“…Fungi of the genus Monacrosporium sp. (Monacrosporium sinense, M. thaumasium, Monacrosporium appendiculatum, Monacrosporium ellipsosporum) were evaluated by several authors, demonstrating effectiveness in the control of gastrointestinal nematodiasis of different animal species (Araújo et al 1992;Gomes et al 1999;Castro et al 2003;Assis and Araújo 2003;Melo et al 2003;Araújo et al 2006;Campos 2006;Araújo et al 2007). These results are also in accordance with the present work, since the OPG decrease was observed in the animals in the group treated with M. thaumasium.…”

Formulations in matrix of sodium alginate (pellets) of the nematode predatory fungi Duddingtonia flagrans and Monacrosporium thaumasium were evaluated in the biological 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 received 1 g/10 kg of live weight (l.w.) of pellets of D. flagrans (0.2 g of fungus/10 kg l.w.). In group 2, each animal received 1 g/10 kg of l.w. of pellets of the fungus M. thaumasium (0.2 g of fungus/10 kg l.w.), twice a week, for 5 months. In group 3 (control), the animals received 1 g/10 kg of live weight of pellets without fungus. The monthly averages of the egg countings per gram of feces of the animals of groups 1 and 2 treated were 71.6% and 61.1% smaller, respectively, in comparison to the animals of group 3 (control). The treatment of sheep with pellets containing the nematophagous fungi D. flagrans and M. thaumasium may be used as an alternative for the control of sheep gastrointestinal nematodiasis.

“…infective larvae (P \ 0.05). In a recent work, Campos et al (2007) evaluated the viability of a formulation of M. sinense in the control of bovine nematode and obtained percentage of reduction in vitro infective larvae from 90.6 to 100%. In the present work, only the isolates SF53 and NF34 showed hyphae adhered to eggshell without egg destruction, characterizing type 1 Fig.…”

“…Monacrosporium sinense and M. thaumasium are predatory species with proved action as biological control agents against gastrointestinal nematodes in domestic animals (Araújo et al 2004;Campos et al 2007). Pochonia chlamydosporia is considered ovicidal and has been successfully used in the in vitro control of helminth eggs (Braga et al 2007.…”

This work evaluated the ovicidal effect of the nematophagous fungi Monacrosporium sinense (SF53), Monacrosporium thaumasium (NF34) and Pochonia chlamydosporia (VC1) on Taenia taeniaeformis eggs in laboratory conditions. T. taeniaeformis eggs were plated on 2% water-agar with the grown isolates and control without fungus and examined at seven and fourteen days post-inoculation. At the end of the experiment, P. chlamydosporia showed ovicidal activity (P \ 0.01) on T. taeniaeformis eggs unlike the other two species, mainly for internal egg colonization with percentage results of 32.2-54.0% at 7th and 14th day, respectively. The other fungi only showed lytic effect without morphological damage to eggshell. Results demonstrated that P. chlamydosporia was in vitro effective against Taenia taeniaeformis eggs unlike the other fungi. In this way, the use of P. chlamydosporia is suggested as a potential biological control agent for eggs of this cestode.

In vitro efficacy of aqueous and ethanolic extracts of Paecilomyces lilacinus and Trichoderma longibrachiatum was assessed in the egg hatching inhibition (EHI) and larval development inhibition (LDI) of Haemonchus contortus. For the EHI assessment, after 48 h of incubation with different concentrations of aqueous and ethanolic extracts, it was quantified blastomeres, embryonated eggs, and larvae of first stage. For the LDI assessment, a quantitative coculture adapted method was used. After seven days of feces incubation with different concentrations of aqueous extract of fungi, the infective larvae were collected and quantified, obtaining the number of developed larvae per feces gram. The aqueous extract of P. lilacinus at 1.96 mg mL -1 and the ethanolic extract of T. longibrachiatum at 1.90 mg mL -1 completely inhibited the egg hatching. In the LDI, the aqueous extract of T. longibrachiatum at 1.90 mg mL -1 showed efficacy of 92.88%. These fungi extracts showed potential to inhibition of the H. contortus cycle.
