Abstract: Objective:In order to study the resistances of commensal rodents to warfarin in four areas in Jiangsu Province.Methods:According to the test methods established of the sensibility and resistance of anticoagulants for rodents by the National surveillance group on rodents resistance.Result:The average lethal doses of R.norvegicus and R.flavipectus were 18.53 mg/kg and 133.55 mg/kg respectively,the average lethal-time of two sorts of commensal rodents were 5.7 days and 6.8 days.The individuals of norregicus and flavipectus with resistance to warfarin were 4 and 2 after the test.Conclusions:It was indicated that the resistances of anticoagulants to 2 sorts of commensal rodents were enhanced and there was a tendency that anticoagulants for rodents would get resistance.
