In vitro biological control of infective larvae of Ancylostoma ceylanicum.

The aim of this study was to evaluate the predatory activity of the fungus Duddingtonia flagrans (AC001) on infective larvae of Ancylostoma ceylanicum after gastrointestinal transit in hamsters. Twenty animals were used in the experiment, divided into two groups: a treated group (10 animals) and a control group (10 animals). In the group treated with D.

[Destruction of Strongyloides venezuelensis infective larvae by fungi Duddingtonia flagrans, Arthrobotrys robusta and Monacrosporium sinense].

Introduction: Strongyloides venezuelensis has been used as a model for studying human strongyloidosis.

Methods: This study aimed to compare the ability of predatory nematophagous fungi Duddingtonia flagrans (AC001), Arthrobotrys robusta (I-31) and Monacrosporium sinense (SF53) and on infective larvae (L3) of Strongyloides venezuelensis in laboratory conditions on 2% water-agar medium.

Results: At the end of the experiment, the percentage reductions of Strongyloides venezuelensi L3 were: 93% (AC001), 77.

[Ovicidal action of a crude enzymatic extract of fungus Pochonia chlamydosporia against Ancylostoma sp eggs].

Introduction: Ancylostoma sp is a potentially zoonotic geohelminth.

Methods: This study aimed to evaluate in vitro the action of crude enzyme extract of Pochonia chlamydosporia (VC4) on eggs of Ancylostoma sp in 2% water-agar and in fecal cultures.

Results: The percentage reduction in Ancylostoma sp egg eclosion was 76.

Viability and nematophagous activity of the freeze-dried fungus Arthrobotrys robusta against Ancylostoma spp. infective larvae in dogs.

Viability and in vitro and in vivo activities of freeze-dried conidia of the predatory fungus Arthrobotrys robusta (I-31) were evaluated against infective larvae (L(3)) of Ancylostoma spp. in dogs. A.

[Predatory activity of the nematophagous fungi Duddingtonia flagrans, Monacrosporium thaumasium and Arthrobotrys robusta on Strongyloides stercoralis infective larvae].

Introduction: Strongyloides stercoralis is a nematode that infects much of the population worldwide.

Methods: This study aimed to compare the ability of predatory nematophagous fungi Duddingtonia flagrans (AC001), Monacrosporium thaumasium (NF34) and Arthrobotrys robusta (I-31) on infective larvae (L₃) of Strongyloides stercoralis in laboratory conditions on 2% water-agar.

Results: At the end of the experiment, the percentage reductions in Strongyloides stercoralis L3 were 83.

Biological control of cyathostomin (Nematoda: Cyathostominae) with nematophagous fungus Monacrosporium thaumasium in tropical southeastern Brazil.

Horses 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.

Ovicidal action of a crude enzymatic extract of the fungus Pochonia chlamydosporia against cyathostomin eggs.

The aims of this study were to test the action of the fungal extract of Pochonia chlamydosporia (VC4) on the hatching of cyathostomin eggs plated in Petri dishes containing 2% water-agar (2% WA) and its enzymatic activity in fecal cultures, in two experimental assays (A and B). The fungus P. chlamydosporia (VC4) was cultured in Erlenmeyer flasks (250ml) containing 50ml of liquid minimal medium supplemented with 0.

Viability of the nematophagous fungus Pochonia chlamydosporia after passage through the gastrointestinal tract of horses.

The predatory capacity of the nematophagous fungus Pochonia chlamydosporia (isolate VC4) embedded in sodium alginate pellets after passage through the gastrointestinal tract of horses was assessed in vitro against Oxyuris equi eggs. Twelve previously dewormed crossbred mares, average weight of 362.5kg (+/-21) were used in the experiment.

Activity of the nematophagous fungi Pochonia chlamydosporia, Duddingtonia flagrans and Monacrosporium thaumasium on egg capsules of Dipylidium caninum.

Nematophagous fungi are potential biological control agents of helminths. The in vitro ovicidal effect of four isolates of the nematophagous fungi Pochonia chlamydosporia (VC1 and VC4), Duddingtonia flagrans (AC001) and Monacrosporium thaumasium (NF34) was evaluated on egg capsules of Dipylidium caninum, a cestode parasite of dogs, cats and humans. One thousand egg capsules of D.

Biological control of horse cyathostomin (Nematoda: Cyathostominae) using the nematophagous fungus Duddingtonia flagrans in tropical southeastern Brazil.

The viability of a fungal formulation using the nematode-trapping fungus Duddingtonia flagrans was assessed for the biological control of horse cyathostomin. Two groups (fungus-treated and control without fungus treatment), consisting of eight crossbred mares (3-18 years of age) were fed on Cynodon sp. pasture naturally infected with equine cyathostome larvae.

[Effect of the fungus Paecilomyces lilacinus on Taenia saginata eggs].

With the aim of demonstrating the effectiveness of the fungus Paecilomyces lilacinus on Taenia saginata eggs under laboratory conditions, a trial was set up in Petri dishes with water-agar 2%. There was ovicidal activity (p < 0.05) in relation to the control group on the tenth day of interaction and an internal colonization rate of 25.
