Resumen
En la actualidad el control de los nematodos gastrointestinales se realiza casi exclusivamente con moléculas antihelmínticas. La inadecuada utilización ha generado resistencia en algunos géneros parasitarios. Sumado a la preocupación de consumir alimentos inocuos en pro de la salud humana, se ha estimulado el desarrollo de otros métodos de control para las parasitosis gastrointestinales, tales como el control biológico, basado en el uso de enemigos naturales de las larvas en el medio ambiente. Entre los enemigos naturales de las larvas de nematodos gastrointestinales el más frecuentemente utilizado es el hongo Duddingtonia flagrans. Este tiene la capacidad de reducir el número de larvas de nematodos en materia fecal, y sus clamidosporas, así como de atravesar el tracto gastrointestinal y mantener su capacidad germinativa, facilitando así la posibilidad de desarrollar diferentes formas de administración. En esta revisión se mencionan las especies de hongos utilizadas hasta el momento y se discuten las distintas formas de administración de hongos nematófagos ensayadas hasta el momento.
The control of gastrointestinal nematodes relies at present mostly on anthelmintic treatments using synthetic molecules. This approach, however, has led to the appearance of resistance to some types of anthelmintics which, together with the need of cutting down on the use of chemicals, has fostered the development of other control methods, such as biological control. Biological control is the utilization of living beings that are naturally antagonistic to an unwanted species. Among the natural enemies of nematode parasitic larvae is the microfungus Duddingtonia flagrans. Research has proved the ability of this fungus to reduce the number of nematode larvae in faeces, the ability of its chlamydospores to survive the passage through the gastrointestinal tract of livestock and, moreover, to keep its germinative ability, thus facilitating the development of formulations. The present review mention the nematophagous fungi species used at the moment and deals the different ways of administering nematophagous fungi currently tested.
