13. Nematode larvae infecting Priacanthus arenatus Cuvier, 1829 (Pisces: Teleostei) in Brazil
Entre julho e dezembro de 2013, foram adquiridos 30 espécimes de Priacanthus arenatus comercializados nos municípios de Niterói e Rio de Janeiro, no estado do Rio de Janeiro. Os peixes foram necropsiados e filetados para investigação da presença de larvas de nematoides. Do total, 20 (66,7%) peixes estavam parasitados com larvas de nematoides. Foram col

14. In vitro predatory activity of conidia of fungal isolates of the Duddingtonia flagrans on Angiostrongylus vasorum first-stage larvae
INTRODUCTION: Angiostrongylus vasorum is a nematode that parasitizes molluscs, dogs, and even man. METHODS: The objective was to evaluate the predatory activity of the conidia of two fungal isolates of Duddingtonia flagrans (AC001 and CG722) on first-stage larvae (L1) of A. vasorum in laboratory conditions. RESULTS: At the end of the experiment, there were s

15. Angiostrongylus cantonensis (Nematode: Metastrongyloidea) in molluscs from harbour areas in Brazil
Angiostrongylus cantonensis is the most common aetiological agent of human eosinophilic meningoencephalitis. Following a report indicating the presence of this parasite in Brazil in 2007, the present study was undertaken to investigate the presence of A. cantonensis in the surrounding Brazilian port areas. In total, 30 ports were investigated and the followi

16. Proteolytic activity in the adult and larval stages of the human roundworm parasite Angiostrongylus costaricensis
Angiostrongylus costaricensis is a nematode that causes abdominal angiostrongyliasis, a widespread human parasitism in Latin America. This study aimed to characterize the protease profiles of different developmental stages of this helminth. First-stage larvae (L1) were obtained from the faeces of infected Sigmodon hispidus rodents and third-stage larvae (L3)

17. Helmintos oxiuridae parasitos de Iguana iguana (Squamata, Lacertilia, Iguanidae) procedentes do Brasil
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

18. Resistência anti-helmíntica em rebanhos caprinos no estado do Ceará.
Goats of 45 farms in the State of Ceará, Brazil, were treated with anthelmintics for gastrointestinal nematodes, and their resistance to the anthelmintics was evaluated. On each farm 30 kids were weighed, ear-tagged and divided into three groups of ten. The first group received oxfendazofe at 4.75mg/kg, the second levamisole at 7.5mg/kg, and the third group

19. Use of heterologous antigens for the immunodiagnosis of abdominal angiostrongyliasis by an enzyme-linked immunosorbent assay
Angiostrongylus costaricensis has a broad geographic distribution spanning from North to South America and the infections of vertebrates with this nematode can result in abdominal complications. Human infections are diagnosed by histological or serological methods because the isolation of larvae from feces is not feasible, as most parasites become trapped in

20. Treatment with mebendazole is not associated with distal migration of adult Angiostrongylus costaricensis in the murine experimental infection
Abdominal angiostrongyliasis is a zoonotic infection produced by a metastrongylid intra-arterial nematode, Angiostrongylus costaricensis. Human accidental infection may result in abdominal lesions and treatment with anti-helminthics is contra-indicated because of potential higher morbidity with excitement or death of worms inside vessels. To evaluate the eff

21. Avaliação de parâmetros limnológicos, parasitas, bactérias e metais pesados em água superficial no córrego Ribeirão Preto, Ribeirão Preto - SP / Evaluation of limnological parameters, parasites, bacteria and heavy metals in superficial water of Ribeirão Preto Stream, Ribeirão Preto-SP.
Water is fundamental to life. Its multiple uses are needed for a broad spectrum of human activities, among which stand out, the public and industrial supply, agricultural irrigation, the production of electricity and leisure activities and recreation. It is known that Brazil still has a privileged position of water quantity and quality, but their use hasnt b

22. PREDATORY ACTIVITY OF THE FUNGUS Duddingtonia flagrans ON INFECTIVE LARVAE OF STRONGYLES PARASITES OF HORSES IN PASTURE IN SOUTH BRAZIL / ATIVIDADE PREDATÓRIA DO FUNGO Duddingtonia flagrans SOBRE LARVAS INFECTANTES DE ESTRONGILÍDEOS PARASITOS DE EQUINOS NA PASTAGEM NO SUL DO BRASIL
Biological control is an alternative method used to reduce the population of parasites through natural antagonist. A promising option of biological control to reduce infective larvae in pasture is the use of nematophagous fungus. The efficacy of the nematophagous fungus Duddingtonia flagrans was tested to control gastrointestinal nematode parasites of horses

23. Fernandes, Ana Rosa de Figueiredo. Pathogenicity of Pratylenchus brachyurus and severity of bacterial wilt in association with this nematode in tobacco. 2009. / Fernandes, Ana Rosa de Figueiredo. Patogenicidade de Pratylenchus brachyurus e severidade da murcha bacteriana quando associada a este nematóide em fumo. 2009.
The pathogenicity of Pratylenchus brachyurus on tobacco (Nicotiana tabacum) cultivar K326 was evaluated in experiments testing different initial population densities of the nematode (Pi = 0; 1,000; 3,000; 9,000 and 27,000 eggs and larvae per plant), in eight replications. The isolate was monoxenically multiplied on carrot discs. At the end of the exp

24. Uso de águas residuárias tratadas na cultura de hortaliças: avaliação de enteroparasitas e metais pesados / The use of treated residuary water to grow vegetables: assessment of enteroparasites and heavy metals.
Water shortage is a worldwide problem, and the use of residuary water is an important theme regarding the preservation of water bodies and conscious use of the resources available. This study aimed to evaluate the viability of using treated residuary water from the Biological Wastewater Treatment Plant of Ribeirão Preto (ETE-RP) to grow vegetables, through
