Fenología, propagación in vitro y enfermedades del gladiolo en San Martín Texmelucan, Puebla.
Provedor de dados: 32
Autores: González Pérez, Enrique.
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...

Modulations of the interactions between pacific cupped oyster Crassostrea gigas and Vibrio according to bacterial virulence and to genetic and physiological status of the host : Methodology and first results
Provedor de dados: 5
Autores: De Decker, Sophie; Normand, Julien; Duperthuy, Marylise; Boudry, Pierre; Saulnier, Denis.
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...

Autores: Boulo, Viviane; Hervio, Dominique; Morvan, Annie; Bachere, Evelyne; Mialhe, Eric.
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....

An infection of Ruditapes decussatus (Bivalvia) by Rickettsia
Provedor de dados: 5
Autores: Mialhe, Eric; Chagot, Dominique; Boulo, Viviane; Comps, Michel; Ruano, Francisco; Grizel, Henri.
The authors report the presence of a Rickettsia in Ruditapes decussatus from natural populations of the Algarve (Portugal). Light microscopic shows infections of varying importance in gill tissues. Some enclose small procaryotic colonies (cp) scattered in all lamellae; in others, the colonies are scarce and hypertrophic (100 mu m). These different pictures suggest an amplification process. Digestive diverticulae may also be infected, but to a lesser extent. The ultrastructural features of this intravacuolar (mvd: densified vacuolar membrane) procaryote (P) and its multiplication by scission without a complex developmental cycle allows its classification in the order Rickettsiales.

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...

Dynamique des populations de palourdes japonaises (Ruditapes philippinarum) dans le bassin d'Arcachon : conséquences sur la gestion des populations exploitées
Provedor de dados: 5
Autores: Dang, Cecile.
The Manila clam Ruditapes philippinarum was introduced into Arcachon Bay at the beginning of the 1980s for aquaculture purposes. It rapidly naturalized in all intertidal flats of the lagoon. Nowadays, Arcachon Bay ranks at the first French place in terms of exploitable stock. However, recent stock assessments have shown an unbalance size structure with a deficit in juvenile and adult clams (&gt; 38 mm shell length). These alarming patterns asked many questions on the sustainability of Manila clam populations within Arcachon Bay and have motivated the present thesis. This study aimed to better understand the population dynamics of this species and also some factors controlling this dynamic. The final objective was to improve the Manila clam fishing...

Autores: Bachere, Evelyne; Mialhe, Eric; Noel, Thierry; Boulo, Viviane; Hervio, Dominique; Le Gall, Ghyslaine; Morvan, Annie.
Because of the impact of infectious diseases in marine mollusc aquaculture, research has been initially developed in pathology in term of epidemiology and diagnosis. The establishment of basic techniques for in vitro and in vivo studies of host/pathogen interactions and the progresses in the field of cellular and molecular biology have permitted to undertake researches in immunology. Parallel to fundamental interest in understanding defense mecanisms of molluscs against pathogens, applications may be expected for resistant strains obtained by genetic engineering.

Genomics and mollusc pathogens: trends and perspective
Provedor de dados: 5
Autores: Renault, Tristan.
Global mollusc production is continuously increasing and reached 12.8 million tonnes in 2004 representing 28.2 percent of the total world production valued at US$ 9.4 billions. However, cultivated molluscs may suffer from severe mortality outbreaks. Among the possible causes is the occurrence of infectious diseases due to a variety of pathogens including protozoan parasites, bacteria and viruses. Preventing and controlling diseases has become a priority for aquaculture sustainability. However, molluscs are unique in terms of health management. Molluscs like other invertebrates, lack a true adaptative immune system. Vaccination can not be used to protect them against pathogens. Moreover, molluscs are usually reared in the open sea which strongly limits the...

The degradation in the quality of silver eel and their health could have been a major factor in the collapse of the European eel (Anguilla anguilla) population. However, the health status of the spawners has been poorly studied until now. This study evaluated the quality of migrant male silver eels from four Mediterranean habitats in France presenting different degrees of contamination: Canet-Saint-Nazaire, Salses-Leucate and Bages-Sigean lagoons and La Berre River. We considered pathogens including Anguillicoloides crassus and EVEX virus and the concentration of chemical contaminants including PCBs, OCs and heavy metals. Our study results revealed different patterns of pollution and infection in the four habitats, with high individual variability. No...

