title: The development and use of a test to identify resistance to the anticoagulant difenacoum in the Norway rat (Rattus norvegicus).
abstract: Feeding tests were carried out in the laboratory to obtain basic data on the susceptibility of wild Norway rats to difenacoum. The results were used to derive a standard test procedure for the identification of difenacoum resistance in warfarin-susceptible and resistant rats. Details are given of tests on rats from suspected difenacoum-resistant infestations on farms.
