Zusammenfassung
A large proportion of sheep flocks in Spain is maintained extensively or semiextensively,therefore almost 100% of grazing floks are infected by gastrointestinalnematodes (GIN). An adequate control of these infections is necessary to avoid lossof production and to improve animal health, however, abusive use of anthelminticsdrugs has led to the appearance of anthelmintic resistance. The objective of this studywas to determine the prevalence of GIN infections in sheep flocks and study thepresence of anthelmintic resistance to benzimidazole drugs using in vivo (fecal eggcount reduction test or FECRT) and in vitro (Egg hatch assay or EHA) techniques.In the present study we found that the prevalence of infection was 98% of the flocks,85% of them with infection levels above 100 hgh. In these herds, 44% were resistantby FECRT and 49% by EHA, including flocks suspected of being resistant. Thecorrelation between the two tests was very significant, r = 0.6 (P = 0.0001).
