This study was aimed at evaluating thein vitroeffect of the edible mushroom (EM) Pleurotus eryngiiagainst the eggs and larvae (L3) of Haemonchus contortus. The evaluation included acetone (AE) and hydroalcoholic (HA) extracts of the following strains: ECS-1138, ECS-1156, ECS-1255, ECS-1258, ECS-1261, ECS-1282, and ECS-1292. The HA extract of the ECS-1255 strain showed thehighest effect on mortality rates of L3 (18.83%) at 20 μg/mL. After subjecting this HA extract to a normal phase chromatography column, five fractions were obtained; fraction F5 (100% MeOH) was the most effective against eggs, with hatching inhibition percentages of 88.77 and 91.87% at 20 and 40 mg/mL, respectively. Gas chromatography-mass spectrometry (GC-MS) subjected this fraction to an acetylation reaction to determine the content of the secondary metabolites. The GC-MSanalysis showed that the F5 fraction was composed of trehalose CAS: 6138-23-4, polyols (L-iditol CAS: 488-45-9, galactitol CAS:608-66-2, D-mannitol CAS: 69-65-8, D-glucitol CAS: 50-70-4, and myoinositol CAS: 87-89-8), adipic acid CAS: 124-04-9, stearic acid CAS: 57-11-4, squalene CAS: 111-02-4, and β-sitosterol CAS: 83-46-5.

Resumen en inglés

Haemonchus contortusis a haematophagous gastrointestinal nematode (GIN) that causes severe anaemia and even death in small ruminants, negatively impacting the economic viability of farms. Traditionally, this parasite has been controlled with chemical compounds; however, inadequate use of these types of products has favoured the emergence of anthelmintic resistance. Therefore, it is necessary to search for alternatives for GIN control. Previous studies have reported the anthelmintic activity of edible mushroom extracts against H. contortus. A recent study reported that a fraction constituted of different fatty acids and β-sitosterol isolated from the basidiomata of the edible mushroom Pleurotus djamor ECS-123 has ovicidal and larvicidal activity against H. contortus. Thus, this study aimed to assess the anthelmintic activity of the pure molecules: pentadecanoic acid, palmitic acid, β-sitosterol, stearic acid and linoleic acid. For this purpose, an egg-hatching inhibition test was carried out in which the compounds were evaluated individually and in combination at a final concentration of 20 mg mL−¹. Furthermore, larval mortality was assessed using a combination of the five commercial compounds previously mentioned at different concentrations (1.25–20 mg mL−¹). Palmitic acid and stearic acid, in some combinations, inhibited H. contortus egg hatching by 100%. On the other hand, in the larval mortality test, the combination of the five compounds showed dose-dependent behaviour, and 100% mortality was obtained 24 h post-incubation. Pure molecules and their combinations have anthelmintic-like activity against the eggs and larvae of H. contortus.

Resumen en inglés

Gastrointestinal parasitic nematodes cause important economic harm to animal health, seriously affecting the livestock industry. Worldwide, economic losses from nematodiasis is reported at more than USD 10 billion a year in anthelmintic treatments alone in 2013. In Mexico, the livestock industry has reported losses of about $8.902 million Mexican pesos in the zootechnical potential of ruminants that interfere in the profitability of livestock farms. So far, these diseases have been controlled by use of anthelmintic products (AH). In addition, improper use of AH contributes to the imbalance of the environment, as well as an ecotoxicological risk to soil, plants, aquifers and beneficial organisms. In this context, the search for alternative and sustainable complementary methods that reduce the need for use of synthetic products of chemical origin, for example natural derivatives of edible fungi with a nematicidal effect, is evident. The edible fungi Pleurotus spp. possesses nutraceutical and therapeutic properties including their use as anti-parasitic. In the present investigation, in vitro effects of compounds derived from Pleurotus spp. were assessed against various stages of the parasitic nematode Haemonchus contortus. Pleurotus ostreatus had higher nematicidal activity than P. eryngii. The "F" fraction of hydroalcoholic extract of P. ostreatus mycelium showed the highest nematicidal activity (25.29%) with respect to other fractions.

