Evaluación in vitro de extractos de hongos comestibles en la prueba del desenvaine larval contra Haemonchus contortus
Background. Worldwide, gastrointestinal nematodes (GIN) cause losses in livestock production, because in some animals they can cause weight loss or death. Combating these GIN has been based on the use of anthelmintics. However, the misuse of these treatments has caused anthelmintic resistance. Therefore, there is currently a search for new biological alternatives for the control of gastrointestinal nematodes. One of these alternatives is the use of fungal extracts for nematode control. Objectives. To utilize the in vitro larval exsheathment inhibition test to evaluate organic extracts of edible fungi Pleurotus eryngii, P. djamor and Lentinula edodes, against Haemonchus contortus (L3). Methodology. Extracts were prepared from the basidiomes of the fungal species mentioned. In the case of P. eryngii and P. djamor, they were placed in a hydroalcoholic mixture (methanol/water 70:30). On the other hand, L. edodes basidiomes were macerated with distilled water for 24 hours. The extracts were filtered with a cotton/gauze system and through Whatman paper (#4) and were concentrated using a rotary evaporator until the liquid residue was removed and kept at -4 °C until use. To determine the percentage of larval exsheathment inhibition, larvae were exposed to different concentrations (156.25, 312.5, 625, 1250, and 2500 μg/mL) with their respective negative controls (PBS) for 60 minutes. The effective concentration 50% (EC50) was calculated by means of probit analysis. Results. The extracts with the best activity were P. djamor and L. edodes with an effective concentration (EC50) of 533.3 and 558.5 μg/mL, respectively. Implications. This in vitro evaluation provides results that suggest the need for further in vitro studies with more fungi species and other types of extraction procedures. Conclusion. The present study demonstrated that the use of extracts of P. eryngii, P. djamor and L. edodes was shown to have in vitro anthelmintic activity against the larval exsheathment of H. contortus.
