Influence of earthworms on development of the free-living stages of gastrointestinal nematodes in goat faeces
چکیده انگلیسی

With the important infection of small ruminants by gastrointestinal nematodes, and in the face of reduced efficacy of anthelminthic treatments, a search for other biological options is necessary. The effect of earthworms on the free-living stages of Haemonchus contortus and Trichostrongylus colubriformis in faeces from goats naturally infected in tropical pastures was evaluated. Two levels (0 vs 14 individuals per container) of indigenous earthworms (50% Pontoscolex corethrus and 50% Perionyx excavatus) were added to containers filled with soil and faeces collected from 20 grazing goats. After 1 week, the numbers of free-living stages of each infective larvae species was measured. The addition of earthworms reduced by 34% (P < 0.006) the number of infective larvae recovered in the faeces of goats. The reduction was significant for both larvae species, 29% and 33% for H. contortus and T. colubriformis, respectively. The ratio of the two species of larvae, without or with earthworms, did not vary significantly (P > 0.21). These results must be confirmed in experiments on pasture, with other ratios and combinations of earthworms.
