| In this survey 1,500 samples of nematodes, representing 151 species, distributed in 20 superfamilies, parasitizing Brazilian mammals (Artiodactyla, Carnivora, Chiroptera. Edentata, Lagomorpha, Marsupialia, Perissodactyla, Primates, Rodentia) and deposited between 1916-1963 in the CHIOC were studied. New host records were established for 52 Parasite species distributed in 15 superfamilies, adding new data to previous reports of mammalian nematodes in Brazil. |

| 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... |

| 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... |

| In submarine canyon sediments, bacteria and nematodes dominate the benthic biomass and play a key role in nutrient cycling and energy transfer. The diversity of these communities remains, however, poorly studied. This work aims at describing the composition of bacteria and nematode communities in the Lacaze-Duthiers submarine canyon in the north-western Mediterranean Sea. We targeted three sediment depths for two consecutive years and investigated the communities using nuclear markers (18S rRNA and 16S rRNA genes). High throughput sequencing combined to maximal information coefficient (MIC) statistical analysis allowed us to identify, for the first time, at the same small scale, the community structures and the co-occurrence of nematodes and bacteria... |

| 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... |

| 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... |
