Use of nematophagous fungi in biological control of gastrointestinal nematodes in sheeps

Abstract

The control of gastrointestinal nematodes in sheep is almost exclusively done with chemical products that generally offer good results, however inappropriate use has generated the presence of resistance in some parasitic groups. Consistent with this, and taking into account that there is a growing concern directed towards the consumption of safe food that favour human health, has sought develop new methods of biological control that manage and control the presence of gastrointestinal parasites inside of livestock farms through the use of natural enemies against these pathogens in the environment. The nematopahgous fungi, which have properties such as the reduction of the number of larvae of nematodes in fecal matter and ease of passing through the gastrointestinal tract while preserving its germinative capacity, which facilitates the possibility of developing various forms of administration are among the more biological methods for the control of gastrointestinal nematodes in sheep. In the present review were the species of fungi nematophagous most commonly used, as well as the different forms of administration tested today.
