Los parásitos helmintos producen y secretan una gran variedad de proteínas que unen lípidos (LBPs, del inglés lipid binding proteins) que podrían participar en la obtención de nutrientes tales como ácidos grasos y colesterol desde el hospedador. Asimismo, se postula que las LBPs podrían intervenir en la regulación de la respuesta inmune del hospedador. Conocer más acerca de las estructuras de estas proteínas, así como de sus interacciones con ligandos y membranas, es claramente pertinente para comprender las interacciones parásito-hospedador que ellas pudieran mediar. Por otra parte, dichos estudios permitirán profundizar en el conocimiento de los mecanismos de infección helmíntica y en el papel que estas proteínas juegan en la biología de los helmintos en... |

A fin de evaluar la contaminación con huevos de Toxocara de los suelos de espacios públicos destinados a recreación y relacionarla con las características urbanas y geográficas de la ciudad, se recolectaron 612 muestras de suelo de las áreas destinadas al juego infantil de 6 plazas, 4 parques y 34 plazoletas de la ciudad de Resistencia (Provincia del Chaco, Argentina) que se procesaron por triplicado por el método de flotación en una solución saturada de ClNa. Se encontraron huevos de Toxocara spp. en el 33,3% de las plazas, en el 25,0% de los parques y en el 20,6% de las plazoletas. En el 61,5% de las muestras positivas los huevos estaban embrionados o en proceso de división, correspondiendo a 5 muestras procedentes de las plazas, 3 de los parques y 8 de... |

The results of a study on nematode fauna occurring in wild iguanas (Iguana iguana) from Brazilian Northeast (Alagoas and Maranhão) and Central-west (Goiás and Mato Grosso) areas were presented. Six adult iguanas, three males and three females, were necropsied and the digestive system removed to examination. All the iguana specimens were heavily parasitized. The helminths diagnosed were: Ozolaimus cirratus in the cecum and colon of five iguanas; Ozolaimus megatyphlon in cecum, colon and rectum of three iguanas; and Alaeuris vogelsangi in the small intestine, cecum, colon and rectum of five animals. Two larvae of Ozolaimus sp. were recovered from the pyloric region of the stomach of one iguana. The three diagnosed species of nematodes were reported for the... |

The gastric compartments of ten cetaceans stranded on the coast of Ceará State, Northeast Brazil were analyzed in this study. Gastric Anisakis spp. was diagnosed in all individuals involved in this study. Parasites and tissue samples were collected during necropsy. The presence of Anisakis parasites showed similar distribution across the three gastric compartments and the majority was free within the gastric lumen. Macroscopically, the lesions were predominantly characterized by the presence of ulcers (60%, 6/10) within the gastric mucosa, occasionally associated with edema and hemorrhage (30%, 3/10). Eight cetaceans (8/10 - 80%) presented gastric microscopic alterations and in 75% (6/8) of these animals, chronic lymphoplasmocytic gastritis was observed... |

Lifecycle of phytoparasitic nematode takes place in the rhizosphere, therefore their breeding, parasitism and mobility dynamics are inevitably influenced by the soil-root interaction, A study was performed to evaluate the influence of Vitis rootstocks to some plant parasitic nematodes under different soil conditions. Nematode populations were assessed in Vitis vinifera L. var Chardonnay plants grafted on two rootstocks (K5BB, SO4) and ungrafted Chardonnay as a control in three diferent alluvial soils in the central zone of Chile. Soils were two Inceptisols of the Casablanca Valley (Valparaíso Region), the first one without soil structure and with a densification zone in depth (S1) and the second one with sandy textural class (S3). A third soil was a... |

The biological control of the root-knot nematode, Meloidogyne hapla , was evaluated through the addition of organic amendments of dry and chopped leaves of Buddleia globes, Dramas winter, Eucalyptus globules, Genuine aflame, Aurelia sempervirens, huma apiculata, Maytenus boaria and Ugni molinae to the soil substratum. The assays were carried out in pots seeded with lettuce plants (cv. Reina de Mayo). All pots were inoculated with 2000 eggs and juveniles of M. hapla, and then maintained under greenhouse conditions for 45 days. Control pots without foliage additions were also seeded with lettuce. The results show that the addition of dry leaves of L. sempervirens, G. avellana, M. boaria, D. winteri , and B. globosa significantly reduced root-knot nematode... |

