| 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... |

| The Ifremer Repamo network (REseau de PAthologie des MOllusques) is the national surveillance network in charge of monitoring marine mollusc health on French coastlines. It is commissioned to enforce the official regulations and to provide a public service, under the supervision of the competent authority (DGAL Veterinary Directorate) in the Ministry.of Agriculture and Fisheries. Its goals are to prevent the introduction and the dissemination of infectious agents, in particular pathogens involved in reportable diseases, and to monitor the changes in the pathogens already present on the French coasts. |

| Rearing of Crassostrea gigas is the most economically important aquaculture activity in France. Bacteria belonging to Vibrio genus constitute one of the most abundant bacterial group in marine ecosystems. Two Vibrio species, V. splendidus and V. aestuarianus, were associated with many cases of mortality events in reared C. gigas spat and juvenile oysters, commonly during summer. This summer mortality syndrome has been extensively documented as the result of complex interactions between pathogens, host and environmental conditions. This work aims to study the Vibrio-host interactions and their modulations according to the virulence of pathogens and the genetic and/or physiological parameters of the host. These factors will be characterized by in vitro and... |

| The chief importance of hemocytes as immune effectors in molluscs has led to develop researches for in vitro culture. The chemiluminescence technique has been used to estimate the phagocytosis capacity of Crassostrea gigas hemocytes according to different culture media and times. Sea water was used as a basic medium. Additives, such as antibiotics or glucose and buffers, such as Tris or Hepes, were tested as weIl as artificial sea water. Hemocyte chemiluminescence activities were recorded at t=o in relation to the medium composition. The highest values were observed when hemocytes were kept in sea water without any modification. Whichever medium, chemiluminescence activity was substantially decreased when hemocytes were previously kept in vitro for a few... |

| Abnormal mortality outbreaks occurred in the majority of Pacific oyster (Crassostrea gigas) producing areas in France in 2008 during the summer period. These outbreaks were usually sudden and severe (up to 100%) and affected essentially spat (oysters less than 1 year-old) and juveniles (12 to 18 month-old oysters). Crassostrea gigas was the single affected species Mortality outbreaks were first observed from mid May to mid June in Brittany, Vendée, Charente Maritime and Mediterranean coast A second episode of massive mortality events was reported at the end of June and the beginning of July. All oyster production sites were affected except some particular locations including Arcachon Bay and Brittany. Mortality occurred latter in Arcachon Bay in August.... |

| Pacific oysters were introduced into west coast of the USA from Matsushima Bay in Japan, infected with low levels of Haplosporidiumsp. identical to H.nelsoni(MSX) which causes high mortalities of Eastern oyster (C. virginica). A highly specific and sensitive DNA probe for H. nelsonican also detect Haplosporidium sp. in C.gigas of western US and Japan (Burreson and Stokes 2000).In 2002, H. nelsoni was detected in Japan using the same probe (Kamaishi and Yoshinaga 2002).Lesson: it appears that H. nelsoni does not cause serious disease in Pacific oysters; H. nelsoniis now speculated to have been introduced into the Pacific US by apparently healthy but infected C. gigas. Infected C. gigaswere introduced onto the east coast of the US where the parasite shifted... |

| The multifactorial etiology of massive Crassostrea gigas summer mortalities results from complex interactions between oysters, opportunistic pathogens and environmental factors. In a field survey conducted in 2014 in the Mediterranean Thau Lagoon (France), we evidenced that the development of the toxic dinoflagellate Alexandrium catenella, which produces paralytic shellfish toxins (PSTs), was concomitant with the accumulation of PSTs in oyster flesh and the occurrence of C. gigas mortalities. In order to investigate the possible role of toxic algae in this complex disease, we experimentally infected C. gigas oyster juveniles with Vibrio tasmaniensis strain LGP32, a strain associated with oyster summer mortalities, after oysters were exposed to Alexandrium... |
