Investigation of Eimeria species and Drug Resistance on Three Intensive Chicken Farms in Huaibei City,Anhui Province
摘要
Abstract
Avian coccidiosis is a widespread enteric disease caused by several Eimeria spp,causing intestinal lesions of variable extent and severity.At present,the control measures of coccidiosis mainly depend on the use of drugs.Because of the long-term use of anticoccidial drugs,the resistance of Eimeria spp has become one of the most important obstacles in the prevention and control of coccidiosis.In order to investigate Eimeria species and resistance of Eimeria spp to five common anticoccidial drugs on intensive chicken farms in Huaibei City,Anhui province,we identified Eimeria species from three large broiler farms(AH1,AH2,AH3)by oocyst morphology and multiplex PCR.The results showed that four Eimeria species were observed,including E.tenella,E.acervulina,E.mitis and E.maxima.The resistance of the field strains to five anticoccidial drugs(diclazuril,salinomycin,decoquinate,narasin,Robenidine)was tested for drug sensitivity in chickens by evaluating four common anticoccidial efficacy indexes including anticoccidial index(ACI),optimal anticoccidial activity percentage(POAA),lesion score reduction rate(RLS)and relative oocyst production(ROP).The results showed that these Eimeria species were completely resistant to other drugs except for the moderate resistance of AH2 isolate to robenidine.These results provided the information for control coccidiosis on intensive chicken farms of Huaibei city,Anhui province.关键词
