“…In view of the usefulness of certain soil filamentous saprophytic fungi to significantly reduce the presence and viability of the infective phases of some helminths in the feces and/or the ground (Campos et al ., 2009; Hiura et al ., 2015; Vieira et al ., 2019), in the current research wild captive bovids were successfully dewormed and then provided spores of a blend of parasiticide filamentous fungi with ovicide ( M. circinelloides ) and larvicide activity ( D. flagrans ) every 2 days during 3.5 years. This approach resulted in the numbers of strongyles lower than 120 EPG in the feces of captive Caprinae (goats and mouflon), Bovinae (bison and marshbucks) and Reduncinae (kobs); therefore, according to a 300 EPG cut-off point established at the beginning of the trial, anthelmintic treatment was not required throughout this period.…”

The control of gastrointestinal nematodes among ruminants maintained in zoological parks remains difficult due to infective stages develop in the soil. For the purpose to improve the possibilities of the control of gastrointestinal nematodes (genera Trichostrongylus, Nematodirus, Chabertia and Haemonchus) affecting wild captive bovidae ruminants belonging to the subfamilies Antilopinae, Caprinae, Bovinae and Reduncinae, commercial pelleted feed enriched with a blend of 104–105 spores of both filamentous fungi Mucor circinelloides + Duddingtonia flagrans per kg meal was provided for a period of 3.5 years. All animals were dewormed at the beginning of the trial and also when exceeding a cut-off point of 300 eggs per gram of feces (EPG). The anthelmintic efficacy ranged between 96 and 100%. The need for repeating the administration of parasiticide treatment disappeared at the 24th month of study in the Antilopinae individuals, and at the 8th month in the Caprinae, Bovinae and Reduncinae. No side-effects were observed on the skin or in the digestive, respiratory or reproductive system. It was concluded that this strategy provides a sustainable tool for preventing the contamination of paddocks where captive ruminants are maintained, decreasing the risk of infection by gastrointestinal nematodes and consequently the need of frequent deworming.

“…Prior investigations indicated the antagonistic activity of several fungal species belonging to the genera Fusarium and Trichoderma on eggs of the roundworm Toxocara canis [ 40 , 41 , 42 ]. The ovicidal activity of Pochonia chlamydosporia (formerly Verticillium chlamydosporium ) has been widely reported on eggs of trematodes ( Echinostoma paraensei , Fasciola hepatica ) and ascarids ( T. canis , P. equorum ) [ 19 , 20 , 43 ].…”

“…Most known species with ovicidal activity are Verticillium spp., Pochonia chlamydosporia , Paecilomyces lilacinus , Trichoderma spp., or Mucor circinelloides [ 18 , 19 , 20 ]. By developing the phases of adhesion, colonization, penetration, and deliberation, these fungi develop an ovicidal activity [ 21 , 22 ].…”

There are certain saprophytic fungi in the soil able to develop an antagonistic effect against eggs of parasites. Some of these fungal species are ingested by animals during grazing, and survive in their feces after passing through the digestive tract. To identify and isolate ovicidal fungi in the feces of wild captive animals, a total of 60 fecal samples were taken from different wild animals kept captive in the Marcelle Natureza Zoological Park (Lugo, Spain). After the serial culture of the feces onto Petri dishes with different media, their parasicitide activity was assayed against eggs of trematodes (Calicophoron daubneyi) and ascarids (Parascaris equorum). Seven fungal genera were identified in the feces. Isolates from Fusarium, Lecanicillium, Mucor, Trichoderma, and Verticillium showed an ovicidal effect classified as type 3, because of their ability to adhere to the eggshell, penetrate, and damage permanently the inner embryo. Penicillium and Gliocladium developed a type 1 effect (hyphae attach to the eggshell but morphological damage was not provoked). These results provide very interesting and useful information about fungi susceptible for being used in biological control procedures against parasites.

“…Although most predatory activity has been observed in time six hours after administration for all fungal isolates, only the isolated AC001 showed a statistically significant difference (p<0.05) compared to control. Hiura et al (2015) Use of nematophagous fungi as biological controllers of helminth parasites of chickens is an efficient technology, innovative and low cost with possibility of use on all production systems, especially in conventional organic systems.…”

SUMMARY Parasites are common in intensive or organics systems destined for chickens, which is more conducive to the emergence of gastrointestinal parasites, favored by direct contact with soil and other organisms. The growing demand for animal protein stimulates an expansion of production systems, increasing the stocking density. Outdoor poultry breeding systems (organic or not) that enable lower population density and higher animal welfare does not exclude these animals the presence of environmental pathogens. The control of gastrointestinal helminthosis in non-organic intensive and extensive systems is accomplished by administering anthelmintics with high cost and results unsatisfactory due to the misuse of drugs with consequent selection parasite strains resistant to chemical bases. This problem stimulate research into alternative control measures. Nematophagous fungi are used by its enzymatic action in controlled conditions and how environmental biocontrolers of larvae of gastrointestinal nematodes of livestock. This study evaluated the capacity of conidia/chlamydospores of nematophagous fungi as Duddingtonia flagrans (AC001 and CG722) and Monacrosporium thaumasium (NF34A) for cross the gastrointestinal tract of domestic chickens (Gallus gallus domesticus), and yours germination after traffic and predatory activity “in vitro” on larvae of Panagrellus spp. Fungi conidia/chlamydospores was identified in feces of chickens at times of 6, 12 and 24 hours after administration and spores viability was found after observing the germination, mycelial growth, followed by production of traps, capture and death of Panagrellus spp larvae in feces. Fungi Nematophagous are alternative control measures, efficient and innovative technology for the biological control of helminth parasites of chickens.
