and Rotylenchulus reniformis . The most prevalent and abundant species was R. reniformis , which was found in the rhizospheres of passion fruit, cupuaçu, soursop, and peach palm. The first record in... |

| En San Martin Texmelucan, Pue., el gladiolo (Gladiolus grandiflorus Hort.) es uno de los cultivos de mayor importancia. En los últimos años ha presentado problemas en su producción, principalmente causados por hongos fitopatogenos y por un desbalance nutrimental. Esta investigación se dividió en tres partes. En la primera el objetivo fue conocer el efecto de la fertilización en la fenología, crecimiento, calidad de flor, rendimiento y sanidad del cultivo de dos variedades de gladiolo; en la segunda se estudió la reproducción in vitro de plantas de gladiolo libres de hongos fitopatógenos, y determinar el mejor ambiente de aclimatación, y en la tercera se identificaron morfológica y molecularmente las especies de Penicillium causantes de la pudrición del... |

| It is extremely important for biodiversity conservation that protected areas are resilient to a range of potential future perturbations. One of the least studied influences on protected area resilience is that of disease. We argue that wildlife disease (1) is a social-ecological problem that must be approached from an interdisciplinary perspective; (2) has the potential to lead to changes in the identity of protected areas, possibly transforming them; and (3) interacts with conservation both directly (via impacts on wild animals, livestock, and people) and indirectly (via the public, conservation management, and veterinary responses). We use southern African protected areas as a case study to test a framework for exploring the connections between... |

| 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... |

| Os carrapatos são artrópodes hematófagos que parasitam muitas espécies de hospedeiros, desde mamíferos até anfíbios, e podem ser encontrados em vários ambientes nas diversas regiões do planeta. O tema ?Carrapatos no Brasil? tem importância, tanto na saúde animal quanto ao aspecto econômico. Os prejuízos, apenas no que tange a cadeia produtiva de bovinos no país, são estimados em 3,2 bilhões de dólares ao ano. Com respeito à saúde pública a bactéria Rickettsia rickettsii, agente da febre maculosa brasileira (FMB), tem os carrapatos por vetores. Contudo, os prejuízos relativos à manutenção da saúde pública não foram ainda estimados, e são incalculáveis quando se trata de perdas de vidas humanas. O Museu do Carrapato tem por objetivo apresentar, de forma... |

| 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... |
