| ABSTRACTCongeneric host species present similar biological and behavioral aspects, what may favor the presence of a similar parasite fauna. The aim of the present study was to compare the composition and structure of the parasite community from congeneric species, Brycon amazonicus and B. melanopterus, collected on the Negro and Solimões Rivers. The fish internal organs were longitudinally opened and analyzed under stereomicroscope. The examination revealed that B. amazonicuswas parasitized by Procamallanus(Spirocamallanus) inopinatus(26.7% and 35.5%), Contracaecum type 2 (10% and 16.13%) and Rhabdochona acuminata(0% and 3.23%), prevalence values for Negro and Solimões River, respectively. The analysis of B. melanopterus, a fish species found only in the... |

| O uso de híbridos e genótipos de milho resistentes aos nematóides formadores de galhas em sistemas de rotação de culturas mantém sua população em níveis baixos, diminuindo as perdas e possibilitando, posteriormente, o uso de genótipos mais suscetíveis. No presente trabalho, foi avaliada a resistência de 18 genótipos de milho ao parasitismo de M. paranaensis e a M. incógnita raça 1 em casa-de-vegetação. As plantas foram inoculadas com 5.000 ovos e eventuais juvenis dos respectivos nematóides. O delineamento utilizado foi inteiramente ao acaso, com dez repetições para cada tratamento com os nematóides e cinco repetições para a testemunha sem inoculação. Também foi realizada a técnica de coloração das raízes com fucsina ácida, pelo método de Byrd et al.... |

| The accuracy of the FAMACHA© method was evaluated on the identification of female sheep fed two levels of crude protein, naturally infected with Haemonchus contortus, by means of the correspondent hematocrit value. Forty-seven female sheep of the breeds Santa Inês (n = 16), Texel (n = 16) and Ile de France (n = 15) aged between eight and twelve months were assigned to two treatments, 12 or 16 % crude protein in the diet. All the animals were wormed thirty days before the first data collections, which were done fortnightly between July 2005 and March 2006. The color of the ocular conjunctiva was individually evaluated according to the precepts of the FAMACHA© method and the hematocrit value of each animal was obtained in laboratory. A correlation of... |

| The study analyzed 84 specimens of Metynnis lippincottianus (Cope, 1870) (Characidae) from two environments with different degrees of impact due to a hydroeletric plant; 44 hosts from the upper Parana river floodplain (low degree of impact) and 40 from Paranapanema tributaries (Corvo and Guairacá rivers, high degree of impact). The prevalence found, among the total collected fishes, was 77.4%. One digenetic species, Dadayus pacupeva, and four nematodes, Spinoxyuris oxydoras, Contracaecum sp. (larval stage), Procamallanus (Spirocamallanus) inopinatus and Raphidascaris (Sprentascaris) mahnerti were identified. In the floodplain, the fishes parasitized by D. pacupeva and S. oxydoras presented better relative condition factor (Kn) than non-parasitized species.... |

| 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 present study describes Camallanus maculatus n. sp. (Nematoda: Camallanidae) from Xiphophorus maculatus (Osteichthyes: Poecilidae) collected in an ornamental fish farm in São Paulo State, Brazil. Thirty-three out of 40 examined fish were parasitized (82% prevalence) with mean intensity of 2.8 (1-20). Male specimens were 3,500µm total length and females 7,100µm total length, provided with orange-brown buccal capsule and two developed tridents. Males showed two unequal spicules, gubernaculum absent and females with vulva situated in the middle of the body. The main characteristics were the sleekly longitudinal ridges in the buccal capsule in both sexes, enlargement at the anterior end of the smaller spicule, the number of genital papillae, longer... |

| ABSTRACT Stephanofilariasis is an ulcerative dermatitis caused by nematodes that affect cattle in several countries in the world. However, it has not been described in beef cattle in Brazil. The objective of this study is to describe three cases of stephanofilariasis, which occurred in beef cows in the municipality of Ipê, RS, Brazil. The disease was characterized by pruritic, ulcerated and crusty seasonal lesions present in the cranial region of the udder. The diagnosis was confirmed by analyses of secretions stained smears and by direct optical microscopic examination of the sediment and the treatment was effectively carried out with topical trichlorphon. This report indicates that stephanofilariasis should be included as a differential diagnosis 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... |

| 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,... |

| 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... |
