Application of a formulation of the nematophagous fungus Duddingtonia flagrans ...
Dias, Anderson S.; Araújo, Jackson V.; Campos, Artur K.; Braga, Fabio R.; Fonseca, Thiago A.The viability of a formulation of Duddingtonia flagrans was assessed in the control of parasite gastrointestinal nematodes of cattle. Two groups (A and B) of eight crossbred Holstein × Zebu cattle, approximately one year old, were placed in Brachiaria decumbens pasture. Each animal in group B (treated) received orally 20 g sodium alginate pellets containing mycelial mass of the D. flagrans fungus, while the ani...
A molecular phylogenetic study of the caecal fluke of poultry, Postharmostomum ...
Valadão, Marisa C; Silva, Beatriz C. M.; López-Hernández, Danimar; Araújo, Jackson V.; Locke, Sean A.; Pinto, Hudson A.,Postharmostomum commutatum (Dietz, 1858), a parasite of the caeca of poultry, has been reported from many different parts of the world. Despite its importance, there are no molecular sequences available and its phylogenetic position is unknown in relation to other members of Brachylaimoidea, a group in which taxonomic confusion reigns. Here, morphological and molecular techniques were used to study digeneans fr...
Predatory activity of the nematophagous fungus Duddingtonia flagrans on horse c...
Braga, Fabio R.; Araújo, Jackson V.; Silva, André. R.; Carvalho, Rogério O.; Araujo, Juliana M.; Ferreira, Sebastião R.; Benjamin, Laércio A.This work was performed to determine the predatory capacity in vitro of the nematophagous fungus Duddingtonia flagrans (isolate AC001) on cyathostomin infective larvae of horse (L3). The experimental assay was carried out on plates with 2% water-agar (2% WA). In the treated group, each plate contained 1.000 L3 and 1.000 conidia of the fungus. The control group without fungus only contained 1.000 L3 in the plate...
In vitro activity of a serine protease from Monacrosporium thaumasium fungus ag...
Braga, Fabio R.; Araújo, Jackson V.; Soares, Filippe E. F.; Lima, Walter dos Santos; Mozer, Lanuze R.; Queiróz, José H.A serine protease from the nematophagous fungus Monacrosporium thaumasium (NF34a) was purified, partially characterized and tested in vitro in control of the first larval stage of Angiostrongylus vasorum. NF34a grew in liquid culture medium, producing its crude extract that was purified by ion exchange chromatography. The fractions with high protease activity were collected in a pool, and elution of proteases w...
Biological control of Fasciola hepatica eggs with the Pochonia chlamydosporia f...
Dias, Anderson S.; Araújo, Jackson V.; Braga, Fábio R.; Araujo, Juliana M.; Puppin, André C.; Fernandes, Fernanda M.; Ramos, Rafael F.Fasciolosis is a disease caused by Fasciola hepatica responsible for causing significant losses in livestock. This study aimed to evaluate the Pochonia chlamydosporia fungus (isolate VC1) on F. hepatica eggs after passing through the cattle gastrointestinal tract. For this evaluation, 1 g pellet was given in sodium alginate matrix per kilogram live weight containing 25% of fungal mycelium from isolate VC1 per a...
Ovicidal activity of seven Pochonia chlamydosporia fungal isolates on Ascaris s...
Ferreira, Sebastião R.; Araújo, Jackson V.; Braga, Fabio R.; Araujo, Juliana M.; Carvalho, Rogério O.; Silva, André R.; Frassy, Luiza N.The ovicidal effect of the nematophagous fungus Pochonia chlamydosporia on eggs of Ascaris suum was tested under laboratory conditions. A. suum eggs were plated on 2% water–agar with seven fungal isolates (Isol. 5, Isol. 31, Isol. 1, VC1, Isol. 12, Isol. 22 and VC4) and control without fungus. After 5, 7, 10, 14, 15 and 21 days of incubation, approximately 100 eggs were removed from the plates and classified ac...
Predatory activity of Pochonia chlamydosporia fungus on Toxocara (syn. Neoascar...
Braga, Fabio R.; Ferreira, Sebastião R.; Araújo, Jackson V.; Araujo, Juliana M.; Silva, André R.; Carvalho, Rogério O.; Campos, Artur K.Toxocara (Neoascaris) vitulorum is a gastrointestinal nematode parasite of young ruminants, responsible for high mortality rates in parasitized cattle and buffalo calves. The objective of this work was to compare the predatory capacity under laboratory conditions of four fungal isolates of the nematophagous fungus Pochonia chlamydosporia (VC1, VC4, VC5 and VC12) on T. vitulorum eggs in 2% water-agar (2% WA). T....
Biological control of sheep gastrointestinal nematodiasis in a tropical region ...
Silva, Andre R.; Araújo, Jackson V.; Braga, Fabio R.; Frassy, Luiza N.; Tavela, Alexandre O.; Carvalho, Rogerio O.; Castejon, Fernanda V.Formulations in matrix of sodium alginate (pellets) of the nematode predatory fungi Duddingtonia flagrans and Monacrosporium thaumasium were evaluated in the biolog- ical control of sheep gastrointestinal nematodiasis. Three groups (1, 2, and 3), each one with eight sheep of the Santa Inês breed, at the ages of 15–48 months, were placed in paddocks of Brachiaria decumbens for 5 months. In group 1, each animal r...
Efficacy of Duddingtonia flagrans and Arthrobotrys robusta in controlling sheep...
Braga, Fabio R.; Araújo, Jackson V.; Silva, Bruna F.; Mauad, Juliana R. Carrijo; Campos, Artur K.; Amarante, Alessandro F. T.The aim of this study was to evaluate the efficacy of formulations of sodium alginate matrix (pellets) of the nematode predatory fungi, Duddingtonia flagrans (AC001 isolate) and Arthrobotrys robusta (I-31 isolate), in the biological control of sheep gastrointestinal nematode infections. Thirty young Bergamacia ewes were allocated into three groups: In group 1 (control), the animals received 2 g/10 kg of live we...
Survival of Pochonia chlamydosporia in the gastrointestinal tract of experiment...
Araujo, Juliana M.; Araújo, Jackson V.; Braga, Fabio R.; Araújo, Dayane M.; Ferreira, Sebastião R.; Soares, Filippe E.F.; Benjamin, Laércio dos A.The predatory capacity of the nematophagous fungus Pochonia chlamydosporia (isolate VC4) after passage through the gastrointestinal tract of dogs was assessed in vivo against Toxocara canis eggs. Twelve dogs previously wormed were divided into two groups of six animals and caged. The treatments consisted of a fungus-treated group (VC4) and a control group without fungus. Each dog of the fungus-treated group rec...
