Biodesinfección del suelo y uso de Pochonia chlamydosporia en el manejo de Meloidogyne arenaria en el cultivo de guayabo en el oriente de Michoacán.
Provedor de dados: 32
Autores: Torres López, Japhet.
El objetivo de esta investigación fue estudiar la respuesta de los árboles de guayabo al tratamiento con diferentes abonos orgánicos y la incorporación del hongo nematófago Pochonia chlamydosporia y el efecto en la reducción de juveniles (J2) de Meloidogyne arenaria. Se tomaron muestras de suelo infestados con el nematodo en la región guayabera oriente del estado de Michoacán, México. Se obtuvieron dos aislamientos  de Pochonia chlamydosporia var. chlamydosporia provenientes de raíz y suelo. Se obtuvieron in vitro los aislamientos, de raíz que parasitó 89 % huevos de Meloidogyne sp. y el aislamiento de suelo parasitó 83% con una producción de 18 x 107 •g-1 y 11 x 107 •clamidosporas/g-1 respectivamente. Se aplicaron 13.5 kg, 42 kg y 13.5 kg de gallinaza,...

Construction and expression of aspartic protease from Onchocerca volvulus* as ompA fusion protein in a mutant strain of Salmonella typhimurium
Provedor de dados: 74
Autores: Jolodar,Abbas; Miller,David J.
Two constructions in pHS164 vector were designed to permit expression of OV7A and OV4A inserts encoding the N-terminal and C-terminal portion of an aspartic protease from Onchocerca volvulus, respectively. A novel 39 kD protein ompA-OV7A fusion protein was stably expressed as ompA fusion in a modified strain of Salmonella typhimurium strain SL5000 and E.coli strain JM109. Expression of the fusion protein in bacterial strains harboring the constructs were evaluated by western blotting. E.coli and Salmonella lysates were fractionated by 10% SDS-PAGE gel and then immobilized to nitrocellulose membrane by electroblotting. Primary polyclonal antibody generated in rats against the GST-OV7A fusion protein was used in the Western blots. It remains to be seen...

Devenir des bactéries dans les réseaux trophiques des vasières intertidales : le cas de brouage (Baie de Marennes-Oléron)
Provedor de dados: 5
Autores: Pascal, Pierre-yves.
Bacteria are highly abundant and productive in intertidal mudflat sediments. By analogy  with pelagic system, it has been suggested that bacteria play an important role in benthic food  web. Due to technical difficulties, numbers of studies dealing with benthic bacterivory are not  numerous and give conflicting results. A method using community of 15N enriched bacteria as  tracer was developed in order to measure grazing of meiofauna and macrofauna. Since enriched  bacteria present characteristics of size, activity and diversity close to natural ones, bias due to  selective bacterial ingestion by grazers are limited. Due to tidal cycles, intertidal mudflat  constitutes highly variable environment at short time scale. Since those variations may influence...

Trophic role of large benthic sulfur bacteria in mangrove sediment
Provedor de dados: 5
Autores: Pascal, Pierre-yves; Dubois, Stanislas; Boschker, Henricus T. S.; Gros, Olivier.
Large filamentous sulfur-oxidizing bacteria belonging to the Beggiatoacae family can cover large portions of shallow marine sediments surrounding mangroves in Guadeloupe (French West Indies). In order to assess the importance of Beggiatoa mats as an infaunal food source, observations were conducted of the area within mats and at increasing distances from mats. We used natural isotopic compositions and a C-13 enrichment study. Both revealed an ingestion of bacterial mats by associated meiofauna, dominated by rotifers and to a smaller extent by small polychaetes and nematodes. Compared to adjacent sites, sediment covered by bacterial mats presented a higher abundance of diatoms, whereas the total biomass of bacteria did not vary. This constant bacterial...

Bioindicators assess the mangroves ecological state according to the types of pressures but they differ with the ecosystem’s specificities. We investigated benthic meiofauna diversity and structure within the low human-impacted mangroves in French Guiana (South America) in response to sediment variables with various distances to the main city. Contaminant’s concentrations differed among the stations, but they remained below toxicity guidelines. Meiofauna structure (Foraminifera, Kinorhyncha, Nematoda) however varied accordingly. Nematode’s identification brought details on the sediment’s quality. The opportunistic genus Paraethmolaimus (Jensen, 1994) strongly correlated to the higher concentrations of Hg, Pb. Anoxic sediments were marked by organic...

