Control of infection by gastrointestinal nematodes remains a big problem in ruminants under continuous grazing. For the purpose of decreasing the risk of infection by Trichuris sp. in captive bison (Bison bison) always maintained in the same plot, dried gelatins having ≥106 chlamydospores of both Mucor circinelloides and Duddingtonia flagrans were...

The innocuousness of the prolonged ingestion of commercial nutritional pellets containing spores of the fungal species Mucor circinelloides and Duddingtonia flagrans on grazing dairy heifers was tested. During two years, one group (G-F) received daily 2.5 kg pellets with 3 × 10⁵ spores each fungus / kg pellet, and group G-C without them. In the thi...

Two different formulations containing a blend of spores of the filamentous fungi Mucor circinelloides and Duddingtonia flagrans have been assayed against trichostrongylids in wapitis captive in a grassy parcel from a zoological park and dewormed with fenbendazole. One approach (sprayed-on pellets) consisted of providing them, during 10 months, nutr...

Introdução e objetivos Os cavalos em pastoreio têm um risco elevado de infeção por helmintes gastrointestinais, nomeadamente estrongilídeos, através da ingestão de ovos ou L3 com a erva. O seu controlo em equídeos domésticos e silvestres é focado na desparasitação com anti-helmínticos (AH), com o risco de resistência e resíduos no ambiente. O cont...

The integrated control of strongyles was assayed for a period of three years in wild equids (zebras, European donkeys, and African wild asses) captive in a zoo and infected by strongyles. During three years control of parasites consisted of deworming with ivermectin + praziquantel; equids also received every two days commercial nutritional pellets...

Toxascaris leonina and Trichuris sp. are soil-transmitted helminths (STHs) infecting domestic and wild mammals. The antagonistic effect of the saprophytic filamentous fungi Mucor circinelloides and Verticillium sp. was examined on eggs of T. leonina passed in the feces of captive lynxes (Lynx lynx) kept in a zoological park. The activity of M. circ...

Control of gastrointestinal nematodes in captive wapiti (Cervus canadensis) by feeding pellets with parasiticidal fungal spores

Effect of oxyclozanide + ivermectin on paramphistomid-infected cattle from Colombia

: 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 feca...

The risk of exposure to Fasciola hepatica in horses from Uruguay was evaluated using ELISA and a recombinant surface protein (FhrAPS). Blood samples were collected from 368 horses from different districts. Detection of antibodies and the seasonal IgG pattern against the trematode was also established. The overall seroprevalence was 54% (ranging 23%...

The ability of the spores of the ovicide fungus Mucor circinelloides to resist the industrial manufacturing of pelleted feed and retain their biological and parasitological activities has been tested. Firstly, survival of M. circinelloides spores at elevated temperatures was in vitro assayed. In a second assay, the spores of M. circinelloides were...

Grazing animals become infected when ingesting forage contaminated with oocysts (protozoa), metacercariae (flukes), cysticercoids (tapeworms), eggs containing larvae inside (roundworm, whipworm) or larvae (gastrointestinal and pulmonary nematodes). Many antiparasitic drugs have been developed during decades, and most of them are commercially availa...

El control de los nematodos gastrointestinales que infectan a los caballos se basa en la administración de antihelmínticos para eliminar los parásitos adultos en los animales. En zonas en las que el clima no es extremo las larvas L3 pueden permanecer viables a lo largo de todo el año en los pastos, de modo que los équidos pueden infectarse práctica...

A preliminary study to evaluate the possibilities of biological control procedures against parasites affecting livestock reared in a care farm has been conducted. Adults with mental disabilities were involved in spreading the spores of the filamentous fungus Mucor circinelloides directly onto the faeces, or as a food additive. In the first assay, t...

Baylisascaris procyonis is a soil-transmitted helminth mainly found in raccoons (Procyon lotor) which can also affect other domestic and sylvatic animals, as well as humans, when the eggs released in the feces of parasitized raccoons are accidentally ingested. Three assays have been conducted to assess the effect of three saprophytic fungi, Mucor c...

RESUMEN "Marcelle Natureza" es un parque zoológico situado en San Martín de Guillar (Outeiro de Rei, Lugo), tiene una extensión aproximada de 20 hectáreas divididas en amplias parcelas en las que viven un número elevado de animales salvajes en semilibertad. El pastoreo continuo favorece la infección de los animales por nematodos gastrointestinales,...

Horses can be maintained outdoors or indoors. When managed outdoors, they routinely feed on domestic pastures, and are supplemented with grain and roughage when necessary. Other possibilities consist of horses grazing freely on natural pastures in woodland areas, a regime known as silvopasturing. They are never supplemented, and sufficient feeding...
