The Role of Helminthophagous Fungi in the Biological Control of Human and Zoonotic Intestinal Helminths.

ABSTRACT

Nematophagous, or helminthophagous fungi of the genera Duddingtonia, Arthrobotrys, Monacrosporium, Pochonia, Paecilomyces, and Mucor, have been used over the years in in vitro and in vivo experiments to control helminth parasites that are potentially zoonotic. These fungi have shown efficacy against the following helminth genera Ancylostoma, Toxocara, Enterobius, Strongyloides, Angiostrongylus, Taenia, Fasciola, and Schistosoma. The results obtained from these experiments, together with studies on soil contamination, suggest the viability of their use as a sustainable and effective strategy to reduce environmental contamination by these zoonotic parasites. Therefore, the aim of this review was to address the role of helminthophagous fungi in the biological control of potentially zoonotic helminths. To this end, we describe (1) a brief history of helminthophagous fungi; (2) a discussion of some potentially zoonotic intestinal parasites; (3) the importance of helminthophagous fungi in the control of nematodes, cestodes, and trematodes; and (4) the potential of helminthophagous fungi as a practical and sustainable strategy.
