1. Interaction of the nematophagous fungus Pochonia chlamydosporia on eggs of Spartocera dentiventris (Berg) (Hemiptera: Coreidae) under laboratory conditions
Resumo A doença de Chagas (DC) é considerada uma doença típica da população de baixa renda dos países em desenvolvimento da América Latina. Dada a relevância histórica da DC em indivíduos do sul do Estado do Rio Grande do Sul (RS), o objetivo deste estudo foi identificar o conhecimento da doença de Chagas (DC) e seus vetores em pacientes cardíac

2. In vitro predatory activity of nematophagous fungi isolated from water buffalo feces and from soil in the Mexican southeastern
Resumo Fungos nematófagos das fezes de búfalo de água e do solo no sudeste do México foram isolados, e a atividade predatória in vitro contra larvas infectantes de Haemonchus contortus (L3) (HcL3) foi avaliada.Os fungos foram isolados por aspersão de solo e de fezes em placas de agar água. Foram preparadas seis séries de 10 placas de Petri contendo u

3. Rhabditis spp., in the Espírito Santo, State of Brazil and evaluation of biological control
Resumo Os objetivos neste estudo foram descrever ocorrências do nematódeo Rhabditis spp., causando otite parasitária em bovinos leiteiros da raça Gir no estado do Espírito Santo, sudeste do Brasil, e avaliar o controle biológico desse nematódeo utilizando os fungos nematófagos Duddingtonia flagrans (AC001) e Monacrosporium thaumasium (NF34). Após a

4. Exposure of Toxocara canis eggs to Purpureocillium lilacinum as a biocontrol strategy: an experimental model evaluation
Resumo Purpureocillium lilacinum é um fungo nematófago com potencial para uso no controle biológico de parasitos, incluindo Toxocara canis. Este estudo pesquisou a infectividade de ovos de T. canis embrionados após exposição ao fungo P. lilacinum . Ovos de T. canis foram expostos ao fungo por 15 ou 30 dias e subsequentemente administrados a camundongos

5. 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

6. Proteases and Their Involvement in the Infection and Immobilization of Nematodes by the Nematophagous Fungus Arthrobotrys oligospora
The nematophagous fungus Arthrobotrys oligospora produced extracellular proteases when grown in a liquid culture, as revealed by measuring the hydrolysis of the chromogenic substrate Azocoll. The extracellular protease activity was inhibited by phenylmethylsulfonyl fluoride (PMSF) and other serine protease inhibitors and partly inhibited by the aspartate pro

7. Crystallization and preliminary crystallographic analysis of a chitinase from Clonostachys rosea
A chitinase from the nematophagous fungus C. rosea was overexpressed in E. coli, purified and crystallized. Diffraction data were collected to 1.8 Å resolution.

8. Quantification in Soil and the Rhizosphere of the Nematophagous Fungus Verticillium chlamydosporium by Competitive PCR and Comparison with Selective Plating
A competitive PCR (cPCR) assay was developed to quantify the nematophagous fungus Verticillium chlamydosporium in soil. A γ-irradiated soil was seeded with different numbers of chlamydospores from V. chlamydosporium isolate 10, and samples were obtained at time intervals of up to 8 weeks. Samples were analyzed by cPCR and by plating onto a semiselective med

9. Detection and Quantification of Plectosphaerella cucumerina, a Potential Biological Control Agent of Potato Cyst Nematodes, by Using Conventional PCR, Real-Time PCR, Selective Media, and Baiting
Potato cyst nematodes (PCN) are serious pests in commercial potato production, causing yield losses valued at approximately $300 million in the European Community. The nematophagous fungus Plectosphaerella cucumerina has demonstrated its potential as a biological control agent against PCN populations by reducing field populations by up to 60% in trials. The

10. Improving the Pathogenicity of a Nematode-Trapping Fungus by Genetic Engineering of a Subtilisin with Nematotoxic Activity
Nematophagous fungi are soil-living fungi that are used as biological control agents of plant and animal parasitic nematodes. Their potential could be improved by genetic engineering, but the lack of information about the molecular background of the infection has precluded this development. In this paper we report that a subtilisin-like extracellular serine