Autores: Miljutin, Dmitry M.; Miljutina, Maria A.; Arbizu, Pedro Martinez; Galeron, Joelle.
We investigated nematode assemblages inhabiting the 26-year-old track created by experimental deep-sea mining of polymetallic nodules, and two adjacent, undisturbed sites, one with nodules and one without nodules. The aim was to compare density, assemblage structure, and diversity indices in order to assess the process of recovery of the nematode assemblage inhabiting the disturbed site. This experimental dredging was conducted in 1978 by the Ocean Minerals Company (USA) in the area of a French mining claim in the Clarion-Clipperton Fracture Zone (Tropical Eastern Pacific) at a depth of about 5000 m. The nematode assemblage had not returned its initial state 26 years after the experimental dredging: the total nematode density and biomass within the...

Microbial Communities of the Shallow-Water Hydrothermal Vent Near Naples, Italy, and Chemosynthetic Symbionts Associated With a Free-Living Marine Nematode
Provedor de dados: 5
Autores: Bellec, Laure; Cambon-bonavita, Marie-anne; Durand, Lucile; Aube, Johanne; Gayet, Nicolas; Sandulli, Roberto; Brandily, Christophe; Zeppilli, Daniela.
Shallow-water hydrothermal vents are widespread, especially in the Mediterranean Sea, owing to the active volcanism of the area. Apart free microbial communities’ investigations, few biological studies have been leaded yet. Investigations of microbial communities associated with Nematoda, an ecologically important group in sediments, can help to improve our overall understanding of these ecosystems. We used a multidisciplinary-approach, based on microscopic observations (scanning electron microscopy: SEM and Fluorescence In Situ Hybridization: FISH) coupled with a molecular diversity analysis using metabarcoding, based on the 16S rRNA gene (V3-V4 region), to characterize the bacterial community of a free-living marine nematode and its environment, the...

Petromyzon marinus (Petromyzontidae), an unusual host for helminth parasites in western Europe
Provedor de dados: 5
Autores: Gerard, Claudia; Verrez-bagnis, Veronique; Jerome, Marc; Lasne, Emilien.
The sea lamprey Petromyzon marinus, which is among the most phylogenetically ancient vertebrates, is a hematophagous ectoparasite that feeds on vertebrates and is considered vulnerable in Europe but is a pest in the North American Great Lakes. We conducted a literature review of helminth parasites of Petromyzon marinus and investigated postmetamorphic lampreys sampled in rivers and northeast Atlantic coastal waters (western France) during spawning migration. Based on the literature review, 16 helminth taxa have been recorded in Petromyzon marinus, among them 14 in North America but only 2 in Europe, with no species in common between these areas. Specific parasites are lacking, and helminth parasites recorded in Petromyzon marinus are mostly opportunistic...

Autores: Bellec, Laure; Cambon-bonavita, Marie-anne; Cueff-gauchard, Valerie; Durand, Lucile; Gayet, Nicolas; Zeppilli, Daniela.
Deep-sea hydrothermal vent meiofauna have been the focus of recent research and the discovery of an abundant well-adapted free-living marine nematode on the Mid-Atlantic Ridge offers new perspectives on adaptations to the vent environment. Indeed, knowledge concerning biological interactions of microbes and meiofauna in marine extreme environments is scarce, especially for nematodes. In this study, we used microscopic observations [fluorescence in situ hybridization (FISH) and scanning electron microscopy (SEM)] and metabarcoding of 16S rRNA to characterize the bacterial community of the nematode species Oncholaimus dyvae, an overlooked but ecologically important vent organism. Detection of bacteria in the buccal cavity and on the cuticle (SEM) and...

Bacterivory of a mudflat nematode community under different environmental conditions
Provedor de dados: 5
Autores: Pascal, P.y.; Dupuy, C; Richard, P; Rzeznik-orignac, J; Niquil, Nathalie.
The fate of the benthic bacterial biomass is a topic of major importance in understanding how softbottom environments function. Because of their high abundance, production and nutritional value, benthic bacteria may constitute an important food resource for benthic fauna. The trophic role of bacteria for a nematode community on the Brouage mudflat (Marennes-Ole´ron-France), dominated by three species: Chromadora macrolaima (64% of the abundance), Daptonema oxycerca (15%) and Ptycholaimellus jacobi (8%), was determined in grazing experiments using 15N pre-enriched bacteria. On intertidal flats, seasonal, tidal and circadian cycles induce strong variations in environmental conditions. Grazing experiments were performed in order to measure the effects of...

Microbial control of arthropod pests of tropical tree fruits
Provedor de dados: 82
Autores: Dolinski,Claudia; Lacey,Lawrence A.
A multitude of insects and mites attack fruit crops throughout the tropics. The traditional method for controlling most of these pests is the application of chemical pesticides. Growing concern on the negative environmental effects has encouraged the development of alternatives. Inundatively and inoculatively applied microbial control agents (virus, bacteria, fungi, and entomopathogenic nematodes) have been developed as alternative control methods of a wide variety of arthropods including tropical fruit pests. The majority of the research and applications in tropical fruit agroecosystems has been conducted in citrus, banana, coconut, and mango. Successful microbial control initiatives of citrus pests and mites have been reported. Microbial control of...

