New polymorphisms of Vkork1 gene related to anticoagulant resistance of rats and mice in Italy

open access: yesPest Management Science, Volume 81, Issue 6, Page 2869-2880, June 2025.
This study firstly reports on Vkorc1 gene mutations associated to anticoagulant rodenticide (AR) resistance in rats from Italy, and in rodents from Emilia‐Romagna region. New mutations probably involved in resistance have been described and the impact of these on rodenticide resistance was then studied via molecular docking with AR.
