“…According to Braga et al (2008), this variation produces two types of spores called conidia and chlamydospores, however, what is most observed in culture media, as well as for facilitated propagation, are the last. As reported by Buzatti et al (2017) the chlamydospores are extremely resistant structures, mainly to the detriment of the thick cell wall, this characteristic allows superior adaptability when compared to other variations of spores and prolonged permanence in the environment, added to the passage through the animal gastrointestinal tract.…”

Infections caused by gastrointestinal nematodes in sheep have become a recurring problem due to the difficulty of eradicating these parasites from the environment. The use of alternative methods, such as biological control, using nematophagous fungi, is a suitable tool for producers. The objective of this review is to provide information, disseminate knowledge, and clarify doubts. Nematophagous fungi are microorganisms adapted to survive in the soil of various cultures, feeding on present, infectious, or free-living larvae, which can also be harmful. In this work, the groups and genera of interest in the context of nematodes were compiled, dividing them according to the mode of action. It is important to note that, under appropriate circumstances, the functioning of the nematophagous fungi may be impaired, even in the presence of proven larvae. Despite the numerous applications for the use of these microorganisms, the work points out some aspects, such as temperature and humidity, as determining factors. The described study concludes the different types and genera of fungi, modes of action, predation, colonization, and habits, facilitating understanding. Some difficulties need to be overcome, such as climatic variations, lack of prey, and their misuse, which it is up to the interested researcher to manipulate.

“…Duddingtonia flagrans has been widely studied, and there are already commercial products which allow the implementation of biological control for parasites in animal production [ 12 , 17 , 18 , 19 ]. The association between different species of fungi is important to expand the spectrum of action of fungal formulations, especially if the fungi act on different targets of the life cycle of the parasites [ 20 ].…”

This study aimed to evaluate the effectiveness of the experimental formulation containing chlamydospores of Duddingtonia flagrans and Pochonia chlamydosporia fungi, against Moniezia expansa. Two experiments were carried out. The first experiment evaluated the in vitro efficacy using 1 g of the experimental formulation (V1) added to 100 M. expansa eggs and the control (V2) (without the fungal formulation). Intact eggs or eggs with alterations were counted in order to evaluate their effectiveness. The second experiment evaluated the action of the fungal formulation on M. expansa eggs after passing through the gastrointestinal tract of goats. Three groups were identified as B1, B2, and B3, which received 1.0, 1.5 g of experimental fungal formulation, and placebo, respectively. In experiment 1, all the eggs in V1 were subjected to the predatory action of fungi, while in V2, the eggs remained intact. In experiment 2, the reduction of eggs in groups B1 and B2 were 49% and 57% 24 h after ingestion, 60% and 63% 48 h after, and 48% and 58% 72 h after. The predatory capacity against M. expansa eggs shown in the tests demonstrated that experimental fungal formulation has the potential to be used on integrated helminth control programs.
