Using the fungus Arthrobotrys cladodes var. macroides as a sustainable strategy...
Oliveira, Isabela de Castro; Carvalho, Lorendane Millena de; Vieira, Ítalo Stoupa; Campos, Artur Kanadani; Freitas, Samuel GalvãoResearch in the area of sanitation in ruminant production has focused on discovery of potential agents for biological control of helminths with nematophagous fungi and has provided evidence of success. The antagonistic potential of the fungus Arthrobotrys cladodes var. macroides on infective larvae of bovine gastrointestinal parasitic nematodes was evaluated by scanning electron microscopy. Additionally, an in ...

Oliveira, Isabela de Castro; Vieira, Ítalo Stoupa; Carvalho, Lorendane Millena de; Campos, Artur Kanadani; Freitas, Samuel GalvãoBiological control through the use of nematophagous fungi is a sustainable alternative for combatting helminthes in domestic animals and allows a reduction in the use of anthelmintics. The objective of this research was to evaluate the efficacy of the Arthrobotrys cladodes var macroides fungus in a pelleted formulation, based on sodium alginate and administered twice a week orally, as an alternative for the bio...
Producción de conidios y clamidosporas de los hongos Duddingtonia flagrans y Mo...
Silva, Manoel Eduardo da; Braga, Fábio Ribeiro; Borges, Luana Alcântara; Oliveira, Paulo de; Lima, Walter dos Santos; Araújo, Jackson Victor deAs espécies Duddingtonia flagrans e Monacrosporium thaumasium são microfungos considerados promissores agentes de controle biológico de parasitos. Sob condições adversas, como a falta de nutrientes, estes fungos produzem esporos capazes de sobreviverem após a passagem pelo trato gastrintestinal dos animais. A formação destas estruturas é uma característica desejável, já que promove a sobrevivência fúngica e a s...
Nematicide activity of microfungi (Orbiliales, Orbiliaceae) after transit throu...
Silva, Manoel Eduardo da; Silveira, Wendeo Ferreira da; Braga, Fábio Ribeiro; Araújo, Jackson Victor deParasitas são comuns em sistemas intensivos avícolas ou orgânicos, mais propício para o surgimento de parasitas gastrointestinais, favorecido pelo contato direto dos animais com o solo e outros organismos. O aumento da demanda por proteína animal estimula a expansão dos sistemas de produção com aumento da densidade animal. Sistemas de criação livres (orgânicos ou não) com baixa densidade e alto padrão tecnológi...
Coadministration of sodium alginate pellets containing the fungi Duddingtonia f...
Tavela, Alexandre de Oliveira; Araújo, Jackson Victor de; Braga, Fábio Ribeiro; Silveira, Wendeo Ferreira da; Silva, Vinicius Herold Dornelas eThe predatory nematophagous fungi have been used as an alternative control of gastrointestinal nematodes of domestic animals in natural and laboratory conditions. However, it is unclear if the association of some of these species could bring some kind of advantage, from a biological standpoint. In this context, this study consisted of two tests in vitro: in assay A, the assessment of the viability of the associ...
Biological control of Ascaris suum eggs by Pochonia chlamydosporia fungus
Ferreira, Sebastião Rodrigo; Araújo, Jackson Victor de; Braga, Fábio Ribeiro; Araujo, Juliana Milani; Frassy, Luiza Neme; Ferreira, Aloízio SoaresAscaris suum is a gastrointestinal nematode parasite of swines. The aim of this study was to observe Pochonia chlamydosporia fungus on biological control of A. suum eggs after fungus passage through swines gastrointestinal tract. Eighteen pigs, previously dewormed, were randomly divided into three groups: group 1, treated with the fungus isolate VC4; group 2, treated with the fungus isolate VC1 and group 3 did ...
Biological control of cyathostomin (Nematoda: Cyathostominae) with nematophagou...
Tavela, Alexandre de Oliveira; Araújo, Jackson Victor; Braga, Fábio Ribeiro; Silva, André Ricardo; Carvalho, Rogério Oliva; Araujo, Juliana MilaniHorses are hosts to a wide variety of helminthes; the most important are the cyathostomin, or small strongyles. The viability of a fungal formulation (pellets) using the nematode- trapping fungus Monacrosporium thaumasium was assessed in biological control of horse cyathostomin. Two groups (fungus-treated and control) consisted of six mares in each group, crossbred (ages of 2.5 and 3.5 years), were placed in pa...
Controle biológico de nematodioses intestinais de equinos por fungos nematófagos
Braga, Fábio RibeiroCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; With the aim of: testing a pellet formulation in sodium alginate containing Duddingtonia flagrans (isolate AC001) mycelial fungus for biological control cyathostomins of horses raised in field, evaluate in vitro effect of D. flagrans (isolate AC001), Monacrosporium thaumasium (isolate NF34a) and P. chlamydosporia (isolates VC1 and VC4) on Oxyuris equi...
Ação in vitro de fungos das espécies Duddingtonia flagrans, Monacrosporium sine...
Braga, Fábio RibeiroCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; The in vitro effects of four isolates of the nematophagous fungi Duddingtonia flagrans (AC001), Monacrosporium sinense (SF53) and Pochonia chlamydosporia (VC1 and VC4) on eggs of Fasciola hepatica and Schistosoma mansoni was evaluated in two assays (A and B). Eggs of F. hepatica (assay A) and S. mansoni (assay B) were incubated in Petri dishes with 2%...