The viability of a formulation of the fungus Monacrosporium thaumasium associated with ivermectin was evaluated for the biological control of bovine gastrointestinal nematode parasites. Four groups of five calves each were placed in pastures with a stocking rate of 1.6 animal/hectare. In group 1 (control), the calves did not receive any treatment. In group 2, each animal received 20g of pellets of M. thaumasium orally twice a week during a six-month period that began with the onset of the rainy season (October 23, 2000). In group 3, each animal received 20g of pellets of M. thaumasium orally twice a week during the same period as 2, as well as two strategic treatments with ivermectin (200 mcg/kg) on May 10, 2001 and July 5, 2001. In group 4, the animals... |

The aim of this study was to evaluate the potential uses of acacia extract (AE) on Trichostrongylus colubriformis control in sheep. The lambs were allocated in three groups of six animals. Two groups were experimentally infected with third-stage larvae of T. colubriformis and one was remained as non-infected control. Thirty days post-infection, the infected animals from treated group were supplemented with AE. During and after the treatment, the values of faecal eggs counts (FEC), number of third-stage larvae recovered per gram of faeces (LPG), number of FEC accumulated per animal during the treatment period, nematode egg viability, and worm burden were determined. Animals from non-infected group did not presented FEC values, during the experimental... |

Con el objetivo de determinar las cargas parasitarias y su impacto en el rendimiento de la canal de ovinos de pelo. Se analizó el contenido gastrointestinal de 122 animales provenientes de diferentes municipios del estado de Tabasco como: Centro, Emiliano Zapata, Frontera, Huimanguillo, Teapa y de Reforma, Chiapas. El estudio se realizó en un rastro de Villahermosa en los meses de enero a julio de 2011. Del total de animales estudiados 58 fueron hembras y 64 machos. Se utilizó el procedimiento GLM del SAS para analizar los conteos de nematodos adultos totales y por especie respecto al origen, edad, sexo, estado fisiológico, color del pelaje y mes de muestreo. Para analizar el efecto de la parasitosis y los factores genéticos y ambientales sobre el... |

El objetivo de este estudio fue evaluar la patogenicidad de los nematodos, Heterorhabditis sp. (CPVG13) y Steinernema spp. (CPVC12, CPVC13) sobre el salivazo, Aeneolamia albofasciata y determinar su persistencia en suelo de tres ingenios azucareros Potrero, Constancia y Motzorongo, en el estado de Veracruz. En el primer experimento la patogenicidad de los nematodos entomopatógenos se evaluó en ninfas de mosca pinta, Aeneolamia albofaciata de 3° y 4° instar, se aplicaron 120 JI/ninfa sobre cajas con seis cavidades, cubiertas previamente con papel filtro, cada cavidad contenía un estolón de pasto (Cynodon sp.) y una ninfa por cavidad. En el segundo experimento, se evaluó la persistencia de los nematodos entomopatógenos (NEPs) en suelo, el experimento tuvo... |

O feijão-de-vagem é uma hortaliça severamente atacada por Meloidogyne javanica quando cultivada após o tomate-salada. Para avaliar a viabilidade de cultivo do feijão-de-vagem após o tomate-salada, cultivou-se a Crotalaria spectabilis, em faixas, por período de quatro meses, previamente ao cultivo do tomateiro. Faixas cultivadas com quiabeiro, antes do cultivo com tomate-salada, foram mantidas para comparação. Nas faixas cultivadas anteriormente com C. spectabilis, com os índices de multiplicação (IM) variando de 11 a 76 por parcela e os números de ovos do nematóide de 1.500 a 6.000 por planta, as produtividades foram de 2 a 26% maiores em cultivares de tomateiro e de 6 a 31,5% maiores em cultivares de feijão-de-vagem, em comparação com as produtividades... |
