“…and Monacrosporium spp.) and from the ovicidal group (Pochonia chlamydosporia and Mucor circinelloides) against the decrease in the rates of recurrence of helminth infections in different parts of the world [4][5][6][7][8][9][10]. In these studies, successful experiments demonstrated the great versatility of helminthophagous fungi in the classic biological control of helminths.…”

This review describes the advances acquired and proven in the use of helminthophagous fungi in the control of gastrointestinal helminth parasites in domestic animals. Old and well-known premises about parasitic epidemiology and the factors that can interfere with the best performance of biological control are mentioned. Some of the most promising fungi are Duddingtonia flagrans from the predatory fungi group and Pochonia chamydosporia and Mucor circinelloides from the ovicidal fungi group. These fungi produce resistance spores called chlamidospores. Bioverm® and BioWorma®, based on the fungus D. flagrans, are available as commercial. Biotechnological products such as nanoparticles and obtaining primary and secondary metabolites have already been obtained from these fungi. Because they have different mechanisms of action, ovicidal and predatory fungi, when used together, can present a complementary and synergistic action in the biological control of helminths. Therefore, future research in the search for new formulations, the association of fungi from different groups, extraction of new molecules, and nanoparticles of these fungi in the control of helminths in various domestic animals are desired.

“…Association of the nematophagous fungi Arthrobotrys musiformis and Monacrosporium sinense in vitro and in vivo for biological control of equine cyathostomins way to protect them from the adverse conditions that they face during passage through the gastrointestinal tract, so that they become dispersed in the pasture environments where horses are reared and can develop their hyphae and resistance structures during growth in nutrient-rich fecal pats. One way to do this is through using pellets in a sodium alginate matrix, which has been shown to be a good alternative for oral administration of nematophagous fungi (Assis et al, 2012;Braga et al, 2009;Rodrigues et al, 2020;Tavela et al, 2013). The pelleted formulation in sodium alginate is prepared using inert materials and is easily administered to animals.…”

“…During the in vivo test, all groups reached their highest levels of larval predation at 60 h after administration of the treatment (G1 -83.0%; G2 -69.1%; G3 -69.7%). The predation rate varies according to the rate of fungal release in the feces and it is common for these formulations in sodium alginate to have their peak of predatory action at 60 h after oral administration (Costa et al, 2019;Rodrigues et al, 2020).…”

“…Oral administration of fungi is the most practical way of supplying them to animals, because they have the capacity to mix with the animals' feces, such that they are released into the environment together with the parasites' eggs (Fernandes et al, 2017;Rodrigues et al, 2020). The fungal species that form chlamydospores stand out due to their ability to survive passage through the animals' gastrointestinal tract (Chandrawathani et al, 2004;Luns et al, 2018;Costa et al, 2019).…”

Bioverm® (Duddingtonia flagrans) is a fungal formulation indicated for controlling gastrointestinal nematodes in ruminants and horses, which has recently been authorized for commercialization in Brazil. The objective was to determine the efficiency of Bioverm® against larvae of gastrointestinal nematodes after passage through the gastrointestinal tract of cattle. Twelve animals were used, divided into two groups. In the treated group, a single dose of 1 g of Bioverm® per 10 kg of live weight (containing 105 chlamydospores of D. flagrans) was provided for each animal. Fecal samples were obtained from the animals in each group at 12, 24, 36, 48, 60 and 72 hours after administration. In assay A, 2 g of feces were added to Petri dishes containing 2% agar-water medium. In assay B, coprocultures were performed. In both assays, the peak of larval predation occurred within 48 hours after administration of Bioverm®. In assay A, a significant larval reduction (P < 0.05) was seen at 48 h (88.2%). In assay B, significant reductions (P < 0.05) were seen at 36 h (43.7%) and 48 h (82.3%). Bioverm® showed high predatory capacity after passage through the gastrointestinal tract of cattle and was effective for controlling gastrointestinal nematodes.