FpMeOH and FMeOH fractions had the highest L4 mortality rate of 84.8 and 100, respectively at 24 and 72 h. The spent mushroom substrates (SMS) of P. djamor had biological activity against H. contortus in its egg stages and L3. Furthermore, such activity is possibly influenced by the composition and/or the type of substrate. EHA-SA11 was lethal against L3 exsheathed with a 45% mortality at 20 mg/ml at 72 h postexposure, but did not affect nematode eggs. In contrast, EHA-SA13 was the most effective against parasite eggs with 100% inhibition starting at 2.5 mg/ml that was determined at CL90= 625 μg/ml. The use of a "nutraceutical" food based on SMS of edible mushroom culture represents a potential method of prevention of nematode infections.

Resumen en inglés

The reduction of the gastrointestinal nematode (GIN) larvae population in faeces of cattle treated with Duddingtonia flagrans chlamydospores on a farm under an organic production system in Chiapas, Mexico, was assessed. Seventeen Cebu/Swiss crossbreed grazing calves naturally infected with GIN, were randomly distributed into two groups and treated as follows: Group 1, an oral administration of 2 × 10 6 D. flagrans chlamydospores/kg BW, every two days for 30 days; group 2, Control, without any treatment. Results indicated that the epg values in both groups remained similar (p > 0.05). The average number of (L3) from coprocultures from the group treated with D. flagrans had an important reduction (53.8%) with respect to the control group and it reached 75.3% maximum larval reduction at the 14th sampling; although, no statistic significance was observed (p > 0.05). Likewise, the average of larvae (L3) recovered from grass corresponding to the animals treated with D. flagrans diminished at 25.1% with respect to the control group (p > 0.05). A mixture of GIN genera including Strongyloides sp., Haemonchus sp., Cooperia sp., Trichostrongylus sp., Oesophagostomum sp. and Mecistocirrus sp., were identified from coprocultures. It was concluded that treatment with D. flagrans chlamydospores reduces the GIN larvae population in grass and in faeces of calves maintained under an organic milk production system.

Los hongos comestibles son un componente tradicional en la dieta de diversas comunidades a nivel nacional y mundial, pues poseen características nutricionales importantes. Estos hongos no solo han sido apreciados como alimentos, sino que tienen una utilidad significativa dentro de la medicina tradicional, ya que poseen compuestos con diferentes propiedades terapéuticas. Dentro de las propiedades medicinales de estos hongos se han identificado las siguientes: antinflamatorios, antihipertensivos, inmunoduladores, antivirales, antimicrobianos, anticancerígenos, antioxidantes, anticolesterolémicos, antialérgicos, insecticidas, antifúngicos y antiparasitarios (nematicidas). En el presente capítulo se ofrece un panorama general de la importancia de los productos obtenidos a partir de los hongos comestibles Pleurotus spp. en el control de nematodos parásitos de interés pecuario. Adicionalmente, se presentan los resultados de una investigación realizada en el Centro Nacional de Investigación Disciplinaria en Parasitología Veterinaria del INIFAP, sobre la obtención de productos de hongos comestibles contra nematodos parásitos de rumiantes. Finalmente, se hace énfasis en las perspectivas del uso de estos hongos.

Resumen en inglés

Edible mushrooms have been regarded as a traditional component with nutritional characteristics in the diet of various communities at global and national levels. These mushrooms have been appreciated not only as food, because they have had an important use in traditional medicine. They possess compounds with different therapeutic properties, anti-microbial, insecticides and anti-parasitic (nematicides) and so on. In this chapter an overview on the importance of products obtained from Pleurotus spp. in the control of parasitic nematodes of livestock interest is presented. Additionally, research done on products from edible mushrooms against parasitic nematodes of ruminants in the National Center for Research in Veterinary Parasitology Disciplinary (INIFAP) is presented.
