Distribution of non-synonymous Vkorc1 mutations in roof rats (Rattus rattus) in France and in Spain - consequences for management
International audience Rodent control is mainly done using anticoagulant rodenticides leading to the death of rodents through internal bleeding by targeting the VKORC1 protein. However, mutations in VKORC1 can lead to resistance to anticoagulant rodenticides that can cause treatment failure in the f...

International audience Rodent control is mainly done using anticoagulant rodenticides leading to the death of rodents through internal bleeding by targeting the VKORC1 protein. However, mutations in VKORC1 can lead to resistance to anticoagulant rodenticides that can cause treatment failure in the field. This study provides the first insight into the distribution, frequency and characterization of Vkorc1 mutations in roof rats ( Rattus rattus) in France and in three administrative areas of Spain. The roof rat is present in France while it was thought to have almost disappeared with the expansion of the brown rat.
