摘要: The present study represents the first description of ionophore resistance in recovered from commercial Algerian (Jijel-Algeria) broiler farms. Microscopy and intervening transcribed sequence 1 PCR (ITS1 PCR) revealed only 2 Eimeria species litter these farms- namely acervulina maxima. A pool isolates were evaluated chickens (Cobb 500) for sensitivity to 5 anticoccidial compounds-diclazuril (1ppm), lasalocid (125ppm), monensin narasin (70ppm) salinomycin (60ppm). As indicated by profiles based on lesion scores index (ACI), complete narasin, partial lasalocid, diclazuril was observed. While lack is not surprising given its use years as sole compound, monoether (narasin) polyether (lasalocid) ionophores suggests that cross-resistance has developed a segment population. fairly uniform composition among all poultry farms E. maxima more rapidly develop drugs.
