Equine gastrointestinal strongyles (EGIS) are a large group of intestinal nematodes of relevant importance in equine clinical practice. In fact, the occurrence of EGIS is often associated with various types of colics and with decreased rates of productive and other performances, rough hair coat and debilitation. Moreover, due to the diffusion of drug resistant EGIS populations and of donkey organic farms, alternative control approaches are now considered extremely necessary. By using the egg hatch test (EHT), the larval development test (LDT) and the larval mortality/paralysis test (LMT), the in vitro anthelmintic properties on EGIS of some plant compounds (10 extracts and 1 pure principle) and of some nematophagous fungi (NF; n. 6), were investigated. For comparison, untreated controls were used in all cases, while in the case of plant compounds, 1% thiabendazole treated (1% TBZ) controls were also used. Throughout the experiment, three repetitions were made. Data were statistically elaborated by using one way ANOVA and post-hoc Tukey tests and statistical significance was set at P<0.05. Among plant-derived compounds, in EHT Carica papaya (at 5% and 10%), Lespedeza capitata (at 1%), Medicago arborea (at 2%), Medicago sativa (at 2%) and Laurencia + Palisada algae (at 10%) extracts showed an efficacy comparable to that of the reference drug (P<0.05). In this same test, a significant (P<0.05) reduction of the hatch of the eggs was observed in plates treated with Metarhizium anisopliae, Beauveria bassiana, Pochonia chlamydosporia and Scopulariopsis brevicaulis respect to the untreated controls. In LDT, Duddingtonia flagrans almost completely prevented the larval development from L1 to L3 in respect to the untreated controls (P<0.05). In LMT, larval mortality was significantly higher (P<0.05) in plates containing the NF species Arthrobotrys oligospora, while among plant compounds 1% Glycyrrhiza glabra and 2% M. sativa extracts were as effective as 1% TBZ. Obtained results encourage further ...