Removing chaos from confusion: assigning names to common human and animal pathogens in Neocosmospora
Provedor de dados: 16
Autores: Sandoval-Denis, M.; Crous, P.W.
The genus Neocosmospora encompasses highly prevalent and aggressive human and animal fungal pathogens. Here we assign formal descriptions and Latin binomials to some of the most clinically relevant phylogenetic species of the genus. Three new species, named Neocosmospora catenata, N. gamsii and N. suttoniana (previously assigned to the informal names ‘Fusarium’ solani species complex (FSSC) lineages, FSSC 43, FSSC 7 and FSSC 20, respectively) are described on the basis of multilocus phylogenetic analyses (using EF-1α, ITS, LSU and RPB2 loci) and morphological characters. Lineage FSSC 9 is conspecific with the ex-type strain of Cylindrocarpon tonkinense, thus the new combination Neocosmospora tonkinensis is proposed. In addition, and based on the latest...

The different serotyping systems, based on thermostable O antigens, reported for &lt;i&gt;Vibrio anguillarum&lt;/i&gt; and &lt;i&gt;V. ordalii&lt;/i&gt; 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 &lt;i&gt;V. anguillarum&lt;/i&gt; (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...

Provedor de dados: 27
Autores: Pedersen, K.; Grisez, L.; van Houdt, R.; Tiainen, T.; Ollevier, F.P.; Larsen, J.L.
The present paper summarizes the serotyping scheme of the fish pathogenic bacterium &lt;i&gt;Vibrio anguillarum&lt;/i&gt; and defines seven additional O-serogroups. Strains, collected in our laboratories that were nontypable with antisera against the previously defined 16 O-serotypes, were used for generating new antisera and were characterized further by means of LPS profiles, Western blots, and serological reactions. On the basis of the results, it is suggested that the seven new O-serogroups are to be included in the existing serotyping system as serotypes O17-O&lt;sub&gt;2&lt;/sub&gt;3. However, the existence of further &lt;i&gt;V. anguillarum&lt;/i&gt; strains that were not typable with any of the 23 O-antisera suggested the existence of additional...

ANTIMICROBIAL DRUG USE AND VETERINARY COSTS IN U.S. LIVESTOCK PRODUCTION
Provedor de dados: 31
Autores: Mathews,   Kenneth H., Jr.
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...

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...

Autores: Kahraman,Tolga; Issa,Ghassan; Bingol,Enver Baris; Kahraman,Beren Basaran; Dumen,Emek.
The effect of rosemary (Rosmarinus officinalis L.) essential oil (REO) and modified-atmosphere packaging (MAP) on the survival of certain pathogens (Salmonella Typhimurium and Listeria monocytogenes) in poultry fillets and on their meat quality during 7 days of refrigerated storage were investigated. Because REO at 0.05% and 0.1% had weak antibacterial activity and REO at 0.3%, 0.5% and 1.0% imparted unacceptable organoleptic properties, only REO at 0.2% was used to treat the poultry meat. The results showed that adding 0.2% REO to poultry fillets did not reduce the size of the population of S. Typhimurium and L. monocytogenes. However, REO treatment significantly decreased the L* (lightness) value and increased the a* (redness) value of stored fillets,...

ABSTRACT Fresh produce is a generalized term for a group of farm-produced crops, including fruits and vegetables. Organic agriculture has been on the rise and attracting the attention of the food production sector, since it uses eco-agricultural principles that are ostensibly environmentally-friendly and provides products potentially free from the residues of agrochemicals. Organic farming practices such as the use of animal manure can however increase the risk of contamination by enteric pathogenic microorganisms and may consequently pose health risks. A number of scientific studies conducted in different countries have compared the microbiological quality of produce samples from organic and conventional production and results are contradictory. While...

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...
