2010
[Objective] To investigate the sensitivity of Eimeria coccidia strains isolated from two chicken farms in Anhui Province to different anti-coccidial drugs and provide a theoretical basis for coccidiosis treatment.[Method] The fresh feces were collected from two chicken farms,and Eimeria coccidia strains were isolated and propagated in laboratory.A total of eight anticoccidial drugs including diclazuril,robenidine,dinitolmide,decoquinate,nicarbazine,maduramicin,salinomycin and lasalocid were selected for sensitivity test.[Results] In Farm I,Eimeria coccidia strains were sensitive to decoquinate,partially resistant to nicarbazine and completely resistant to other six drugs.In Farm II,Eimeria coccidia strains were sensitive to decoquinate and nicarbazine,partially resistant to robenidine and completely resistant to other five drugs.[Conclusion] Drug resistance of Eimeria coccidia to many anticoccidial drugs had been highly developed in these two farms.
