“…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.

We aimed to evaluate a Brazilian commercial formulation of the fungus Duddingtonia agrans (Bioverm®) for controlling gastrointestinal nematodes in sheep kept on native pasture in the Caatinga biome, in the semiarid region of Brazil. Twenty ewes, aged between 12 and 18 months, were divided into two groups. In the treated group, each animal received 1 g of the Bioverm® product for each 10 kg of live weight, daily, together with commercial feed, for six months. In the control group, the animals received feed without Bioverm®. Each group remained throughout the experiment in a 1.2 ha paddock. Monthly counts of eggs per gram of feces (EPG), fecal cultures, packed cell volume (PCV), weight measurements and collection of leaf mass from the pasture were performed. There was greater reduction in EPG, greater weight gain and less infestation by infective larvae in the paddock of the Bioverm® group, compared with the control group (p < 0.05). There was no signi cant difference (p ≥ 0.05) in the mean PCV percentage between the Bioverm® and control groups. In coprocultures, Haemonchus sp. was the most prevalent helminth. Bioverm® (D. agrans) was e cient for biological control of sheep gastrointestinal nematodes in the semiarid region of Brazil.