An Outbreak of Intestinal Obstruction by Ascaridia Galli in Broilers in Minas Gerais
Provedor de dados: 89
Autores: Torres,ACD; Costa,CS; Pinto,PN; Santos,HA; Amarante,AF; Gómez,SYM; Resende,M; Martins,NRS.
ABSTRACT Industrial broilers raised on helminthic medication-free feed were diagnosed with a severe disease caused by Ascaridia galli, characterized by intestinal hemorrhage and obstruction. A. galli was identified based on the morphological features of the nematode. Broilers were raised for a longer period (63 days) for weight recovery, grouped as stunted (n=500), had low body score and had fetid diarrhea. The duodenum-jejunum segment was the most severely affected with obstruction and had localized accumulation of gas. The intestinal mucosa was severely congested with petechial and suffusive hemorrhages. The outbreak resulted in morbidity of about 10% and mortality of up to 4% and was associated to the absence of preventive medication on feed and slack...

A new look into the small-scale dispersal of free-living marine nematodes
Provedor de dados: 103
Autores: Thomas,Micheli C; Lana,Paulo C.
We tested experimentally the hypothesis that prevailing locomotion/feeding strategies and body morphology may lead to more active dispersal of free-living marine nematodes, besides passive transport. Neutral Red was applied to the sediment inside cores and the red plume formed during the flood tide was divided into near, middle, and distant zones. At 0.5 m and 1 m from the stained cores, sampling nets were suspended 5 and 10 cm above the sediment-water interface. Dispersion behaviors were defined as a function of a) the numbers of stained recaptured nematodes in comparison to their mean densities in the sediment, b) movement in the sediment or swimming in the water column, and c) body morphology. Tidal currents with average velocities of 9 cm/s resuspended...

ABSTRACT A new species of a free-living marine nematode found in Brazil is described: Trileptium ribeirensis sp. nov. The type material is deposited in the Nematoda collection of the Museu de História Natural da Bahia, located at the Universidade Federal da Bahia. Trileptium includes eleven valid species of nematodes that have teeth and jaws positioned forward. The species was collected with the help of corers (3.5 cm in diameter and 30 cm long) on a sandy beach in Bahia. This species is distinguished from its congeners based on a combination of characters of the male (cuticle, buccal cavity, supplement and gubernaculum). An updated taxonomic key to the genus is presented.

Cross-disciplinary approaches for measuring parasitic helminth viability and phenotype
Provedor de dados: 42
Autores: Peak,Emily; Hoffmann,Karl F.
Parasitic worms (helminths) within the Phyla Nematoda and Platyhelminthes are responsible for some of the most debilitating and chronic infectious diseases of human and animal populations across the globe. As no subunit vaccine for any parasitic helminth is close to being developed, the frontline strategy for intervention is administration of therapeutic, anthelmintic drugs. Worryingly, and unsurprising due to co-evolutionary mechanisms, many of these worms are developing resistance to the limited compound classes currently being used. This unfortunate reality has led to a renaissance in next generation anthelmintic discovery within both academic and industrial sectors. However, a major bottleneck in this process is the lack of quantitative methods for...

The influence of Meloidogyne incognita and M. paranaensis on the development of mate (Ilex paraguariensis ST. Hill) plantlets was assessed in greenhouse and laboratory. The experimental design was randomized. Every plot of each one of the 10 repetitions contained one mate plantlet , inoculated with 5,000 eggs of M. incognita (races 1, 2, 3 and 4) and M. paranaensis. After 120 days it was observed that mate was a reliable hostess to such nematodes and that they could finish their life cycle. Plant development was significantly modified by M. incognita, races 1 and 2. Dry and green matter weight of shoots changed according to treatment. No changes were observed in fresh root weight. The number of eggs per root was similar for M. incognita, races 1 and 2, and...

ABSTRACT: Nematodes of the superfamily Metastrongyloidea affect the respiratory, cardiovascular, and nervous systems of domestic carnivores and are uncommonly detected in wild animals. This report describes the lesions associated with pulmonary parasitism by nematodes of the superfamily Metastrongyloidea in a wild crab-eating fox ( Cerdocyon thous ) in the Federal District, Brazil. Grossly, there was pulmonary hyperemia, edema, and emphysema. Microscopically, there was granulomatous arteritis associated with intravascular metastrongylid. The anatomical location, characteristic lesion, and histological features of the parasite suggested that the nematode involved in this case is Angiostrongylus vasorum . This worm is frequently reported parasitizing...
